Why is m-cresol soluble in Bicarbonate Solution?

Well, what is $\text{m-cresol}$?
And thus m-cresol is a PHENOL derivative, that is much more acidic than an aliphatic alcohol. Its acidity, $p {K}_{a} = 10.01$, is slightly LESS than that of phenol, $p {K}_{a} = 9.95$ … but still high for a carbon acid.
$m - {C}_{6} {H}_{5} \left(C {H}_{3}\right) O H + H C {O}_{3}^{-} \rightarrow m - {C}_{6} {H}_{5} \left(C {H}_{3}\right) {O}^{-} + {H}_{2} O + C {O}_{2} \left(g\right) \uparrow$
