# What is the pH of an aqueous solution of sodium carbonate?

$C {O}_{3}^{2 -} + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s H C {O}_{3}^{-} + H {O}^{-}$
As bases go, carbonate ion is fairly weak. Nevertheless a solution of sodium carbonate would cause hydrolysis, and give a $p H > 7$, and thus a basic solution.
