Mixing Acids and Bases

Writing neutralization equations When acids and bases are mixed, a salt forms NaOH + HCl  H2O + NaCl base + acid  water + salt Ca(OH)2 + H2SO4  2H2O + CaSO4 Question: Write the chemical reaction when lithium hydroxide is mixed with carbonic acid. Step 1: write out the reactants LiOH(aq) + H2CO3(aq)  Step 2: determine products … H2O and Li1(CO3)2 LiOH(aq) + H2CO3(aq)  Li2CO3(aq) + H2O(l) Step 3: balance the equation 2LiOH (aq) + H2CO3 (aq)  Li2CO3 (aq) + 2H2O (l) lithium hydroxide + carbonic acid  lithium carbonate + water

Assignment Write balanced chemical equations for these neutralization reactions. Under each compound give the correct (IUPAC) name. iron(II) hydroxide + phosphoric acid Ba(OH)2(aq) + HCl(aq) calcium hydroxide + nitric acid Al(OH)3(aq) + H2SO4(aq) ammonium hydroxide + hydrosulfuric acid KOH(aq) + HClO2(aq)

a) 3Fe(OH)2(aq) + 2H3PO4(aq)  Fe3(PO4)2(aq) + 6H2O(l) iron(II) hydroxide + phosphoric acid  iron (II) phosphate b) Ba(OH)2(aq) + 2HCl(aq)  BaCl2 (aq) + 2H2O(l) barium hydroxide + hydrochloric acid  barium chloride c) Ca(OH)2(aq) + 2HNO3(aq)  Ca(NO3)2(aq) + 2H2O(l) calcium hydroxide + nitric acid  calcium nitrate d) 2Al(OH)3(aq) + 3H2SO4(aq)  Al2(SO4)3(aq) + 6H2O(l) aluminum hydroxide + sulfuric acid  aluminum sulfate e) 2NH4OH(aq) + H2S(aq)  (NH4)2S(aq) + 2H2O(l) ammonium hydroxide+ hydrosulfuric acid ammonium sulfide f) KOH(aq) + HClO2(aq)  KClO2(aq) + H2O(l) potassium hydroxide + chlorous acid  potassium chlorite
