Which is more...

Question

Which is more basic $M g (O H)_{2}$ or $A l (O H)_{3}$ ?

Open in App

Solution

$A l (O H)_{3}$ is more basic than $B e (O H)_{2}$ since the size of Al atom is more than that of Be, the force of attraction between $A l^{3 +}$ ion and $O H^{-}$ will be less than that between $B e^{2 +}$ and $O H^{-}$ ion. Hence Al can loose the $O H^{-}$ ion easily than by Be.
