Is A correct?
Answered by DrBob222
CH3COOH = HAc
HAc is a weak acid; therefore, it has an ionization constant, Ka. Look up that Ka value, write the Ka expression, and assuming a value of, say, 0.1M or HAc initially, you can calculate the three species and know the answer.
.........HAc + H2O <==> H3O^+ + Ac^-
I........0.1.............0.......0
C........-x..............x.......x
E......0.1-x.............x.......x

Where I is initial, C is change, and E is equilibrium.

Post your work if you get stuck.

Yes, A is correct but do you know WHY it is correct or are you guessing?
