# The strong bases

## Definition

A base $B$ is strong if its proton exchange reaction with water (dissociation) producing the corresponding acide $HB$ $B$ $+$ $H_2O$ $\rightarrow$ $OH^-$ $+$ $HB$ is complete.

- Note the single arrow reaction     $\rightarrow$ - Eventual charges of $HB$ and $B$ are not shown in this general formula

.

## Usual strong bases

Strong bases:
 $NH_2^-$ amide $RO^-$ alcoolate (R = methyl, ethyl..) $O^{2-}$ oxide (from soluble oxides)
