Determination of dissociation constant of weak acid using pH meter [PDF]
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 mathematically expressed as PKa = -log10 ka. Where Ka is the dissociation ...
