The ionisation constant of ammonia at 29...

The ionisation constant of ammonia at 298K is `1.8xx10^(-5)` Calculate (a) the degree of ionisation, (b) concentration of `OH^-` ions in 0.01(M) aqueous solution of ammonia.

Text Solution

Verified by Experts

`[H_3O^+]=propc` or `-log_(10)[H_3O^+]=-log(propc)`
or, pH=-log`(propxx0.1)` or `3.37=-log(propxx0.01)`
or, `propxx0.01=4.26xx10^(-4)" ":.prop=0.0426` i.e. 4.26%`
