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

Verified Answer :

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.

\(pH=-\log [H^+]\)

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

\(pH=-\log (2.87\times 10^{-4})\)

\(pH=3.54\)

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