C. Acids, Bases, Salts. Acids – ionize to form H + sour taste proton donors increase concentration of H +. C. Acids, Bases, Salts. Acids – ionize to form H + a. monoprotic HCl, HNO 3 b. polyprotic H 2 SO 4 , H 2 CO 3 , H 3 PO 4 H 2 SO 4(aq) H + (aq) + HSO 4 - (aq)
E N D
C. Acids, Bases, Salts • Acids – ionize to form H+ • sour taste • proton donors • increase concentration of H+
C. Acids, Bases, Salts • Acids – ionize to form H+ • a. monoprotic • HCl, HNO3 • b. polyprotic • H2SO4, H2CO3, H3PO4 H2SO4(aq) H+(aq) + HSO4-(aq) HSO4-(aq) H+(aq) + SO4-2(aq) strong weak
2. Bases – ionize to form OH- • bitter taste • react with proton donors • increase concentration of OH- • ionic hydroxides • KOH, NaOH, Ca(OH)2 ex. Ca(OH)2(aq) Ca+2(aq) + 2 OH-(aq) strong
2. Bases – ionize to form OH- b. others (ammonia) • NH3 ex. NH3(aq) + H2O(l) NH4+(aq) + OH-(aq) weak
Strength of Acids/Bases 3. Strong vs Weak Acid/Base completely partially ionize ionize
Common Strong Bases • All Group I & II A Metal Hydroxides
D. Solution Reactions • 1. Neutralizations acidbasewatersalt HCl(aq) + NaOH(aq) H2O(l) + NaCl(aq) 2 HBr(aq) + Ba(OH)2(aq) H2O(l) + BaBr2(aq)
