CHM 120 Lecture Notes - Lecture 16: Nitrous Acid, Unified Atomic Mass Unit, Bromic Acid
Document Summary
Acids: are molecular compounds that produce hydrogen ions (h+) when dissolved in water. Acids are composed hydrogen (written first) and one or more nonmetals (written second) Hcl (ag) hydrochloric acid (present in stomach fluids) Classification of acids: binary acids- contains hydrogen and a nonmetal, oxyacids- contain hydrogen, a nonmental and oxyanion (polyatomic ion with oxygen) Rule: hyrdro +base name of nonmetal + ic +acid. Ex) h2s (ag) hydrosulfuric acid *exception you take whole name. The number of hydrogen ion = to charge of oxyanion ion (charge neutral) The names of oxyacids containg oxyanions ending with ite: Rule 1: base name of oxyanion +ous + acid. Ex) no2- nitrite hno2 (ag) - nitrous acid (oxyacid) Ex) so2- - sulfite h2so3 (ag)- sulfurous acid (exception with sulfur) (oxyacid) The names of oxyacids containing oxyanions ending with ate: Rule 2: base name of oxyanion + ic _ acid. Ex) no3- - nitrate hno3(aq) nitric acid (oxyacid)
