Example 3 A sample of orange juice has a Hydrogen ion concentration of 2.9times 10^-4M . What is the pH ?

Question

Answer 1

To find the pH of the orange juice sample, we can use the formula for pH, which is:

where

is the hydrogen ion concentration in moles per liter (M).Given:

Now, plug this value into the pH formula:

Using a calculator to find the logarithm:

Using a calculator to find \(\log(2.9)\):

So,

Therefore, the pH of the orange juice sample is approximately 3.54.
