Unformatted text preview: PbI2(s) KNO Net ionic equation Acid­Base Reactions Acid­Base Reactions • The “driving force” is the formation The of water. of NaOH(aq) + HCl(aq) ---> NaCl(aq) + H2O(liq) • Net ionic equation OH-(aq) + H+(aq) OH (aq) ---> H2O(liq) ---> • This applies to ALL reactions This of STRONG acids and bases. STRONG Acid-Base Reactions Acid-Base CCR, page 191 Acid­Base Reactions Acid­Base Reactions • A-B reactions are sometimes called A-B NEUTRALIZATIONS because the NEUTRALIZATIONS solution is neither acidic nor basic at the end. end. • The other product of the A-B reaction is a The SALT, MX. SALT HX + MOH ---> MX + H2O OH Mn+ comes from base & Xn- comes from Gas­Forming Reactions Gas­Forming Reactions This is primarily the chemistry of metal This carbonates. carbonates CO2 and water ---> H2CO3 H2CO3(aq) + Ca2+ ---> 2 H+(aq) + CaCO3(s) (limestone) Adding acid reverses this reaction. MCO + acid ---> CO + salt Gas­Forming Gas­Forming Reactions CaCO3(s) + H2SO4(aq) ---> (aq) 2 CaSO4(s) + CaSO (s) H2CO3(aq) (aq) Carbonic acid is unstable and forms CO2 & H2O CO...
