In chemistry, yes...yes it is.
At the equivalence point, the NaF completely reacts with the HCl
The correct option that gives the equivalence point when titrating NaF solution with HCl(aq), occur at a pH value is option c);
c) <u>Below 7 because it is determined by HF (aq)</u>
Reason:
The ionic equation of the reaction taking place in the titration is presented as follows;
- Na⁺ (aq) + F⁻ (aq) + H⁺ (aq) + Cl⁻(aq) → HF (aq)+ Na⁺(aq) + Cl⁻(aq)
Therefore, by removing the spectator ions, we get;
Therefore;
The net ionic equation is the formation of hydrofluoric acid, HF, which is a
weak acid, therefore, the pH value will be <u>below 7 because it is determined </u>
<u>by HF</u>

Answer:
An Arrhenius base is a compound that increases the OH − ion concentration in aqueous solution. The reaction between an Arrhenius acid and an Arrhenius base is called neutralization and results in the formation of water and a salt.
