<u>Answer:</u> The pH of the solution is 4.51.
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.
.....(1)
Given concentration of ![[H^+]=3.1\times 10^{-5}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.1%5Ctimes%2010%5E%7B-5%7DM)
Plugging values in equation 1, we get:

Hence, the pH of the solution is 4.51.
The solution for this problem is:
Let x denote the specific rotation, R; andLet y denote the specific rotation, S = -x
Solution:60 x - 40 x/100 = - 43
20x = - 4300Divide both sides by 20The answer is:x = - 215 is the specific rotation of the pure r isomer.
