Kemtec™ AP™ Chemistry Kits:Identifying Weak Acids by pKa

Description

Includes

Oxalic Acid, 10g; Potassium Acid Phthalate, ACS; Potassium Bisulfate, Reagent; Benzoic Acid, 10g; 2 bottles Sodium Hydroxide, 1.0N; Phenolphthalein Ind Soln, 30mL

Requires

pH meter, Burets, pipets and volumetric flasks

Students perform titrations on weak acids while measuring pH, perform qualitative analysis by determining pKa values of acids, perform quantitative analysis by calculating molar masses, confirm the identities of weak acids, and derive and use the Henderson-Hasselbalch equation.

Features four different weak acid solids: three monoprotic, one diprotic.

• Ideal for two 45-minute lab periods
• 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 Chemistry Science Practices 2, 5 & 6
• 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.
