Acids(not the kind that Madison does on the weekend) • Binary Acids= hydrogen + 5 A, 6 A, 7 A – Naming Binary acids= hydro + root of the second element + ic and acid – Writing formulas= balancing charges with hydrogen being +1. – HCl, HBr, H 2 S

Oxyacids • Hydrogen + polyatomic ion • Naming= If polyatomic ends in –ate, drop it add -ic and acid. (NO HYDRO) – If polyatomic ends in –ite, drop it add –ous and acid. – HNO 3 or HNO 2 – HCl. O 3
