Acid–Base Titration. The concentration of a weak acid or a weak base in water is difficult – if not impossible – to measure directly.. But we can calculate the concentration from the results of titration.. 17 Acids & Bases.

The term titrimetric analysis refers to quantitative chemical analysis carried out . Acid-base chemistry is highly diverse, encompassing not only the traditional H. . /OH. –. chemistry that characterizes aqueous solutions but also proton transfer in non-aqueous systems, and aprotic solvent systems and metal . Mullany. Chemistry. Agenda. We are going to learn. Properties of acids and . bases. Acid and base nomenclature. What is an acid and what is a base?. What is another way of classifying an acid and a base?. Demonstrate understanding of equilibrium principles in aqueous systems. Aqueous systems are limited to those involving sparingly soluble ionic solids and acidic and basic solutions (in which proton transfer occurs). .
