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

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.
