Concentration of NH(4)Cl and NH(4)OH in ...

Concentration of `NH_(4)Cl` and `NH_(4)OH` in a buffer solution are in the ratio of `1 : 10`, Kb for `NH_(4)OH` is `10^(-10)`. The pH of the buffer is

A

`4`

B

`5`

C

`9`

D

`11`

Text Solution

Verified by Experts

The correct Answer is:
B

`P^(OH) = 10 + "log" (1)/(10)`
`P^(OH) = 9 , P_(H) = 5`

A certain buffer solution contains equal concentration of X^- and HX. The K_b for X^- is 10^-10 . The pH of the buffer is:

A basic buffer contains 0.8 mole of NH_(4)Cl and 0.2 mole of NH_(4)OH for litre of a solution the K_(b) of base is 1.8 xx 10^(-5) . Then the P^(H) of the buffer solution is (log 1.8 = 0.2553)

Consider the following statement and select correct option: (I) K_(sp) of Fe(OH)_(3) in aqueous solution is 3.8xx10^(-38) at 298 K. The concentration of Fe^(+) will increase when [H^(+)] ion concentration decreases. (II) In a mixture of NH_(4)Cl and NH_(4)OH in water, a further amountof NH_(4)Cl is added. The pH of the mixture will decreases. (III) An aqueous solution of each of the following salt (NH_(4)I,HCOOK) will be basic, acidic respectively.
