Students explore the differences between acids and bases. In groups, students perform science experiments to demonstrate the properties and reactions of particular acids and bases. They dilute a solution from a concentrate, perform a neutralization reaction, use the titration technique to analyze the solution and determine if the solution is an acid or base. Full Review »
