Calculate the solubility (in grams per 1.00×102mL of solution)
of magnesium hydroxide in a solution buffered at pH = 12. Express
your answer using two significant figures. I got S1 = 1.2×10^-8
which is correct but for this part i did not get it "How does this
compare to the solubility of Mg(OH)2 in pure water? "Express your
answer using two significant figures. please solve it i could not
get the answer.
#16.98 Calculate the solubility (in grams per 1.00×102mL of
solution) of magnesium hydroxide in a solution buffered at pH = 12.
g/(1.00×102mL)
B) How does this compare to the solubility of Mg(OH)2 in pure
water?
a) Calculate the solubility (in grams per
1.00×10^2mL of solution) of magnesium hydroxide in a
solution buffered at pH = 12.
S1 = _________________ g/(1.00×10^2mL)
b) Calculate the solubility (in grams per
1.00×10^2mL of solution) of magnesium hydroxide in
pure water.
S = __________________ g/(1.00×10^2mL)
c) How does the solubility of Mg(OH)2 in a buffered solution
compare to the solubility of Mg(OH)2 in pure water?
