  1. Binary Acids By: Moe Abdo, Narakan & Park

  2. Binary Acids • Acids are substances that produces one or more hydrogen ions (H+) when dissolved in water. • (aq) presents its an acid • Binary acids those acids that are composed of only two elements. • They are certain molecular compounds in which hydrogen is combined with other nonmetallic atom yield acidic solution when dissolved in water. • The weaker the bond between hydrogen and the non-metal the stronger the acid

  3. Naming • In naming acids we use the prefix hydro followed by the root of the non-metalmodified with (ic) ending, then followed by the word acid. • Hydro + Stem of (x)(ic) + Word (Acid)

  4. ExamplesHydro + Stem of (x)(ic) + Word (Acid) • HF(aq) hydro+fluor+icacid Hydrofluoric Acid • Hydrochloric Acid Hydro+Chlor+icacid Hydro= Hydrogen, Chlor= Chlorine, HCl(aq) • HBr(aq) Hydro+Brom+icacid Hydrobromic Acid

  5. Exceptions • H2S(aq) Hydro+sulfur+icacid For the non-metal we used the element name not the stem of the name. Hydrosulfuric Acid

  6. Exceptions • HI(aq) Hydr+iod+icacid This time the letter (O) was dropped from the word hydro. Hydriodic Acid

  7. Practice Name the following Binary acids: • NH3 • CH4 • H2Se • PH3 • AtH

  8. Name the following Hydrosulfuric Acid Hydronitric Acid Hydrochloric Acid Hydroxic Acid Hydrofluoric Acid

  9. Answers Hydronitric Acid Hydrocarbonic Acid Hydroselenic Acid Hydrophospharic Acid Hydroastatic Acid ________________________________________ H2S NH3 HCl HO2 HF
