Question

Bicarbonate and sulfuric acid reaction endpoint colour methyl orange

Answer 1

For one mol sulphuric acid, one mol sodium carbonate react and since reaction is neutralizes the acidity it can be counted as one-way reaction. You can either measure the pH changes or observe the carbondioxide which will be come out of the solvent.

Na2CO3 + H2SO4 --> Na2SO4 + H2O + CO2

This is the reaction. 0.02 Normal sulphuric acid is 0.01 M , pH of solution should be neutralized at the time you added same amount of sodium carbonate, or carbondioxide emission should be stopped.
