Which of the following statement `is//are` correct?
Excess of `H_(2)(g)` is bubbled into `1.0 L` of `0.1 M CuCl_(2)` solution.
`Cu^(2+) + H_(2) S (g) rarr CuS(s) + 2 2H^(o+)`

A

9.55 of `CuS` is produced.

B

The concentratikon of `H^(o+)` ions is `0.2 M`

C

The concentration of `H^(o+)` ions is `0.1 M`

D

`95.5 g CuS` is produced

Text Solution

Verified by Experts

The correct Answer is:
A, B
Mol of `Cu^(2+) = 1.0 L xx 0.1 M = 0.1 "mol" Cu^(2+) = 0.1 xx 2 "mol" H^(o+)`
a. Weight of `CuS = 0.1 xx 95.5 = 9.5 g`
b. Concentration of `H^(o+)` = `(0.2 "mol")/(1.0 L) = 0.2 M`
(c ) and (d) are wrong.
