A white coloured inorganic salt gives the following reactions.

(i) It is soluble in water and the solution has sweet taste.
The solution turns black in presence of $H_{2} S$
ii) The solution gives a white precipitate with dilute HCl which is soluble in hot water.

iii) The salt when heated gives acetone and a yellow coloured residue. Identify the salt (A) and give chemical reactions.

Options:

A . NaCl

B .

S n (H C O O)_{2}

C .

P b (C H_{3} C O O)_{2}

D .

C a C O_{3}

Answer: Option C
:
C

$(A) i s P b (C H_{3} C O O)_{2} P b (C H_{3} C O O)_{2} + H_{2} S \to P b S + 2 C H_{3} C O O H Black P b (C H_{3} C O O)_{2} + 2 H C l \to P b C l_{2} + 2 C H_{3} C O O H Soluble in hot water P b (C H_{3} C O O)_{2} \to P b O + C O_{2} + C H_{3} C O C H_{3}]$
