Yes, that is correct. Atropine sulfate, like many weak bases, exhibits greater solubility at higher pH levels. This is because as pH increases, the concentration of hydroxide ions (OH-) also increases. The presence of these hydroxide ions helps in the ionization of atropine sulfate, resulting in the formation of more soluble ions. Therefore, at higher pH levels, a larger proportion of atropine sulfate molecules exist in their ionized form, leading to an increase in solubility.
