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 ...

Many chemicals can be classified as being acidic, neutral or alkaline by using indicators. The pH scale is used to measure acidity and alkalinity. When an acid is neutralised, it forms a salt. Making ...

We typically hear about the corrosive powers of strong acids, but did you know that strong bases can burn and be just as destructive? Chemically speaking, bases are defined as substances that produce ...
