Salts

Hey,

I am a student from Norwich and for my chemistry I need to know about salts. I think this would be helpfull for me to know for my next exam. If you could help me I will be thank full.

When you have to choose 3 different salts (but don’t choose a carbonate or hydrogencarbonate, also called bicarbonate – not easy to prepare), one with a medical application, one used in agriculture and one used in the kitchen, which salts would it be and what is the use for exactly?

Can you also include a one or two lines to explain why it is suitable for the use stated?
 
Also for each salt, can you describe a safe method that could be used to make a small sample of it with the materials, equipment and a quick small procedure?

Thanks alot,

Elena

The salt for in the kitchen seems obvious: kitchen salt (NaCl). You can make it bij destilling seawater. But there is also salt for the dishwasher.
In agriculture, there are different salts, to enrich the land or for cows to lick.
In medicine there is for example  AgNO3 , that has different applications.
