Question

An unknown mixture contains one or two of the following :

$C a C O_{3}, B a C l_{2}, A g N O_{3}, N a_{2} S O_{4}, Z n S O_{4} a n d N a O H$ .

The mixture is completely soluble in water and solution gives pink colour With phenolphthalein. When dilute hydrochloric acid is gradually added to the solution, a precipitate is formed which dissolves with further addition of the acid.

The white precipitate is_______.
