Millimoles of calcium hydroxyide required to produce 100 mL of the aqueous solution of pH 12 is x x 10 -1 . The value of x is_______(Nearest integer).
Assume complete dissociation.
Text Solution
Verified by ExpertsThe correct answer is:
5
(5)
pH= 12
[H + ] = 10 -12 M
[OH - ] = 10 2 M
[Ca(OH) 2 ] = 5 x 10 -3 M
milli moles of Ca(OH) 2 = 5x10 -1
Ans. = 5
