Question


pls solve this

Predict the products (if any) and write the balanced chemical equation, the complete ionic equation, and the net ionoic equation Na_2SO_4(aq) + Pb(NO_3)_2(aq) rightarrow HNO_3(aq) + KOH (aq) rightarrow adding solid silver nitrate to aqucous hydrochloric acid yields... adding aqueous potasium chromate to aqueous barium chloride tyields.,.. A sample solution is given to you that may contain any or all of the following ions: Ag^2, Ba^2+, and Fe^3+. In an attempt to determine which cations(s) are present, you add the following solution solutions. You found that no precipitate formed when either an aqueous solution of NaCl or an aqueous solution of Na_2SO_4 was added to the sample solution. However, a preciptate did form when you treated the sample solution with a basic of NaOH, Which eation or cations are prersent in the sample? Give your reasoning. Balance the following redox reaction. Identify the oxidizing and reducing agents, and the subtances oxidized and reduced. C_2O_4^2-(aq) + MnO4_4^- (aq) rightarrow CO_2(g) + MnO_2 (s) in basic solution. Fe^2+ (aq) + MnO_4^-(aq) rightarrow Mn^2+ (aq) + Fe^2+ (aq) in acidic solution.

Explanation / Answer

1) Pb(NO3)2(aq) + Na2SO4(aq) -----> PbSO4(s) + 2NaNO3(aq) balanced chemical equation

Pb2+(aq) + 2(NO3)-(aq) + 2Na+(aq) + (SO4)2-(aq) ---> PbSO4(s) + 2Na+(aq) + 2(NO3)-(aq) ionic equation

Pb2+(aq) +  (SO4)2-(aq) ---> PbSO4(s)    net ionic

2) . KOH + HNO3 KNO3 solid + H2O (aq)     balanced chemical equation

K+(aq) + OH- (aq) + H+ (aq) +NO3- (aq) ----->KNO3 (aq) + H2O AQ   ionic equation

K+(aq) +NO3- (aq)----->KNO3 (aq)         net ionic

3)AgNO3(aq)+HCl(aq) ------>AgCl solid +HNO3(aq)     balanced chemical equation

Ag + (aq) + NO3- (aq) + H+(aq) + CL-(aq) --->AgCl solid + HCL (aq)   ionic equation

Ag + (aq) + CL-(aq) ------> >AgCl solid    net ionic

4) K2CrO4(aq) + BaCl2(aq)BaCrO4(s) + 2KCl(aq) balanced chemical equation

2K+(aq) + CrO4^2-(aq) + Ba^2+(aq) + 2Cl-(aq)BaCrO4(s) + 2K+(aq) + 2Cl-(aq) total ionic

Ba^2+(aq) + CrO4^2-(aq)BaCrO4(s) net ionic

3) 4H2O + 3C2O4(-2) + 2MnO4(-1) ------------- 2MnO2 + 6CO2 + 8OH(-1)   

OXIDISING AGENT = MnO4- , REDUCING AGENT = C2O4(-2)   

5Fe2+(aq) + MnO4-(aq) + 8H+(aq) ---> 5Fe3+(aq) + Mn2+(aq) + 4H2O

OXIDISING AGENT =  MnO4- ,REDUCING AGENT = Fe2+
