Suppose you add 20 drops of 0.2M NaOH to 17 drops of 0.2M HCl.  Phenolphthalein has been added to the HCl.  What color do you suspect the resulting solution will be?  Why?  I think that I need to find the pH, because phenolphthalein turns pink at pHs 7-10, and NaOH is a base and HCl is an acid.

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
