Enough of a monoprotic acid is dissolved in water to produce a 0.0136 m solution. the ph of the resulting solution is 2.45. calculate the ka for the acid.

Explanation:

initially conc.         c                              0         0

At eqm.                  

The expression for dissociation constant is,

And,

Now put all the given values in this expression, we get

i think slash and
