A buffer solution is an aqueous solution that can resist significant changes in pH when small amounts of an acid or a base are added. It is essential in various laboratory and industrial processes ...

The pH scale is an essential tool in chemistry, biology, and various other scientific fields. It measures the acidity or alkalinity of a solution. If you’ve ever wondered how to calculate pH from ...

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 ...

This lab includes the complete titration procedure used to investigate how well a buffer resists changes in pH. Prepare a buffer solution by accurately calculating and measuring the required amounts ...

Watch this video to see how a salt can be produced in the lab by neutralising sulfuric acid with a metal carbonate, in this case copper carbonate. Here are some ways neutralisation is used: Farmers ...

The pH scale measures how acidic or alkaline a solution is. It ranges between 0 and 14. Acids have a pH of less than 7. Alkalis ( or bases ) have a pH of over 7. pH 7 is neutral. pH is measured using ...
