Hey everyone, we're asked to classify aluminum with a plus three charge as an acidic or neutral caddy on if it is an acidic cat. Ian, Wright, a chemical equation showing how it acts as an acid in an Aquarius solution. So we know that aluminum with a plus three charge is a main group metal catalon and main group metal cat ions with a charge of greater than plus two are acidic. So since aluminum has that plus three charge, we would categorize it as an acidic caddy on. So now that we've established that this is an acidic carry on, Let's go ahead and write a chemical equation showing how it acts as an acid. So we have our aluminum and this is going to react with water. Now when these two react, aluminum is going to act as a lewis acid and it's going to accept the lone pair from our Lewis base, which is going to be our hydroxide ion. So we have aluminum hydroxide And this is going to have a plus two charge. And next we're going to have that lone proton. Now we need to make sure everything is completely balanced out and it looks like it is. So this would be our final balanced chemical equation. Now, I hope this made sense. And let us know if you have any questions
