Question

give the number ratio of oxygen atoms in the case of the following pairs of molecules. 1. nitrous acid & nitric acid 2.sulpurous acid & sulphuric acid 3. phosphorus acid& phosphoric acid 4. calcium nitrate & ammonium nitrate 5.aluminum hydroxide & calcium hydroxide 6. aluminium sulphate & calcium phosphate 7. chloric acid& perodic acid 8.sodium carbonate & aluminum nitrate. plzzzzz solve this

Answer 1

1. nitrous acid & nitric acid 2:3

2.sulpurous acid & sulphuric acid 3:4

3. phosphorus acid& phosphoric acid 3:4

4. calcium nitrate & ammonium nitrate 2:1

5.aluminum hydroxide & calcium hydroxide : 3:2

6. aluminium sulphate & calcium phosphate: 2:1

7. chloric acid& perodic acid 1:1

8.sodium carbonate & aluminum nitrate. 1:3

Explanation:

• the number of oxygen atom in every type of compound depend on the characteristics of the anion and cation.

• In other words it depends on the valency of the compound. for example in case of calcium nitrate the valency of calcium is to whereas in case of ammonium nitrate the valency of ammonia is one. Hence the ratio of oxygen in the to compound is 2 is to 1
