1. phenolphthalein is a weak acid represented by the formula HIn. In its molecular form, it is colorless. In its ionized form, it is magenta. write the equation for the ionization of phenolphthalein that results from reacting it with water. include the colors underneath the equation.

1a. if an acid is added to phenolphthalein in what direction will the reaction shift? why?

1b. if a base is added, in what direction will the reaction shift? why?
