96. Because atoms, molecules, and ions are very small, they are counted in units of moles, where 1 mole = 6.022 * 1023 molecules. Concentration of ions in a liquid is measured in units of moles per liter. The measure of the acidity of a liquid is called the pH of the liquid and is given by the formula

pH = - log (H),

where H is the concentration of hydrogen ions in units of moles per liter.

b. If a liquid has a pH value larger than 7.0, does one liter of that liquid contain more or fewer hydrogen ions than one liter of water? Explain.

It contains fewer hydrogen ions.

Step-by-step explanation:

For the graph in the figure below, we can notice that when (H) increases, - log (H) decreases.

So if pH > 7.0, it must indicate that there is a small number of hydrogen ions per liter. Knowing that pH of water is 7, that indicates that are fewer hydrogen ions.
