The answer is 264.12

The element is Bh (Bohrium). If the ion has a 1 charge, the charge can either be 1+ or 1-. So the ion has to be an element with the atomic number 107 or 109 (Bh or Mt). Using simple math, subtract the atomic number from the mass number to equal 157.

264 - 107 = 157

Sulfadiazine is a sulfa drug. The solubility of Sulfadiazine is 3.07x10-4 mol dm-3 (as acid form). The pK a of the acid form is
svetoff [14.1K]

Answer:

At pH 8.59 the precipitation of acid will form.

Explanation:

The pH below which the drug will begin to precipitate can be calculated using the relation

pH = pKa + log \frac{(S - S^{\circ})}{s^{\circ}}

where S = total saturation solubility of the drug

S° = solubility of the undissociated species

substituting the respective values in equation, we get:

pH = 6.48 + log \frac{( 4 \times 10^-2 - 3.07  \times 10^-4) }{3.07  \times 10^-7}

pH = 8.59
