Explanation:

Step1: Determine ion charges

Sodium ion ($Na^+$) has a +1 charge. Hydrogen phosphate ion ($HPO_4^{2 -}$) has a - 2 charge. To form a neutral compound, we need 2 sodium ions for every 1 hydrogen - phosphate ion.

Step2: Write chemical formula

The chemical formula is $Na_2HPO_4$.

Step3: For sodium and acetate

Sodium ion ($Na^+$) has a +1 charge. Acetate ion ($C_2H_3O_2^-$) has a - 1 charge. They combine in a 1:1 ratio.

Step4: Write chemical formula for sodium acetate

The chemical formula is $NaC_2H_3O_2$.

Answer:

Part C: $Na_2HPO_4$
Part D: $NaC_2H_3O_2$
