Match the coloumns.

	Column I(pH value)		Column II (Solution)
A()	5.0	(P)	pH at which  $Mg{\left(OH\right)}_2$ just start precipitating from $2.0\times {10}^{-3}M-M{g}^{2+}$ solution  $(K_{sp}ofMg{\left(OH\right)}_2=2\times {10}^{-6}{M}^3)$
B)	9.0	(Q)	Maximum pH at which 0.1 mole of $Al{\left(OH\right)}_3$ dissolves completely as $A{l}^{3+}$ in 1 L solution $(K_{sp}ofAl{\left(OH\right)}_3=1\times {10}^{-28}{M}^4)$
C)	12.5	(R)	pH at which 0.1 M- $C{H}_{3}COOH$ dissociates 1000/11%  $(K_{a}ofC{H}_{3}COOH=1.0\times {10}^{-5}M)$
D)	6.0	(S)	pH of $3\times {10}^{-5}$ M-Ca$A_2$  solution ($Ca{A}_2$ dissociates completely in water; $K_{a}ofHA=5\times {10}^{-9}$)
		(T)	The pH of  ${10}^{-5}MNaOH$
