HW Problem 6D. 15

Postby Gisela F Ramirez 2H » Wed Jan 23, 2019 8:31 pm

Calculate the pH of:
a.) 0.19M NH4Cl (aq)
b.) 0.055M AlCl3 (aq)

I am stumped on this question. How do I go about it since they did not give me the Ka value?

In the homework problems they sometimes do not put the Ka value in the question but they instead expect you to refer to a chart in the reading that lists many of the Ka values.
