Question

1. Which net ionic equation best represents the reaction that occurs when an aqueous solution of barium chloride is mixed with an aqueous solution of sulfuric acid?

[A] BaCl2 + H2SO4 -> BaSO4 + 2HCL

[B] 2H+ (aq)+2Cl-(aq)-> HCl(g)

[C] Ba(2+)(aq) + SO4(2-)(aq) -> BaSO4 (s)

[D] Ba(2+)(aq)+2Cl-(aq)+2H+(aq)+SO4(2-)(aq)-> BaSO4(s)+2HCl(g)

[E] No net reaction occurs.

2. What is the net ionic equation for the acid-base reaction that occurs when acetic acid and sodium hydroxide solutions are mixed?

[A]H+(aq)+OH-(aq) -> H2O(l)

[B]H3O+(aq)+OH-(aq)->2H2O(l)

[C]HC2H3O2(aq)+NaOH(aq)->NaC2H3O2(aq)+ H2O(l)

[D]C2H3O2-(aq)   +   H+(aq)   Na+(aq)  + OH-(aq) -> Na+(aq)  +  C2H3O2-(aq)  +  H2O(l)

[E] HC2H3O2(aq) + OH- (aq) -> C2H3O2-(aq) + H2O (l)

Explanation / Answer

1)[C] Ba(2+)(aq) + SO4(2-)(aq) -> BaSO4 (s)

2)[A]H+(aq)+OH-(aq) -> H2O(l)
