Answer 1

The molecular equation is:

HF(aq) + NaOH(aq) -> NaF(aq) + H2O(l)

Here HF is weak acid, it will not dissociate completely.

NaOH is strong base and will dissociate completely.

NaF is salt and string electrolyte. It will dissociate completely.

So, the complete ionic equation is:

HF(aq) + Na+(aq) + OH-(aq) -> Na+(aq) + F-(aq) + H2O(l)

Remove ions present on both sides to get net ionic equation.

The net ionic equation is:

HF(aq) + OH-(aq) -> F-(aq) + H2O(l)

Answer:

HF(aq) + OH^-(aq) -> F^-(aq) + H₂O(l)
