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….
