Chapter 9: November 5, 2015    Aqueous Reactions  1. Some ionic compounds and molecular acids dissociate and ionize respectively in H2​ to  form ions  a. ionic compounds: solubility rules (see slide 9 from presentation)  b. molecular acids: acid strength → strong acids  2. Precipitation Reactions: occurs when you take two solutions, mix them, and a solid is  created; this solid is known as tprecipitate  a. this solid must be insoluble in2​​ i. to determine this, go back to the solubility rules!  3. Ex: KI (aq) + Pb(NO​3​2 ​) ​   To see if this reaction is possible and determine products:  a. Are the reactants soluble in 2​ ​Check the solubility rules, KI­yes, lead  nitrate­yes  b. If yes, dissociate them into ions.   i. make sure to check the charges! K​+  + Pb​+ NO​ 1 3​ c. Determine the possible products by combining the cation from one reactant and  the anion from the other reactant​NO​  + PbI​ 3​ 2  i. Make sure that this is reduced to the lowest whole number  d. Ask yourself, is the product soluble or insoluble in water?   i. If soluble, it is aqueous and they are ions in the solu​NO​.3​q)  ii. If insoluble, they will be solids and they will crash out of the solution  (precipitate!)PbI2​(s)  e. Balance your equation. 2KI (aq) + Pb(NO​ ) (aq) → 2KNO​  (aq) + PbI (s)  3​2​ 3​ 2 ​ 4. So what physically just happened in the example 3?   +​ ­ a. Spectator ions: K​  and NO​ 3​ i. are ions in solutions that are unchanged in the reaction  ii. ions as reactants and ions as products  iii. hence “spectators” ;­)     No Reaction  1. KI (aq) + NaCl (aq) →   a. KI­soluble in water → K​ +   ​ b. NaCl­soluble in water → Na​ + Cl​  c. KCl + NaI   d. KI (aq) + NaCl (aq) → KCl (aq) + NaI (aq)  i. no precipitates  ii. this actually means that there is no reaction since there are no new  precipitates    Aqueous Reactions  1. Molecular equation: a balanced equation that shows the complete neutral formulas for  each compound, even if they are ions in the solution  a. 2KI (aq) + Pb(NO​ 3​2​aq) → 2KNO​ 3​(aq) + PbI2 ​s)  b. No reaction: KI (aq) + NaCl (aq) → no reaction  2. Complete Ionic equations: a balanced chemical equation that shows all the species as  they actually are in the solution  a. all soluble compounds → written as ions → (aq)  b. all insoluble compounds → written as a molecular formula → (s)  3. Net ionic equation: a balanced equation that shows only the species that actually  changed during the reaction  a. remove spectator ions from the complete ionic equation    Acids and Bases  +​ 1. Arrhenius acid: substances that produces protons (H​ ) when dissolved in water  a. ex: HCl (aq) → H​ + (aq) + Cl (aq)  b. HCl (aq) + H​ 2​(l) → H​3​ (aq) + Cl (aq)  i. H​ O is a hydronium ion (which is essentially the proton)  3​ ii. chemists use the hydronium ion and proton interchangeably in H​ 2​ and  therefore write the initial example a  2. Arrhenius base: substance that produces hydroxide (OH​ ­) when dissolved in water  a. typically always a metal and a hydroxide ion  b. ex: NaOH → Na​ + + OH​­  c. NH​ 3​is also a base in a solution of water  i. NH​ 3​ H​2​→ NH​ 4​ + OH​­  3. Polyprotic acids: are acids with more than one ionizable proton, which are released  sequentially  +​ 2­ a. ex: H​2​O​4​→ 2H​  + SO​4​ i. treat the acids like ionic compounds and dissociate them!  ii. the two protons that are released makes it polyprotic  b. HC​ H​O​ IS AN EXCEPTION TO THE POLYPROTIC ACIDS  2​ 3​ 2 ​ i. this is because only one of the hydrogens can be removed  4. Polyvalent base: are bases with more than one hydroxide  2+​ ­ ​ a. ex: Ca(OH)​ 2​aq) → Ca​  (aq) + 2OH​(aq)
