EXPERIMENT NOTEBOOK

Record and compare

Record readings under different conditions and compare volume with pH. Records last for this page session only.

Observe the initial pH, then record half-equivalence and equivalence.

Assumptions: 25°C, ideal dilute solution, complete HCl dissociation and a single acetic-acid Ka. β excludes water and activity effects. Colours are illustrative.
