The ka of an acid is 1.3 x 10^–7. based on the ka and its relationship with kw, what is the value of kb? use kakb=kw

1.3 x 10^–21
7.7 x 10^–15
1.3 x 10^–14
7.7 x 10^–8

Answer : The value of is,

Explanation :

As we are given :

As we know that,

where,

= dissociation constant of an acid =

= dissociation constant of a base = ?

= dissociation constant of water =

Now put all the given values in the above expression, we get the dissociation constant of a base.

Therefore, the value of is,
