Molecule Structure on Reaction Rate?

Mg(OH)2 + 2HCl -> MgCl2 + 2H2O

Al(OH)3 + 3HCl -> AlCl3 + 3H2O

Given that Mg(OH)2 and Al(OH)3 share different cations and that Al(OH)3 has an extra hydroxide ion, how will their reaction rates differ from each other?

    Hopefully I've got this right, but I would assume the extra OH group on the Al(OH)3 reaction would slow things down.

    I'd also expect more reactivity of the Mg with the chlorine since this is further to the left of the periodic table.

    Therefore the Mg(OH)2 will have a faster reaction rate.

    Enjoy :)
