Universal indicator is useful for giving an estimated value for the pH of a substance This is one of the tougher topics in year 13 chemistry.  In this post David deals with calculating the pH of strong acids and introduces some neat simulations.  Assumed background knowledge This topic is mostly about equilibria so it is important to understand that concept first. Before tackling this topic make sure you : unders...

Hybrids help by being part electric which makes them more efficient but they still burn hydrocarbons. If you're starting out on  an A level chemistry course take a little time to revise the bits of chemistry below.  You will have performed calculations involving mass changes and you will have studied combustion reactions. In the video I've done a rough calculation to see how much we think we might have reduced our...
