Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.

Description

Many people think that all acids are the same. Often times when students hear the phrases strong acid and weak acid they will confuse these concepts with high/low concentration of the acid. This demonstration kit has been designed to visualize the differences between strong and weak acids. Activities include demonstrations of differences in pH values, effect of conjugate base and vigor of reactions. This kit contains an easy to follow teachers manual and enough materials to perform 7 demonstrations.
