Answer: The molarity of 
in this solution is 
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
Given : pH = 10.66
Putting in the values:
![10.66=-\log[H^+]](https://tex.z-dn.net/?f=10.66%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=10^{-10.66}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-10.66%7D)
![[H^+]=2.2\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D2.2%5Ctimes%2010%5E%7B-11%7D)
Thus the molarity of in this solution is
