Measurement—Super Value Kit
Titration—Student Laboratory Kit
Your students will gain a clear understanding of pH and indicators with this introductory kit. Students explore dramatic color changes when they test and record observations for six indicators in acidic and basic environ- ments. Students also compare strengths of acids and bases. Super Value Kit is complete for 5 classes of 30 students working in pairs. AP7637 | $66.15
Burets, Borosilicate Glass, with
Several titrations can be performed during
one class period with surprisingly good results. Students determine the percentage of acetic acid in household vinegar by titrating the vine- gar with a sodium hydroxide solution of known concentration. The indicator phenolphthalein will produce a pink endpoint. Instructions include step-by-step explanations of the calcu- lations. All materials are included. Complete for 30 students working in pairs.

Acid–Base Test Kit I—Properties of Acids and Bases
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 mate- rials are provided. Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students in pairs. 24-well reaction plates are required and available separately.
