Name the gaseous products from the following A and B reactions respectively .
A . Hydrochlotic acid is added to sodium sulphide.
B. Conc. Sulphuric acid is added to a mixture of sodium chloride and manganese dioxide.
The correct answer is

A

`Cl_2, Cl_2`

B

`H_2,HCl`

C

`H_2S,O_2`

D

`H_2S,Cl_2`

Text Solution

Verified by Experts

The correct Answer is:
D
(A) When hydrochloric acid reacts with sodium sulphide, hydrogen sulphide gas ans sodium chloride are produced.
`2HCl(aq)+Na_2S(aq)rarrH_2S(g)+2NaCl`
(B) Manganese oxide react with conc. Sulophuric acid and sodium chloride to produce manganese sulphate. chlorine, sodium sulphate and water.
`MnO_2+2NaCl+2H_2SO_4rarrMnSO_4+Cl_2(g)+Na_2SO_4+2H_2O`
Hence, option (d) is the correct answer.
