Question
Consider the reaction that occurs when an aqueous solution of HF is neutralized with an aqueous solution of Ba(OH)2.
-Provide the balanced molecular equation for the reaction that occurs when the solutions are mixed.
Enter your answer as a balanced chemical equation. Include phases for all species.
-Provide the complete ionic equation for the reaction.
Enter your answer as a balanced chemical equation. Include phases for all species.
-Identify the spectator ion(s) present.
-Provide the net ionic equation for this reaction.
Explanation / Answer
net equation
2HF (aq)+ Ba(OH)2 (aq) -------------> BaF2(aq)+ 2H2O (aq)
complete ionic equation
H+(aq) +2F-(aq) +Ba+2 (aq) + OH- (aq)------------> H2O (aq) + BaF2 (aq)
net ionic equaton
H+(aq) + OH- (aq)------------> H2O (aq)
F- and Ba+2 are spectator ions
