Question

2. Write the formulae and valencies of
each of the following ions:
(a) Potassium ion (b) Ammonium ion
(c) Oxide ion
(d) Hydroxide ion
(e) Sulphate ion (f) Nitrate ion
(g) Carbonate ion (h)Carbon ion
(i) Chloride ion (j) Sulphide ion​

Answer 1

Explanation:

1. Potassium ion = K+ Valency = 1
2. Ammonium ion = (NH4)+ Valency = 1
3. Oxide ion = O²- Valency = 2
4. Hydroxide ion = OH- Valency = 1
5. Sulphate ion = (SO4)²- Valency = 2
6. Nitate ion= NO3 - Valency = 1
7. Carbonate ion = (CO3)²- Valency = 2
8. Carbon ion = C⁴- Valency = 4
9. Chloride ion = Cl- Valency = 1
10. Sulphide ion = S²- Valency = 2
