Introduction to Acid–Base
Acid–Base Test Kit I—
Properties of Acids and Bases— Student Laboratory Kit
Students test acids and bases with litmus paper and phenolphthalein indicator. Examine how pH is related to the strength
of an acid or base. Observe the reaction of carbonates and compare the reactivity of different metals with acids. Test the pH of various household products. All materials are provided. Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students in pairs.

Several titrations can be performed during one class period with surprisingly good results. Students determine the percentage of acetic acid in household vinegar by titrat- ing the vinegar with a sodium hydroxide solution of known concentration. The indi- cator phenolphthalein will produce a pink endpoint. Instructions include step-by-step explanations of the calculations. All materials are included. Complete for 30 students work- ing in pairs.
