Naming Acids & Bases : 

Naming Acids & Bases

Naming Binary Acids : 

Naming Binary Acids Binary acids contain 2 elements Hydrogen is always present Names begin with hydro- prefix and end with –ic suffix The stem of the name (goes between hydro- and –ic) is the stem of the element that combines with hydrogen

Example (Naming Binary Acids) : 

Example (Naming Binary Acids) Hydrogen chloride(g) dissolved in water Hydro- -chlor- -ic Hydrochloric Acid Hydrogen fluoride(g) dissolved in water Hydrofluoric Acid

Naming Ternary Acids & Bases : 

Naming Ternary Acids & Bases Ternary acids have 3 elements 3rd element = Oxygen Stem of name comes from element bonded to H & O Prefix and suffix are determined by the number of Oxygen atoms in each molecule

Slide 5: 

Most common form of a ternary acid is given no prefix and –ic_as a suffix H2SO4 HClO3 HNO3 H3PO4 HBrO3 H2CO3 Sulfuric acid Chloric acid Nitric acid Phosphoric acid Bromic acid Carbonic acid Pause the Presentation and complete the remaining examples

If an acid is formed using the same elements, but has 1 less oxygen, no prefix and suffix is -ous : 

If an acid is formed using the same elements, but has 1 less oxygen, no prefix and suffix is -ous H2SO3 HClO2 HNO2 Sulfurous acid Chlorous acid Nitrous acid Pause the Presentation and complete the remaining examples

If an acid is formed using the same elements, but has 2 less oxygens, prefix is hypo- and suffix is -ous : 

If an acid is formed using the same elements, but has 2 less oxygens, prefix is hypo- and suffix is -ous H3PO2 HBrO H2CO Hypophosphorous acid Hypobromous acid Hypocarbonous acid Pause the Presentation and complete the remaining examples

If an acid is formed using the same elements, but has 1 more oxygen, prefix is per- and suffix is –ic : 

If an acid is formed using the same elements, but has 1 more oxygen, prefix is per- and suffix is –ic HClO4 H2SO5 H2CO4 Perchloric acid Persulfuric acid Percarbonic acid Pause the Presentation and complete the remaining examples

Naming Arrhenius Bases : 

Naming Arrhenius Bases Arrhenius bases = Metallic (positively-charged) ion + Hydroxide (negatively-charged) ion Named by adding the word hydroxide to the name of the positive ion. Ex. – Ca(OH)2  Calcium hydroxide
