Homework Help: chemistry

Posted by john( ignore last post sorry) on Tuesday, June 3, 2008 at 6:19pm.

I am trying to find the solubility of Sodium Acetate by using 0.100 mol Hydroxide(base) and 0.837 mol acetic acid( vinegar).
The theoretical solubility of sodium acetate is 82.3g/100ml at 25C. Doing calculations we would want NAOH concentration of 10.47mol/l to react with the vinegar. Since this is not possible we are going heat up the solution mixed up of acetic acid and Hydroxide until a precipitate( which is sodium acetate) forms to find its solubility.

I know we need a lot less acetic acid but how we know how much we need of NAOH and Acetic acid? Also the temperate it starts precipitating is its solubility at that temp rite? but how do measure the mass(grams)
