Calculate the pH of (a) 0.19 m NH4Cl(aq); (b) 0.055 m

How do we do part b of this question? What will be the dissociation reaction?

The dissociation reaction is AlCl3 + H2O --> Al(OH)3 + HCl. H2O would always be added because it is a solvent and then with that you could figure out the products. The equation above is not balanced and then HCl would dissolve into H+ and Cl- and you would use that to calculate the pH.
