Hi
I am doing a project and need to know some items which contain salts.
E.g - Toothpaste contains sodium fluoride, Fertiliser contains Magnesium Sulphate. Things like that please. Preferably things that you can find around the home but anything will do.
Thanks x

Also, if you know the acid which the salt is made from that would be extremely helpful. Eg Sodium Chlorise is from hydrochloric acid. Thanks again !

It starts off as HCH3COO + NaOH ---> H20 + NaCH3COO
Correct?
And furthermore,
What about Calcium Hydroxide and Acetic Acid?
Ca(OH)2(aq) + HCH3COO(aq) --> CaCH3COO(aq) + H2O(l) is the balanced right??
