Homework Answers
ACid is CH3COOH , acetic acid
b) Base is Ca(OH)2 , calcium hydroxide
c) overall ionic equation is
Ca(OH)2 (s) +2 CH3COO- (aq) + 2 H+(aq) ------> Ca+2(aq) +
2CH3COO-(aq) + 2H2O(l)
d)
The net ionic equation is obtained by removing the spectator ions
from total ionic equation which are present on both sides.
Ca(OH)2 (s) + 2 H+(aq) ------> Ca+2(aq) + 2H2O(l)
