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. (a) When Marco is sick, he tests the pH of his saliva and finds that it is 6.1. What is the hydrogen ion concentration of his saliva

The hydrogen ion concentration of his saliva is

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:

We are given:

pH of the saliva = 6.1

Putting values in above equation, we get:

Hence, the hydrogen ion concentration of his saliva is

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
