I have a doubt in calculation, what is 5000?

For mixed Indicator, I think the right weight is 0.2g Methyl Red and 0.1g Bromocresol green Not 0.02g Methyl Red and 0.01g Bromocresol green.

Already uploaded. 1. Watch sample preparation by Wet Digestion Method for Lead analysis and prepare your sample accordingly. 2. Then analyze the prepare sample using AAS as described in Sodium Analysis of Salt.

why we can't only do total alkalinity? what's the difference
@MicroChemsExperiments
3 жыл бұрын
If you want to find the total alkalinity you have to do sum of phenolphthalein alkalinity and mixed indicator alkalinity. Because two indicators work in different ph range and the whole ph range is the total alkalinity which can't be determined by only a singe indicator.

Prasanna Udaya Kumara, IS reference method said to use H2SO4. So you should use sulfuric acid.
