Question

Question 2 (iii)
Write down the names of compounds represented by the following formulae:
$\left(iii\right)K_{2}S{O}_4$

Answer 1

$\left(iii\right)K_{2}S{O}_4$ :
$K$ is the symbol for potassium and $S{O}_4$ is the symbol for sulphate ion. From the chemical formula, it is evident that potassium is the cation and sulphate is the anion. We know that the name of cation precedes the anion. So, the name of the given compound is "Potassium sulphate"
