In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this...
When titrating a weak acid with a strong base, I know that the pH at the equivalence point will be higher than pH 7, since the strong base releases all its OH- ions while the weak acid only disassociates partially. But here is my problem: wouldn't the OH- and H+ form water, and...
Another typical calculation from a titration involves determining the pH of the equivalence point. The weak acid, acetic acid, and the strong base , sodium hydroxide, will react to form water and the salt, sodium acetate. Hydrogen ions (H+) from acetic acid react with the hydroxide ions (...
