What is the concentration of hydrogen ions in a liter of vinegar that has a pH level of 2.5?

Explanation
We are told that the vinegar has a pH level of 2.5
To get the hydrogen ion concentration using the properties of the Algorithm
We will substitute the values of PH =2.5 into the equation so that we will have
[tex]2.5=log\frac{1}{H^{^+}}[/tex]We will make
[tex]H^+[/tex]The subject of the formula
To do so, we will find the antilog of both sides
[tex]10^{2.5}=\frac{1}{H^{^+}}[/tex]Making H the subject of the formula
Thus
[tex]\begin{gathered} H^+=\frac{1}{10^{^{2.5}}} \\ \\ H^+=10^{-2.5} \end{gathered}[/tex]Thus, the answer is
[tex]H^+=10^{-2.5}[/tex]Option B is correct
