Question

How could you manipulate a solution in a lab to form more precipitate? Select all that apply

Heat the solution. 

Remove the solid from the solution as it forms. 

Add more solid to the solution.

Add more ions to the solution. 

Answer 1

Based on Le Chatelier's Principle, if you have A⁺(aq) + B^-(aq) ==> C(s)

Removing the precipitate as it forms, will cause more precipitate to be formed.

Adding more ions, such as A+ or B- will cause more precipitate to be formed.

Heating will more than likely reduce the amount of ppt formed as it will probably increase solubility.
