Question

write the formula of the following compounds, showing the steps involved. a) Aluminium Sulphate b) Potassium Nitrate

Answer 1

Answer:

a. valency of Al = 3

valency of sulphate radical (SO4) = 2

So, formula of aluminium sulphate ---> Al2(SO4)3

b.valency of K = 1

valency of nitrate radical (NO3) = 1

So, formula of potassium nitrate ---> KNO3

Answer 2

The formula of (a) Aluminum sulphate is Al2(SO4)3

(b) Potassium Nitrate is KNO3. ANS
