The increase in the pH of the solution increases the solubility of the given ionic compounds such as $\bold {CuS }$ and $\bold {CuI}$ .

Solubility & pH:The solubility of the ionic compound increase with a decrease in the pH of the solution because it shifts the equilibrium in water.The solubility is unaffected for the conjugate bases of the strong acids.

All given compounds are ionic compounds,

Therefore, the increase in the pH of the solution increases the solubility of the given ionic compounds.

Ca3(PO4)2- Increase in solubility

Barium hydroxide- increase in solubility

Magnesium carbonate- increase in solubility

Copper II sulphide- increase solubility

Lead II bromide- increase solubility

CuI - increase solubility

Explanation:

Calcium phosphate solubility is pH dependent. At lower pH, calcium phosphate is more soluble in water while at pH above 8.5, the solubility of calcium phosphate decreases markedly.

For Barium hydroxide and magnesium carbonate,decreasing the pH will increase the solubility of the compound.

For copper II sulphide,decreasing the pH will lead to a greater solubility. Also, lead II bromide is ordinarily insoluble in water but it's solubility increases with decreasing pH.

CuI is insoluble in water but soluble in dilute hydrochloric acid.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
