4.3

Explanation:

Data provided in the question as per the question is as follows

k_b = 1.6 \times 10^{-6}

Now we use the log in both the sides

So,

Pk_b = -log\ k_b = -log (1.6 \times 10^{-6})

Pk_b = 5.795

And, C = 0.0015

log c = -2.823

Now pH is

= \frac{1}{2} (Pk_b - log\ c)

= \frac{1}{2} (5.795 - (-2.823))

= 4.3

Hence, the pH of the solution of 0.0015 M morphine is 4.3 and the same is to be considered by applying the above formulas and the calculations part
