Homework Help: chemistry

Posted by ashley on Sunday, February 12, 2012 at 3:17pm.

A student is given 3 beakers:

Beaker 1- 50.0 ml of a solution produced by dissolving 6.00 grams of a weak
monoprotic acid ,HX, in enough water to produce 1 liter of solution.
The empirical formula of HX is CH2O. The solution contains 3 drops
of phenolphthalein.

Beaker 2- A 0.07M solution of the salt NaX. It has a pH of 8.8

Beaker 3 50.0 ml of 0.250M KOH

The contents of beaker 3 is added drop-wise to beaker 1 until a pink color appears and remains for 30 seconds. This takes exactly 20.0 ml of the beaker 3 solution. Identify X and calculate the pH of beaker 1 after the addition of the 20 ml.
