Kemtec™ AP Chemistry Kits: Preparing Buffer Solutions and Determining Their Properties

Description

Includes

Sodium Hydroxide, 12.0N; Hydrochloric Acid, 12M; Acetic Acid, 25%v/v, 100ML; Ammonium Hydroxide, 20%v/v 100mL; Sodium Phosphate Monobasic; Sodium Phosphate Dibasic; Ammonium Chloride, ACS; Sodium Acetate, Trihydrate, ACS

Requires

pH meter, glassware

After being assigned one of the three buffer systems, pH, and component acids, bases or conjugates, students construct a buffer and test it based on their own calculations. Students compare the pH changes of their buffer to those of distilled water and other solutions.

• Minimal prep time required
• Instructor's manual features background material, easy to follow stepwise protocols, assessment questions, sample data, modeled calculations, and an answer key
• Kit designed to exceed 2013 AP Next Generation National Standards
• Meets AP Science Practices 4 & 7
• Targets Grades: 10-14
• Accommodates 24 Students Working in Groups of two

Kemtec AP kits are compatible with optional data collection and simulations using TI-Nspire handhelds and software. Free activities can be found at www.fisheredu.com/TI.
