(a)

Interpretation Introduction

Interpretation:

Percent dissociation of $\text{HF}$ in $\text{0}\text{.050}\text{M HF}$ has to be calculated.

Concept Introduction:

Percent dissociation:

It is defined as concentration of dissociated acid divided by the concentration of the acid times $100\%$.

$\text{Percent}\text{dissociation =}\frac{{\left[\text{HF}\right]}_{\text{dissociated}}}{{\left[\text{HA}\right]}_{\text{initial}}}\times 100\%$
