Write the balanced equations of the following ions which are given on the left side .
Make a copy for yourself.
Paste your photos in there, only from your group please, not from some other group.
Write the chemical equation for each reaction, if there was a reaction. If not, just write “No reaction.”
Identify the anion in your unknown.
Paste some photos of your tests on the unknown, and explain in three sentences or less how you know that you are correct.
Post a photo of the result of your anion test, and write a chemical equation that explains the product, for each
box. If there was no reaction, then write, “No reaction,” but still post the photo.
For reactions that formed a gas, if your photo does not show the bubbles then please just type underneath
your photo, “bubbles escaped.” Thank you.

Skip this equation. The one on Google is supposed
to be blue, but that’s with phosphate, not hydrogen
phosphate. Thanks.
