State whether the following statements are true or false:

The formulae of the salts is:

Salt	Chemical Formula
Potassium sulphate	$K_{2}S{O}_4$
Sodium sulphate	$NaS{O}_4$
Calcium sulphate	$CaS{O}_4$
Magnesium sulphate	$MgS{O}_4$
Copper Sulphate	$CuS{O}_4$
Sodium chloride	$NaCl$
Sodium nitrate	$NaN{O}_3$
Sodium carbonate	$N{a}_{2}C{O}_3$
Ammonium chloride	$N{H}_{4}Cl$

In the salt's chemical formula, the metal ion is written first. The quantity of cations or anions must be written in such a manner that the salt loses its charge and turns neutral.

Potassium sulphate-K_2​SO_4​

Sodium sulphate-Na_2​SO_4​

Calcium sulphate-CaSO_4​

Magnesium sulphate-MgSO_4​

Copper sulphate-CuSO₄​

Sodium chloride-NaCl
Sodium nitrate-NaNO_3​

Sodium carbonate-Na₂​CO₃​

Ammonium chloride-NH_4​Cl

Hence, the given statement is true.
