Question

Find out the incorrect order of monoacidic base, diacidic base and triacidic base.

• A. $NaOH,Ca(OH{)}_2,Al(OH{)}_3$
• B. $KOH,Sr(OH{)}_2,Ga(OH{)}_3$
  
• C. $Mg(OH{)}_2,Ca(OH{)}_2,Al(OH{)}_3$
  
• D. $LiOH,Ba(OH{)}_2,Tl(OH{)}_3$

Answer 1

The correct option is C $Mg(OH{)}_2,Ca(OH{)}_2,Al(OH{)}_3$


In metal hydroxide, acidity is defined as the number of replaceable hydroxide ions. $M(OH{)}_n$, n is equal to the acidity of that metal hydroxide.
