Unformatted text preview: + cation and a polyatomic anion For binary acids, the name will depend on if it is dissolved in water, so be careful. Naming Binary Acids (if in water) Write a hydro prefix Write the word acid at the end of the name Acids are molecular compounds. If polyatomic ion name ends in –ate, then change ending to –ic suffix, For examples: HF is hydrogen fluoride and H2S is hydrogen sulfide. Is H2O hydrogen oxide? This naming system is only used for binary acids if they are NOT dissolved in water. Naming Oxyacids e.g. HNO3 is nitric acid (NO3- is nitrate). If polyatomic ion name ends in –ite, then change ending to –ous suffix. Formula generally start with H, e.g., HCl, H2Se However, they have some properties similar to ionic substances and therefore have unique naming rules. Binary acids (hydrogen + one nonmetal) are named as if they were ionic with H+ acting as a type I metal. Change ending on nonmetal name to –ic Binary Acids (not in water) Follow with the nonmetal name Binary acids have different names when dissolved in water. For a compound dissolved in water (aq) is written after the...
