The pH of saliva is normally in the range of 6.4 to 7.0. However, when a person is ill, the person's saliva becomes more acidic.

Firlakuza [10]

Answer: The hydrogen ion concentration of his saliva is $7.94\times 10^{-7}M$

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

To calculate the pH of the solution, we use the equation:

$pH=-\log[H^+]$

We are given:

pH of the saliva = 6.1

Putting values in above equation, we get:

$6.1=-\log[H^+]$

$[H^+]=10^{-6.1}=7.94\times 10^{-7}M$

Hence, the hydrogen ion concentration of his saliva is $7.94\times 10^{-7}M$
