Titration Curves - Help needed I really need some help in this, I don't understand how to make a titration curve. I have 50ml of a 0.1 M solution of formic acid with a 0.1 M solution of NaOH. I know that the pKa of the formic acid is 3.74 but i don't know how to get the pH or H+. I've hit a wall and my brain is fried from trying to figure it out. Thanks.
