The great chem-mystery
So if we know how much NaOH we have added (the burette readings tell us) then we can calculate how much acetic acid was in the flask. The equation for the
The Common-Ion Effect - College of Science
1 8 x 10-5 = [CH3COO-][H3O+]/[CH3COOH] M = amount of acetic acid that dissociates then X M of H3O+ and CH3COO- ions are formed 1 8 x 10-5 = (X + 2 5)(X)/(0 5 - X) Can we use the shortcut to the quadratic? 0 5M acetic acid / 1 8 x 10-5 = 27777 (which is greater than 100) 1 8 x 10-5 = (X + 2 5)(X)/(0 5 - X) ? (2 5)(X)/(0 5) 9 0 x 10-6 = 2 5X
How do you balance the equation CH3COOH + NaOH?
