Question

6. Concentration CN in 0.1 M HCN is o f
To [Kg = 4x10-10 ] 9 x-si ce
(1)2,5 x 106M (2) 4.5 x 10-6Mint
(3) 6.3 * 10M (4) 9.2 x 10-6 M​

Answer 1

Explanation:

Concertration of HCN solution = 0.1 M

concertration of H+ and CN- = 6.3 × 10^-5

As we know that ,

concertration of CN = concertration of H+

= 6.3 × 10 ^-5
