Carolina® Chemistry Topic Bundles: Acids, Bases, and pH

$252.00

Description

Streamline your unit on acids, bases, and pH measurement plus save time and money with this bundle of 3 comprehensive Carolina chemistry kits. The bundle includes 1 demonstration kit, Carolina Chemonstrations®: Rainbow Indicators (item #840333), and 2 classroom kits, Carolina ChemKits®: Understanding pH Measurement (item #840667) and Carolina ChemKits®: Exploring Acids and Bases (item #840665). Demonstration kit materials are sufficient for 5 demonstrations; classroom kit materials are sufficient for 30 students working in groups of 3.

Start with a colorful introduction to pH indicators with Carolina Chemonstrations®: Rainbow Indicators (item #840333). Amaze your students as you add colorless solutions to seemingly empty beakers and produce a rainbow of colors. Students make predictions about the results based on prior knowledge, then after the demo they construct an explanation of their observations. Students answer big-picture questions that ensure their understanding of the underlying concepts to wrap up this mesmerizing chemical demonstration. The demonstration requires approximately 5 minutes of classroom time; materials are sufficient for 5 demonstrations.

Students get started with hands-on inquiry exploration of pH with Carolina ChemKits®: Understanding pH Measurement (item #840667). Students learn about the use of red and blue litmus paper, universal pH paper, and common liquid indicators. They determine the pH of known and unknown acids and bases, measure the pH of various household products, and demonstrate that carbon dioxide in water is acidic. The kit contains multiple extension activities, including calculating the Ka of a weak acid, how to accurately measure the pH of rain, and how to make litmus paper. Activities require approximately 90 minutes of classroom time and can be completed over multiple class periods. Kit materials are sufficient for 30 students working in groups of 3.

Students explore the fundamental properties of acids and bases with Carolina ChemKits®: Exploring Acids and Bases (item #840665). They use indicators to test for acids and bases, combine acids with metals and carbonates to produce hydrogen and carbon dioxide gas, and titrate vinegar to determine the molar concentration of acetic acid. Students also explore strong and weak acids through the acids' reactions with metals. Activities require approximately 80 minutes of classroom time and can be completed over multiple class periods. Kit materials are sufficient for 30 students working in groups of 3.
