In Lake test of Al 3+ ion, there is formation of coloured floating lake. It is due to the fact that Al ( OH )3, a solid surface (suspension) absorbed litmus colour hence appears as "coloured floating lake."

Q. In Lake test of $A l^{3 +}$ ion, there is formation of coloured floating-lake. It is due to

adsorption of litmus by $H_{2} O$

adsorption of litmus by $A l (O H)_{3}$

adsorption of litmus by $A l (O H)_{4}^{-}$

none of the above.
