Question

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

Answer 1

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 2

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* 10^(-4)`

`pH=-\log (2.87* 10^(-4))`

`pH=3.54`

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