PH scale resources

Students answer two multiple-choice questions on pH.

Explain how to test if a solution is an acid or not, and describe and explain what happens if rusty nails are put in an acid. Assessment focus: acid reactions.

Task: Students read a pH scale to determine how it shows the increasing strength of an acid and a base solution and decide from different pH products what the effect would be on an acidic soil. Assessment focus: interpreting a pH scale.

Task: Using the given pH, classify 10 common substances as acidic, basic, or neutral. Assessment focus: knowledge of the pH scale

Students use a table of some substances and their pHs to answer four questions.

Students draw up a table to illustrate results of how indicators change when placed into four different liquids.
