This summative assessment targets all aspects of a traditional unit on Acids and Bases. It was designed for an honors-level Chemistry class but it can easily be modified for all levels. Be sure to check out other original creations by MJ.
I'm sorry you feel that it was a "waste of money", but the product description/homepage indicates that it's four pages long, with thumbnails shown for all pages. I hope the test itself was not a waste. An answer key alone does not make the test a satisfactory assessment.
