Determination of the Carbonate Content of a Soda-Ash …

Phenolphthalein indior is added to the carbonate solution which is then titrated with HCl until the pink color has just disappeared, which will occur at an approximate pH of 8. Since the equivalence point is at pH 8.4 an amount of acid somewhat in excess of one equivalent is used, and the titration gives only a rough measure of the carbonate content of the original solution.

drinking Water treatment: carbonate removal and/or …

When the raw water contains more calcium than bicarbonate (CaH >> M-alk.), carbonate removal using sodium hydroxide may be an option (alternative: lime + sodium carbonate). In order to ensure that the water is pleasant to drink, a certain M-alk. will have to be re-instated by mixing the water with a fraction of water from which the carbonates have not been removed.
