Question

a soluble salt containg four different non metallic elements ​

Answer 1

Answer:

A double salt is a salt that contains more than one cation or more than one anion. Examples of double salts include alums (with the general formula MIMIII[SO4]2·12H2O) and Tutton's salts (with the general formula [MI]2MII[SO4]2·6H2O).[1] Other examples include potassium sodium tartrate, ammonium iron(II) sulfate (Mohr's salt), and bromlite. The fluorocarbonates contain fluoride and carbonate anions. Many coordination complexes form double salts
