Answer:
pH = 4.45
Explanation:
We need to find the pH of 
solution of HCl. We know that, pH of a solution is given by :
![pH=-log[H]^+](https://tex.z-dn.net/?f=pH%3D-log%5BH%5D%5E%2B)
Put all the values,
![pH=-log[3.5\times 10^{-5}]\\\\pH=4.45](https://tex.z-dn.net/?f=pH%3D-log%5B3.5%5Ctimes%2010%5E%7B-5%7D%5D%5C%5C%5C%5CpH%3D4.45)
So, the pH of the solution of HCl is 4.45.
