Cation means a positively charged ion. Anion is a negative one
Answer:
Solubilities of 
increases with increasing acidity
Explanation:
Concentration of 
decreases with increasing acidity. Therefore solubility of 
increases to keep constant solubility product.
Concentration of 
decreases with increasing acidity due to formation of 
. therefore solubility of ZnS increases to keep constant solubility product
Increasing acidity have no effect on this above equilibrium. Therefore solubility of 
remains constant.
Concentration of 
decreases with increasing acidity due to formation of 
. Therefore solubility of 
increases to keep constant solubility product.
Increasing acidity have no effect on this above equilibrium. Therefore solubility of NaI remains constant.
Concentration of 
decreases with increasing acidity due to formation of 
. Therefore solubility of 
increases to keep constant solubility product.
