Which of the following is the net ionic equation for the reaction between aqueous sodium fluoride and hydrochloric acid?

Question

a. NaF(aq)+HCl(aq)→NaCl(aq)+HF(aq)

b. Na+(aq)+F−(aq)+H+(aq)+Cl−(aq)→Na+(aq)+Cl−(aq)+HF(aq)

c. Na+(aq)+Cl−(aq)→NaCl(aq)

d. F- (aq)+H+(aq)→HF(aq)

Answer 1

The molecular equation for this reaction is:

NaF(aq) + HCl(aq) ==> NaCl(aq) + HF(aq)

Since HF is a weak acid, we will not ionize it and will write the net ionic equation as follow:

H+(aq) + F-(aq) ==> HF(aq) ... answer (d)
