Question

the valency of Aluminium is 3 write the valency of other radical present in the following compounds (a )aluminium chloride. ( b) Aluminium oxide( c )aluminium nitride( d )Aluminium Sulphate​

Answer 1

Answer:

(a) Aluminium chloride — (AlCl3) here valency of Al is 3.

Other radical – Chloride (Cl–)

Valency of chloride = 1

(b) Aluminium oxide — (Al2O3)

Here valency of Al is 3

Other radical present = oxide (O2-)

Valency of O2- = 2

(c) Aluminium nitride — (Al N)

Here valency of aluminium = 3

Another radical = Nitride (N3-)

Valency of nitride (N3-) = 3

(d) Aluminium sulphate — Al2(SO4)3

Here valency of aluminium is 3

Another radical = Sulphate (SO42-)

Valency of (SO42-) = 2
