If the pH of tomato juice is 4.1 then what hydrogen ion concentration?

To determine the hydrogen ion concentration [H+] of tomato juice with a pH of 4.1, we can use the following formula:

pH = -log[H+]

Rearranging the formula to solve for [H+]:

[H+] = 10^(-pH)

Plugging in the given pH value:

[H+] = 10^(-4.1)

[H+] ≈ 7.94 × 10^(-5) moles per liter (M)

Therefore, the hydrogen ion concentration in tomato juice with a pH of 4.1 is approximately 7.94 × 10^(-5) M.
