MgCl2 + 2NaOH  → Mg(OH)2 + 2NaCl
 No of Millimoles (t0)   10         20 0 0
No of Millimoles (t)    0       0 10
 
 
 
So, [Mg2+] = 10/200 = 1/20
 
Ksp Mg(OH)2 = S[Mg2+] × S(OH-) = {1/20} × {4 (OH-)2}  
 
 2 (OH-) = square root of 1.2 cross times 10 to the power of negative 11 end exponent cross times 20 end root = square root of 2.4 cross times 10 to the power of negative 10 end exponent end root = 1.55 cross times 10 to the power of negative 5 end exponent 
(OH-) = Near to 10-5
