Item 14 Acid refers to any molecule that is able to dissociate in water to form H (aq), which mean acids must contain at least one hydrogen atom in their formula unit. There are six strong acids (containing strongly acidic hydrogen atoms), which are acids that completely dissociate in water (HC1, HBr, HI, 3, HClO and H2SO4). All other acids, which partially dissociate, are considered weak acids (containing weakly acidic hydrogen atoms). Acids are generally categorized into one of the two following groups: binary acids and oxyacids. A binary acid is simply composed of two elements, which are hydrogen and a nonmetal. Oxyacids are composed of at least one hydrogen, one metal or nonmetal, and one oxygen. The names of binary acids are based on their chemical formula, and the following procedure demonstrates how hydrochloric acid is derived from HCl: hydro (prefix) root name of nonmetal ic ending acid hydro chlor acid ic Note that the -ine ending is dropped from the element name to form the root of the nonmetal chlorine before adding the -ic ending. Elements have various endings that are dropped before adding the -icsuffix, which can include -ogen, ium, -on, -ine, -orus, etc. Part A Use the naming conventions to complete the following formula-name pairs of binary acids. Match the acid names and chemical formulas in the left column to the appropriate blanks in the chemical formulas and acid names on the right. Make certain each acid name and chemical formula is complete before submitting your answer.
