Acids: Acids are chemicals which can dissociate in water to yield hydrogen ions. There are two types of acids which are strong acids and weak acids. Strong acids dissociate completely and weak acids only dissociate partially. Answer and Explanation:1 ...
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.
