What is pH value?
pH expresses the acidity or basicity of a solution. It is a very important parameter that needs to be determined regularly in countless applications and industries. The pH value of a solution can be determined by using an indicator, which is a substance that causes a colour change depending on its pH value. The particular pH value can then be determined from the respective colour reaction.
