Salt is incredibly important, and really useful. A common myth is that Roman soldiers were partly paid in salt, resulting in the word “salary” We need to keep levels of salt in our body the same or it can be fatal. It has many different uses, such as on our fish and chips, or for deicing roads. Many industrial processes need salt. More unusual uses can also be found, such as relieving bee stings or testing how fresh an egg is. It can even be used to stop trainers smelling!
GCSE scientists – you need to be able to explain which salts are made when metal and non metal ions form salts through ionic bonding. You also need to be able to describe the structure and properties of these ionic compounds. In addition you must explain why they have these properties. If you need some help, check out our new “How to work with Ionic Bonding:Part 2” guide. It covers these areas, and includes questions for you to try, along with answers to check your understanding.
