Making chemical solutions

An important part of Chemistry is the ability to make up solutions of a known concentration. This can sound quite complex, however it doesn't need to be.

The following is some simple instructions that will produce 250m of 1molar concentration of Sodium Chloride

I have made this solution up using pure Sodium Chloride, from a chemical supplier [1], rather than table salt which contains Sodium Ferrocyanide. If you need extra help with this try asking on Science forums [2] as there is a section on there for home chemistry.

I am also on the IRCNow network, where we are starting up a channel to discuss amateur / home science.
