When 50.0 mL of 0.300 M
nitric acid and 50.0 mL of
0.150 M calcium hypochlorite are
combined, the pH of the resulting solution will be _________greater
thanequal toless than seven.
1)
concentration of KF = 0.118 M
pH = 7 + 1/2 (pKa + log C)
= 7 +1/2 (3.143 + log 0.118)
pH = 8.11
this solution is basic
2)
Net ionic equation :
H+ + ClO- -----------> HClO
this reaction is = Strong Acid + Weak Base
The extent of this reaction is = 100 %
