Question

What is the pH of a 3.5 x 10-5 M solution of HCl?

Answer 1

pH = 4.45

Step-by-step explanation:

We need to find the pH of
`3.5* 10^(-5)\ M` solution of HCl. We know that, pH of a solution is given by :

`pH=-log[H]^+`

Put all the values,

`pH=-log[3.5* 10^(-5)]\\\\pH=4.45`

So, the pH of the solution of HCl is 4.45.
