In one part of this experiment you undertake a titration. Read the burette shown below (meniscus is in red) to the correct number of decimal places.

At the start of the titration of CH₃COOH with NaOH (titrant) the major solute species in the beaker (see below) is/are….

Note: titrations generally involve conical flasks not beakers.

Below is a titration curve. By considering the pH at the equivalence point (steepest gradient on curve), determine which of the following titrations this curve best describes.

When a strong acid reacts with a weak base the pH of the equivalence point is…….

In an acid/base titration, for a monoprotic acid, the point at which the n(acid) = n(base) is the …….

When a strong acid reacts with a strong base the pH of the equivalence point is…….

At the equivalence point of the titration of CH₃COOH, with NaOH (titrant) the major solute species in the beaker (see below) is/are….

A Brønsted acid is ...

An acid/base indicator has a protonated form, InH, and a deprotonated form, In^-, that have different colours. An indicator reacts according to the reaction below. In which form will the indicator exist under acidic conditions?
