Question

Balance equations,find ionic equation and net ionic equationfor a double replacement reaction 1.HCl+NaCO3-->HCO3+NaCl 2.HC2H3O2+NaHCO3--->NaC2H3O2+H2CO3 Balance equations,find ionic equation and net ionic equationfor a double replacement reaction 1.HCl+NaCO3-->HCO3+NaCl 2.HC2H3O2+NaHCO3--->NaC2H3O2+H2CO3

Explanation / Answer

Weak acids and weak electrolytes do notdissociate to their components in the ionic and net ionicequations. Cross out whatever species that occur in both the reactants' andproducts' side. 1) HCl (aq) + NaCO3 (aq) ---> HCO3 (aq) +NaCl (aq) Ionic: H+ (aq) + Cl- (aq) +Na+ (aq) + CO3-(aq) ---> HCO3- (aq) +Na+ (aq) + Cl-(aq) Net Ionic: H+ (aq) + CO3-(aq) ---> HCO3- (aq) 2) HC2H3O2 (aq) +NaHCO3 (s) --->NaC2H3O2 (aq) +H2CO3 (aq) Ionic: HC2H3O2 (aq) +Na+ (aq) + HCO3-(aq) ---> Na+ (aq) +C2H3O2- (aq) +H2CO3 (aq) Net Ionic:HC2H3O2 (aq) +HCO3- (aq) --->C2H3O2- (aq) +H2CO3 (aq)
