Need a couple of good high school chemistry sites where I can print worksheets . . .

[HootOwl]

My 16-year-old need LOTS of additional practice with her chemistry lessons from school. She is now working on calculating pH and pOH solutions, and this is where we need to focus.

I use Edhelper with my younger kids to print off worksheets for review, but I don't currently subscribe to the high school content. Are their high-school materials quality enough to help? If not, do you have a couple of other sites to recommend.

Right now, we're primarily looking to print off worksheets that she can do on her own. Since I don't have an extensive background in Chemistry, I would need to have materials with a teacher answer key.

Hope you can help!

Thanks,
Lisa

Here's a great chemistry website:

Among the things that I saw on it is the following worksheet:

Answers (no explanation) are on the last page. These will give your student some extra practice.
