DETERMINATION OF COD OF WASTE WATER-Part-1 

Same here

​@Divya Kumar legend

Same but I'm watching at 1 30 at night 😂

Me too

Me too at 1:45 am 😀

Thank you

Thank you

Thank you

Thank you

Thanks and welcome

Are u from sdm if yes reply me back

​@@sandeepkarne3913 yea

Thank you God gift

Thank you so much for your nice feed back and encouragement and for more lecture videos please subscribe my channel

Thank you

Thank you

2 test tubes Thank you

Which acid?

Thank you 1:1 Water :H2SO4 solution but care full and take the help from the known persons while preparing

Thank you

Yes required but in this method I have used FAS instead of waste water Hence not required

Thank you Yes required based on the impurities in the waste water

Thank you is definitely required if the waste water contains more contaminants But only for this titration I have taken only one contaminant

Thank you

Yes definitely it is required if you have more impurities in the waste water But I have used only one FAS as impurity in waste water for this heating is not required Thank you so much for your nice feed back and encouragement and for more lecture videos please subscribe my channel

Thank you Yes it is necessary if required

Thank you Yes you need to heat if required and the waste water if it contains more contaminants But only for this titration I have taken only one contaminant and which will give the end point without heating.

Use dilute FAS solution

Yes required but in this method I have used FAS instead of waste water Hence not required

Thank you

Thank you Silver sulphate is definitely required if the waste water contains more contaminants But only for this titration I have taken only one contaminant

Thank you

Will upload soon Thank you

Thank you

Thank you

concentrated sulphuric acid diluted with distilled water in the ratio 1:1 Thank you so much for your nice feed back and encouragement

Thank you Mixture of Water and H2SO4 in the ratio 1:1

Equal amount of water and concentrated sulphuric acid

Actually we are using very dilute solutions so ...

pipetting any chemicals by your mouth is not permitted in laboratory process

This is for all science students to determine COD of waste water. Thank you

Thank you

Thank you
