Learn the basics about the pH scale, universal indicator and litmus paper. Indicators tells if something is acidic, alkaline or neutral. Indicators are substances that show different colours when they are in acidic or alkaline conditions. Litmus paper is a simple indicator that tells us whether something is acid or alkali. Litmus is red in acids, and blue in alkalis. It comes as red litmus paper and blue litmus paper. Red litmus paper changes colour from red to blue under alkaline conditions, but no change under acidic conditions. Blue litmus paper changes colour from blue to red under acidic conditions, but no change under alkaline conditions. The pH scale and universal indicator can give more information, telling how acidic or alkaline something is. Universal indicator has many different colour changes and so shows us the pH value of the solution. The pH scale runs from 0 to 14, with 0 being extremely acidic, 7 being neutral and 14 being extremely alkaline.

All living organisms are made up of cells - they are the basic building blocks of life. There are two important categories of cells: plant cells and animal cells. In this video we look at animal cells in more detail. Animal cells are the type of cell that make up our bodies... and the bodies of al
Learn the basics about carbon neutral and biofuels, as a part of environmental chemistry. Coal, oil, natural gas, shale gas and gas from fracking are fossil fuels formed hundreds of millions of years ago from living things that got trapped by layers of sediment before they had time to decompose. H
The way we grow and develop in the womb is controlled by our DNA. Small sections of DNA, called genes, carry the code telling the body how to build itself. Usually this works fine, but sometimes those genes carry mistakes in their code. These mistakes, known as mutations, may have no effect, they ma
