1. A .1500 g sample of pure ZnCl2 * nH20 was placed on an ion exchange column in the H+ form. The h+ released in the eluat required 16.89 mL of .1024 M NaOH to reach a phenolpthalein end point. Calcuate the percent sinc in the sample.
2. calculate the value of n for the data in question 1
3. If a .135 g sample of NACL was placed on an ion exchange column in the h+ form and the eluate titrated with .1231 M NaOH, what volume of the NaOH solution would be required to reach a phenolpthalein end point?
I have absouletely no idea how to do this, i really need an explination
