The product obtained on fusion of `BaSO_(4)` and `Na_(2)CO_(3)` is

Can we perform the charcoal cavity test without the addition of fusion mixture (Na_(2)CO_(3) and K_(2)CO_(3)) with the carbonate of metals?

Fusion of AgCl with Na_(2)CO_(3) gives:

A saturated solution of BaSO_(4) at 25^(@)C is 4xx10^(-5) M. The solubility of BaSO_(4) in 0.1 M Na_(2)SO_(4) at this temperature will be

BaSO_(4) and BaCrO_(4) have solubility product values in the ratio 1:2.5 at 25^(@)C . When pure water is saturated with both solids simultaneously, the total concentration of Ba^(2+) ion in the solution is 1.4xx10^(-5)M . Calculate the solubility product of BaCrO_(4) . Calculate also the solubility of BaSO_(4) in 0.01M Na_(2)SO_(4) solution.

The useful by products obtained in the Solvay process of manufacture of Na_(2)CO_(3) are :

BaSO_4 on fusing with Na_2CO_3 gives:

AgCl on fusion with Na_(2)CO_(3) gives
