# Do basic compounds produce OH- ions when dissolved in water?

But they all accept protons ${H}^{+}$ easily. The soluable bases may give off $O {H}^{-}$ ions, or - in the case of basic oxides - they may accept a proton from the water equilibrium ${H}_{2} O r i g h t \le f t h a r p \infty n s {H}^{+} + O {H}^{-}$
In both cases $O {H}^{-}$ will be formed.
Non-soluable bases will need an acid to react, no $O {H}^{-}$ is formed.
