this question was in my discussion section a while ago and i still do not understand.
find the pH of a .055 M solution AlCl3
I was just rly confused bc in the solutions manual it changes to Al(H2O)6 3+. can someone explain why that is?

Re: pH of .005 M AlCl3
Al3+ forms coordinate covalent bonds with H2O in solution, yielding the coordinate covalent compound Al(H2O)6 3+, which will then lose protons from its coordinated H2O to free-floating H2O molecules, forming H3O+

Yeah, it exists as a complex in solution that loses a proton to form [Al(H2O)5)OH)]^2+ + H3O^+

Re: pH of .005 M AlCl3
Al has a charge of 3+ and is able to form a coordination compound. When it binds to water, it weakens the existed OH bond in water which leads to an H+ being released.
