[attachment id=0 msg=3652] Can you please walk me through how to calculate this and also what the equation would be?

AlCl₃ is a salt of strong acid HCl and weak base Al(OH)₃. Al³⁺ is strong conjugate acid of weak base and Cl^- is the weak conjugate base of strong acid.
It means pH is controlled by Al³⁺ and solution has pH less than 7.

Al³⁺ is very small and highly charged species which can have expanded octet in its complexes. In water it can make coordinate bonds with 6 H₂O molecules and then ionizes to give H₃O ⁺ ions
Al³⁺ + 6H₂O ----->    Al(H2O)6 ³⁺      
Al(H₂O)₆ ³⁺ <----> [Al(H2O)5 OH ]^2- + H3O ⁺ 
Ka = 1.4 * 10 ^-5
Make RICE table  and calculate concentration of H₃O ⁺ and pH .
pH = 3.43
