Almost Done Naming… Gasses and Acid Salts
Noble Gases (monoatomic) Example: He – helium gas Argon gas - Ar Diatomic gases (two atoms) I2 – iodine gas Br2 – bromine gas Cl2 – chlorine gas F2 -– fluorine gas O2 – oxygen gas N2 – nitrogen gas H2– hydrogen gas IBring Clay For Our New House Naming Gases
Acid Salts • An acid salt is formed when only some of the hydrogens are replaced by a metal • Acid salts are named the same as neutral salts, however, the remianing acid hydrogen atom(s) are indicated by the word “hydrogen” (or dihydrogen, etc. as appropriate) inserted between the names of the cation and the anion. • For example: Na + H2SO4NaHSO4 (sodium hydrogen sulfate) • Ca + H3PO4 Ca(H2PO4)2 (calcium dihydrogen phosphate)
Practice Problems • Potassium hydrogen sulfate • LiHSO4 • Li2HPO4 • ammonium hydrogen carbonate • sodium dihydrogen phosphate KHSO4 Lithium hydrogen sulfate Lithium hydrogen phosphate NH4HCO3 NaH2PO4
