What are Acids. Bases. and Salts? The Swedish chemist Svante Arrhenius introduced the theory of ionization and used this theory to explain much about the behavior of acids and bases. An Arrhenius acid is defined as an compound that dissociates in aqueous solution to form 1-1 н• (aq) HNOз(aq) HCI (aq) NОз- (aq) t L- ( °' 1,.-) An Arrhenius base is defined as а у comp und that dissociates ГО I e.ions. in aqueous solution to form КОН (aq) ➔ (aq) + (aq) NaOH (aq) ➔ N С. к• + _ ♦ Salts are compounds that dissociate in a�ueous solution releasing neither NaCI (aq) Using the Arrhenius definition, classifiy the fo/lowing examples as acids, bases, or salts: HBr Mg(OH)2 НС! KNO2 HfO4 Ва(ОН)2 НзРО4 нею Аl(ОН)з КС2НзО2 NaCI s А Acids and bases сап a/so Ье identified using ап operational definition. Operational definitions are simply а /ist of properties. ACIDS: taste is а characteristic property of all acids in aqueous solution. Acids react with some metals to produce Because aqueous acid solutions conduct electricity, t are identified as BASES: Acids react with b9ses to produce а and water. Bases tend to taste acids, aqueous basic solutions conduct are identified as S to produce а salt and Bases react with Bases turn Since bases and salts are Binary acids are named us,ng the format: hydro_{root word of second element)_ic acid Ternary acids consist of Name the following acids: НзРОз Н2СОз HF and -ite becomes О t}..5 elements. Do NOT use а prefix. Simply change the ending of the polyatomic ion's name and add the word "acid": -ate becomes
