Separating salt and sodium carbonate help

George3

1. The problem statement, all variables and given/known data
Given a mixture of salt and sodium carbonate, how could you determine the amount of sodium carbonate in the mixture?


2. Relevant equations



3. The attempt at a solution
Salt and sodium carbonate are both soluble, so I would I use HCl to react with the Na2CO3 leaving the NaCl H20 and CO2? And then boil the salt water?

Not a chemist, but sodium carbonate must be acidic in water - could you just do a titration ?

Borek

Quite the opposite, it will be slightly basic

But titration (with a strong acid) is still a good idea.

Doh - Sodium Carbonate is washing soda, must be alkali!
