Acid-base reactions

Strong and weak acid-base behaviour, pH, indicator chemistry and buffer solutions are covered in the experiments in this section.

While we are still at an early stage with this website it's probably more useful to look at the page with our complete list of experiments in alphabetical order. See the list on About this website.

We are starting with GCSE-level experiments.

Experiments

• A thermometric titration

  A titration between sodium hydroxide and hydrochloric acid using the accompanying temperature change as a means of determining the end-point.

• The acidic reactions of ethanoic acid

  Students compare the acidic properties of ethanoic acid and hydrochloric acid.

• The part that water plays in acidity

  This experiment shows what part water plays in the characteristic properties of acids.

• pH scale

  A simple experiment to explain the relationship between the numbers on the pH scale.

• Indicators and dry ice: demonstration

  A colourful and spectacular demonstration in which solid carbon dioxide (dry ice) is used to cause a colour change in one or more indicators.

• Ammonia fountain

  This spectacular demonstration highlights the high solubility of ammonia in water. The ammonia is shown to form an alkaline solution.
