An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

You are expected to use titration data to calculate either the concentration or the volume of a solution. In these calculations, you are always told the concentration and volume of one of the ...

In a titration, sulfuric acid of concentration \(0.1 moll^{-1}\) was added from a burette into a conical flask containing \(20cm^{3}\) of sodium hydroxide solution. The average titre was \(11.2cm^{3}\ ...
