Jul 30, 2015 - Viva Questions 1. What is a weak acid? Weak acid is a weak electrolyte, which ionises incompletely in aqueous solution. 2. What is PKa of a weak acid? PKa is a modern method of expressing the strength of weak of acids. It is mathematic
Learning Targets: I can explain how an acid can be weak in terms of "dissociation equilibrium". I can write the the acid dissociation constant, K a, for a weak acid. I can use an ICE table to solve for [H +] or K a for an aqueous solution of a weak acid. I can calculate the pH of a weak acid using an ICE table. (more) See More
