Unformatted text preview: n: Net Acid-Base Reactions • The “driving force” is the formation of water. The is NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(liq) NaOH(aq) • Net ionic equation OH-(aq) + H3O+(aq) → 2 H2O(l) OH (aq) • This applies to ALL reactions This of STRONG acids and bases. STRONG Reactions of Acids & Bases: Reactions Acid-Base Neutralization Acid-Base Reactions of weak acids and strong bases: Molecular Equation: HC2H3O2(aq) + NaOH(aq) → NaC2H3O2(aq) + H2O(l) Total Ionic Equation: Total Net Ionic: Net Non-Metal Acids Nonmetal oxides can form acids in aqueous solutions: Examples: CO2(aq) + H2O(s) → H2CO3(aq) CO O(s) SO3(aq) + H2O(s) → H2SO4(aq) SO O(s) Both gases come from the burning of fossil fuels. Bases Metal oxides form bases in aqueous solution CaO(s) + H2O(l) → Ca(OH)2(aq) O(l) CaO in water. Indicator shows solution is basic. Gas-Forming Reactions Gas-Forming Gas-Forming Reactions Metal carbonate salts react with acids to the corresponding metal salt, water and carbon dioxide gas. 2HCl(aq) + CaCO3(s) → CaCl2(aq) + H2CO3(aq) decomposes decomposes Similarly: H2O(l) + CO2(g) HCl(aq) + NaHCO3(s) → NaCl(aq) + H2O(l) + CO2(g) acid base salt water Neutralization!!! Gas-Forming Reactions Group I metals: Na, K, Cs etc.. react vigorously with water 2K(s) + 2H2O(l) → 2KOH(aq) + H2(g) Metals & acid: Some metals react vigorously with acid solutions: Zn(s) + 2H+(aq) → Zn2+(aq) + H2(g) Gas-Forming Reactions CaCO3(s) + H2SO4(aq) → 2 CaSO4(s) + H2CO3(aq) CaCO (aq)...
