back again and I cant afford to get these wrong. I would appreciate some help.
When 25.00 mL of HNO3 are titrated with Sr(OH)2, 58.4mL of a .218M solution are required.
a. What is the pH of HNO3 before titration?
b. What is the pH at the equivalence point?
Ascorbic acid, HC6H7O3, also known at vitamin c is a weak acid. A solution of ascorbic acid is prepared by dissolving 2.00 grams in enough water to make 100.0 ml of solution. The resulting solution has a pH of 2.54. what is the Ka for the ascorbic acid.?
