Thank you , I'm glad I found this video , I just bought a pH meter didn't know you needed a solution to calibrate, and Im happy to find out it's an easy fix/replacement with baking soda
Full fat Milk is 6.3 to 6.5 ,cup of black coffee will be 5ish . If I'm out of buffer and I'm unsure I'll cal to 6.4 in milk and check in coffee, I've checked it to a buffer and been .1 out eveytime ,mix your feed to 6.7 you should be good
Thanks - somehow right and also wrong. Yes, the city water can have different PH, but it won't matter regarding this because if has very very very few alkalinity ... ;-)))
@@ImakeITHappEN510 Thanks. If you have something with high alkalinity and something with low alkalinity the one with high alkalinity will "win" - the other one won't matter ... ;-))
Oh, cool - didn't know. Is it the same with every brand? The thing is just ... I need it to test the pool PH and 2.5 is way off and so the 7.9 is much closer to the optimal swimming pool PH and hence I think it will be more accurate. Just my thinking.
@@allcheckout im needing to to from regular 6 or so to 10.78 my ph sick is new. Just the small yellow handheld one. It came w 2 buffers. I already calibrated it w the 7ph buffer. It came qith 2 packets...was i supposed to buffer to calibrate with both?? And everytime i use it?
@@Ic_truth OK - I'm somehow able to remember the two buffers, but not in detail. So one is PH 7.0 and the other one is what PH? When it's perfectly adjusted, usually it stays for quite some time. I used it for checking PH in our pool (which should be between 7.2 and 7.4) and so I used the test-strips from Clorox and additionally this meter to double check and do fine-tuning. Just re-adjusted every 6 months or so. What are you planning to test?
Hi i have read if you mix 1g potassium chloride per 100ml ph4 buffer solution (you can use ph7 buffer but ph 4 is best as i guess potassium chloride raises the ph slightly) you can make your own cheap KCL pH Probe Storage Solution (3 Molar KCL) ? Have also read leaving 3M Kcl out in open is okay for 2-3months but then needs replacing if your storing a ph probe pen in it (which is best way to store ph pens as there is gel on the glass bulb that dries out quickly). Tap water leeches ions from the pen. Reverse osmosis water is even more worse than tap water.
This seems really arbitrary. Although my chemistry exp is minimal. Shouldn't these measurements of both BS and tap water be more exact in order to say that this mixture should yield a ph of 7.9?
I'm still doing it same way and it works perfectly. Every now and then I double check and it seems it's still in sync. If you don't like it - don't use it. Don't see the problem. The water has no effect anyway because BS has high alkalinity.
From what i understood is you put any amount of baking soda, the amount that will dissolve in water is only enough to get to 7.9 the rest will not dissolve, is that correct??
Bro the soda has to be cooked or backed for two 3 hrs I use stove low minimum heat and cook the fumes are co2 to open windows then test I have had readings as high as 10 11
Heating baking soda makes it transform from sodium bicarbonate into sodium carbonate, which is a stronger alkaline salt. Baked baking soda is useful for applications in which a strong alkaline salt is required, such as in making ramen noodles.
This is why I found some cheap meters that have ATC (automatic temperature compensation). Rock steady regardless of the water temp because here the water temp could be 10c all the way up to 45c depending on the time of year, if in the sun, and how much of it there is. I don't want the hassle of trying to get my water precisely 25c per test.
I just bought a hanna ph checker. I was going to return it because the solution packets are crazy expensive and they say you have to store it in solution plus their cleaning solution. I am suppose to calibrate it in ph buffer 4 and 7. How can I calibrate with this or a cheaper way? Or is this just to verify that your ph meter is working? For my salt water aquarium.
Store in KCl solution, 1 to 3 mole. Mix 125 grams of Potassium Chloride in 1 Liter of distilled water. This will give a little over 1 1/2 mole solution. Place the electrode in the solution. This helps the electrodes from being depleted of ionic viability.
@@obviouslytwo4u Thanks - I love Himalayan salt ... for the color ... lol. Is it really healthy ...? Not so sure when you check where and how it's obtained ....
These pH meters should be calibrated every time one use them... Also keep the probe wer in cleaning solution to not letting it dry. The meter should also frequently be used... These are not toys and require quite a lot attention.
I've got an idea. Get a bottle of mineral water and usually label says the pH of the water and calibrate your meter accordingly.Hey! don't forget to drink rest of the water. Problem solved. What do you think guys?
Thanks - definitely not the most awful idea. Will definitely try. The only problem could be that it's not a 'buffered' solution and hence anything can affect the ph value easily (e.g. remainders from dishwasher)
@@allcheckout Totally lost you. Remainders from dishwasher in bottled mineral water! If rocket science precision required for hydroponics, you better ask NASA
@@shafiqrevolt To measure the water with the ph meter you have to fill it into something ... usually a glass ... cleaned by a dishwasher .... but could also be a one-way plastic cup ... for sure much better for this purpose ;-)
So, I’m still none the wiser on how to calibrate my ph pen using the baking soda. Thanks for showing me how to check a liquid solution with an un calibrated ph pen
I think he is establishing the baking soda in water will equilibrate around 7.90 ph. So I think he is saying if it reads 7.90 or very close in baking soda water, consider it calibrated. If not, turn the screw he showed at the back.
No, you won't get neutral (PH 7.0) reading. PH of soda ash is about 11.4. I don't see the point, why ppl would try to make soda ash instead of this, especially when you went it to calibrate it for your swimming-pool (PH 7.2 - 7.4), because PH of normal baking soda is much closer to what you want.
Very good question. In theory YES, but distilled water is almost never 100% pure, especially after opening the bottle. Additionally to have a reliable reading the alkalinity should be very high and the alkalinity of distilled water is super low. Hence I will still go with the baking soda ... but thanks anyway ;-)
Well for example if my tap water is at a ph of 8.7 before I add baking soda and your tap water is at a ph of 5.7 before you add baking soda do you think the ph will always be 7.9 after the baking soda is added?
@@allcheckout I just use it to know where my pH meter is at if it's 10 points over then I always know to pH 10 points - (if my goal is 6.5 then my ph meter should read 7.5) - higher than my Target goal, hope this helps somebody( please help support my page I just started it) my boy got cracked by the police a year ago he got 6 years( because he had some poppy plants in his indoors garden here in the 702) he gave me over 200 pack of new and old strains/magic beans so the menu is going to get very interesting, if you help me promote my channel I'll send you some beans(u have my word) Hosanna El Elyon,, Shalawam Ahch🖖✌🖖✌(702 out).........
@@the_dude_grows7392 "Baking soda is an alkaline substance". Period! If you generate 4.5 PH with something then it's NOT baking soda or you start with a PH value much lower which would be very strong acid!
Actually, distilled water absorbs CO₂ from the atmosphere. Each CO₂ molecule combines with an H₂O molecule to create an H₂CO₃, or carbonic acid molecule. Depending on atmospheric pressure and how long the water has been exposed to it, the pH could be anywhere between 5.8 and 7.0. That's why buffer solutions are used to calibrate pH meters. Buffers resist pH changes from environmental factors.
@@allcheckout Yes, I bet so because I noticed this a few years ago as Arm and Hammer listed bicarbonate first then sodium whereas the generic store brands were sodium first then bicarbonate. On the boxes the percentage of bicarbonate in A&H was higher (the reason that ingredient was listed first) than the generic store brands as well. If I remember right it was 2% to 3% more bicarbonate in the A&H which means less salt (sodium) than the generic store brands. I was looking for heartburn reasons as I need the bicarbonate not the sodium more.
