i) Auric chloride ii) Ammonium sulphite
iii) Potassium permanganate iv) Sodium thiosulphate

Answer 1

(i) Auric chloride : $AuC{l}_3$ : Cation in Auric chloride is $A{u}^{+}3$ and anion is chloride ion.

(II) Ammonium sulphate : $(N{H}_4{)}_{2}S{O}_3$ : Cation in Ammonium sulphate is $N{H}_4$ and anion is permanganate and is sulphate ion.

(iii) Potassium Permagnate : $KMn{O}_4$ : Cation is potassium $\left(K^{+}\right)$ and anion is permagnate ion.

(iv) Sodium Thiophosphate : $N{a}_2{S}_2{O}_3$ : Cation is Sodium $\left(N{a}^{+}\right)$
