a sample of fruit juice is found to have a hydrogen ion concentration of 2.87 x 10^-4 what would the pH be ?

The calculation of pH has a formula of pH=-lg[c(H+)]. c(H+) means the concentration of hydrogen ion in the solution. Then according to the question, we can get the pH = 3.54.

Answer: 3.54

Explanation:-

pH is the measure of acidity or alkalinity of a solution.

It is measured by taking negative logarithm of hydrogen ion concentration.

[tex]pH=-\log [H^+][/tex]

Given: [tex][H^+]=2.87\times 10^{-4}[/tex]

[tex]pH=-\log (2.87\times 10^{-4})[/tex]

[tex]pH=3.54[/tex]

As pH is 3.54 which is less than 7, the substance is acidic in nature.
