It has an incredibly high pH, and anything above 7 on the pH scale is a base

Step-by-step explanation:

Bases are those substance which releases hydroxide ions in aqueous solution when dissolved in water.


BOH(aq)\rightarrow B^+(aq)+OH^-(aq)

As we can see that in formula of aluminium hydroxide , there are 3 hydroxide ions attached to single aluminum ion. So, when we will dissolve the aluminum hydroxide in water it will give aluminum ions and hydroxide ions in its solution.


Al(OH)_3(aq)\rightarrow Al^(3+)(aq)+3OH^-(aq)
