Which of the solutions below will have the lowest ph? 0.10 m hbr 0.10 m hf 0.25 m hc2h3o2?

A.0.10 HBr

Explanation:

We are given that some solutions

We have to find the solution which have lowest pH

1.0.10 m HBr

We know that

[H+]=0.10=

We know that log 1=0 abd log 10=1

Then we get

HBr is strongest acid ,therefore, it completely ionize into its ions.

But HF and are weaker acids and do not ionize completely into its ions.

The pH of these two acids are greater than one.

Hence, the pH of HBr is lowest.

Option A is true.
