Homework Answers
9) The resulting solution is basic, since the acid is weak and the base is strong.
10) Option A. Since both substances are strong and a buffer is not created.
11) A) Neutral solution, as it does not hydrolyse.
B) Neutral solution, because it does not hydrolyze.
C) Basic solution, because it hydrolyzes:
CH3CO2- + H2O = HCH3CO2 + OH-
If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
