WebDec 30, 2024 · When doing a titration, we usually have a solution with a known volume but unknown molarity (the analyte), to which a color indicator (e.g., phenolphthalein) is added.The indicator will change colour when this 1: 1 1:1 1: 1 ratio (governed by its titration curve) is achieved.By adding either an acid or a base with a known molarity (the titrant) …
WebpKa is expressed as a common logarithm (base 10) and not as a natural logarithm (base e). Formula to calculate Ka from pKa. Example: Suppose the pKa is 7. Calculate the Ka. Therefore, the Ka is 10^ -7. This means that this is a strong acid. Share. Tweet. Reddit. Pinterest. Email. Prev Article.
