a. Ca(H₃PO₄)₂

b. FeSO₄

c. CaCO₃

d. MgO

e. NaNO₂

f. KI

Step-by-Step Solution

Answer

a. Calcium dihydrogen phosphate

b. Ferrous Sulphate

c. Calcium Carbonate

d. Magnesium Oxide

e. Sodium Nitrite

f. Potassium Iodide

Step 1: Naming of a chemical compound

While naming a chemical compound, the positive atom will come first and is subsequently led by the negative part of the compound.

 

For example- While naming Common Salt, i.e., NaCl, the positive part of the compound is sodium, and the negative part is chloride. Thus the name of the compound is sodium chloride.

Step 2: Determining the name of the chemical compound

Calcium is denoted by\(C{a^{2 + }}\)_, and dihydrogen phosphate is denoted by \({H_2}P{O_4}^ - \). Thus the name of the compound is Calcium dihydrogen phosphate.

Step 3: Determining the name of a chemical compound

FeSO₄ is the ionic form of \(F{e^{2 + }}\) and\(S{O_4}^{2 - }\)_. The name of this compound is ferrous sulfate.

Step 4: Determining the name of a chemical compound

CaCO₃is the ionic form of \(C{a^{2 + }}\) and \(C{O_3}^{2 - }\). Thus the name of this chemical compound is calcium carbonate. 

Step 5: Determining the name of a chemical compound

MgO is the ionic form of \(M{g^{2 + }}\) and \({O^{2 - }}\) . Thus the name of this chemical compound is magnesium oxide.

Step 6: Determining the name of a chemical compound

NaNO₂ is the ionic form of \(N{a^ + }\) and \(N{O_2}^ - \). The name of this chemical compound is sodium nitrite.

Step 7: Determining the name of the chemical compound

KI is the ionic form of \({K^ + }\) and \({I^ - }\) . The chemical name of the compound is potassium iodide.
