Question
What percentage of atropine base exists as unionized (base form) in ophthalmic drops buffered at $\mathrm{pH} 6.8$, using a $\mathrm{pK}_{\mathrm{b}}$ of atropine of 4.35 at $25^{\circ} \mathrm{C}$ ?
Step 1
Step 1: Write down the equation for the dissociation of atropine base in water: \[ \text{Atropine base} \rightleftharpoons \text{Atropine} + \text{OH}^- \] Show more…
