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

Potassium is denoted bythe symbol K⁺ and phosphate is symbolized by\(P{O_4}^{3 - }\).

The positive part is the metal (K) which will come first in the formula, and phosphate will come last.

For satisfying three negative charges, three potassium ions will be required.

So, the formula of potassium phosphate isK₃PO₄.

Copper (II) is denoted by\(C{u^{2 + }}\)_,andsulfateis denoted by\(S{O_4}^{2 - }\)_.

So, the formula of copper (II)sulfateis CuSO_4.

Calcium is denoted by\(C{a^{2 + }}\)_,and chloride is denoted by\(C{l^ - }\)_.

For balancing two positive charges, two negative charges will be required.

Thus, the formula of calcium chloride is CaCl_2.

Titanium (IV) is denoted by\(T{i^{ + 4}}\)_,and oxide is denoted by \({O^{2 - }}\).

For balancing the charges, two ions of oxide are required.

The formula for titanium dioxide is TiO_2.

Ammonium is denoted by \(N{H_4}^ + \)_,and nitrate is denoted by \(N{O_3}^ - \)_.

The formula for ammonium nitrate is NH₄NO_3.

Sodium is denoted by\(N{a^ + }\)_,and bisulfate or hydrogen sulfate is denoted by\(HS{O_4}^ - \)_.

The formula for sodium bisulfate is NaHSO_4.
