A white coloured inorgatnic salt formed by an element fo group `14` give the following reactions :
a. It is soluble in water and the solution has sweet taste .
The salt when heate gives acetone and a yellow colured reside which is used in paints . ltbr. e. The solution of the salt gives a wihiter precipitate with dil HCi which is soluble in hot water .
Explain the above observations with chemicl reactions invovled .

Explanation

White coloured inorganic salt formed by an element of group `14` is lead acetate, `(Ch_(3)COO)_(2)Pb`, which is commonly known as sugar of lead.
` (CH_3COO)_2 Pb + 2H_2O rarrr 2CH_3 COOH + Pb(OH)_2`
b. Lead acetate on heating decompeses to give acetone and `PbO`, a yellow coloured residue which is used in painsts .
`(CH_(3)COO)_(2)Pb overset(Heat)(rarr)underset(("Yellow residue")) underset("Lead chloride) (PbCl_(2) darr+)2CH_(3) COOH`
c. When dil `HCl` is added to the solution of lead acetate . a white ppt. of `PbCl_2` appears which is insluble under cold conditions , but dissolves on heating
`(CH_3 COO)_2 Pb +2HCL rarr underset (("white ppt.")) underset ("Lead chloride") (PbCl)2 darr + 2CH_3COOH`.
