Naming Acids. Acids. Homogeneous mixture that produce hydronium ion (H 3 O + ) The formulas begin with H and end with ( aq ) *( aq ) = aqueous, meaning “dissolved in water” (Ex) HCl ( aq ) , H 2 SO 4 ( aq ) Naming depends if the acid has oxygen or not (Ex) HCl ( aq ) , H 2 SO 4 ( aq ).

Acids • Homogeneous mixture that produce hydronium ion (H3O+) • The formulas begin with H and end with (aq) *(aq) = aqueous, meaning “dissolved in water” (Ex) HCl(aq), H2SO4(aq) • Naming depends if the acid has oxygen or not (Ex) HCl(aq), H2SO4(aq)
Naming Acids that Do Not ContainOxygen 1. Read the hydrogen as “hydro” 2. Modify the second’s element name with “ic acid” (Ex) HCl(aq) : hydro HCl(aq) : hydrochloric acid (Ex) H2S(aq): hydrosulfuric acid ** fluoric; iodic, bromic, selenic, cyanic,
Naming Acids that Contain Oxygen • Don’t read the hydrogen • If the polyatomic anion’s name ends with “ate”, change it to “ic acid” (Ex) H2SO4(aq): sulfuric acid 3. If the polyatomic anion’s name ends with “ite”, change it to “ous acid” (Ex) H2SO3(aq): sulfurous acid
Practices • Name the acids. 1. HNO2(aq) 2. H2 CO3(aq) 3. HF(aq)
Practices • Write the formulas 1. nitric acid 2. hypochlorous acid 3. acetic acid 4. hydroselenic acid
