Question

4.- Determine if the solubility of Mercury will diminish or increase when Mercury () Sulfate is in a solution of 0.001 M Sodium sulfate. The solubility will diminish increase?roding Na2S4 5.- Explain why a colloidal dispersion will sediment at different rates if instead of adding a Ba Aluminum hydroxide is added. Which one will sediment faster? The colloidal dispersion will sediment faster with Ba Cl2 0r Al(OH) Select the proper explanation: a.- adding a salt with a cation with the higher oxidation number will increase the sedime because it will increase the Z potential b-adding a salt with a cation with the higher oxidation number will increase the sedin because it will decrease the Z potential dding ralt with an anion with the higher oxidation number will increase thes

Explanation / Answer

4. In presence of common ion , the solubility will decrrease.

The solubility will dimisnish after adding mercury sulfate.

5.

Colloidal suspension will sediment fast in presenec of Al(OH)3 because

(b) adding salt with a cation with the higher oxidation no. will increase sedimentation it will decrease Z - potential
