pH of a weak acid solution
In this video we calculate the pH of a solution that contains a weak acid.
pKa and pKb relationship
In the following video we explore the relationship between the pKa of a weak acid and the pKb of its conjugate base.
The Born-Haber Cycle is challenging for most candidates. Clearing up the solution process for these subject can give you some critical points on the exam.
