Chemistry Demonstration, War of the Acids

Chemistry Demonstration, War of the Acids

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.
