# Arrhenius Acids and Bases

## Key Questions

The specie which donate $\left[O {H}^{-}\right]$thus increase its concentration in the solution , is an Arrhenius Base.
The specie which gives $\left[O {H}^{-}\right]$ions on making its aqueous solution is an Arrhenius Base.
For Eg : $N a O H \left(a q\right) \rightarrow N {a}^{+} + O {H}^{-}$
