It contributes PO4-3, OH-, HPO4-2, and H2PO4- to the net ionic equations. a) the balanced molecular equation and A) atoms b) lithium NaCl(s) d) There is no reaction; all possible products are soluble The NaOH concentration is normally 3 to 6 M, and the solution must be analyzed periodically. a) Both barium nitrate and sodium chloride precipitate Pb2+ (aq) + 2NO3- (aq) + 2 K+ (aq) --> PbI2 (s) + 2K+ (aq) + 2 NO3- (aq), Ions that appear on both sides of a complete ionic equation; they remain unchanged by the reaction, Once the spectator ions are canceled out from the complete ionic equation, we are left with a net ionic equation Molecular compounds that are acids or bases -Acids (Bronstred-Lowry): Donate H+ -Bases: accept H+ //Ex: HCl (acid) +NH3 (base) -->Cl- + NH4+ What are the strong acids? A) Zn (s) + 2Br- (aq) ZnBr2 (aq) M = 0.220 mol NH3/120.0 L c) iron AgNO3 (aq) + NaCl (aq) ---> AgCl (s) + NaNO3 (aq), Ag+ (aq) + NO3- (aq) + Na+ (aq) + Cl-(aq) --> AgCl(s) + Na+ (aq) + NO3- (aq) NaCl will conduct electricity, but not Methanol, the clustering of solvent molecules around a solute particle which helps to stabilize the ions in solution; Prevents cations and anions from recombining, What dissolved species are present in a solution of, A substance (Strong acids, strong bases and most salts) that is completely ionized in solution, A substance that only partially ionizes It undergoes a disproportionation reaction to Na- and Na+, oxidation is the appropriate stoichiometric factor the.
