I've been watching a lot of your videos lately, thank you. I'm looking for a video that will explain how to calculate the theoretical pH-value for solutions. For example, how to calculate the theoretical pH for a 2.5 mmol/L H2PO4- solution and a 5.0 mmol/L NH4+ solution. There are apparently different formulas based on strong, middle or weak acids, and for strong, middle or weak bases. I'm learning it in a language other than English (Danish), which adds to my confusion since I'm not a native Danish speaker. I'm looking for a good explanation in English. Do you have a video that teaches this? Thanks in advance.
I have a question for you. How can we have OH and H in a solution forever and never have a reaction between them? I say forever because you can have steady ph forever in a solution. I would imagine if you put OH- and H+ in a solution it would react quite quickly and neutralize each other to a point where you only have H+ or OH-. And that’s when H,H2CO2, HCO3,CO3,OH concentrations becomes important for PH calculation.
Is there a statement in the video that is confusing you here? If so let me know the time. OH- and H+ are in a dynamic equilibrium so there is a constant interaction back and forth between the ions, some react and neutralize and some remain dissociated
@@ChadsPrep thank you so much sir. Everyday I watching ur videos especially organic chemistry, I love chemistry from my childhood, now doing PhD and my goal is become a scientist. Sir one doubt actually am from India shall I apply for DAT, OR MCAT exams?
