Question

The pH of a solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The

pH of a solution is given by pH = -log x where x represents the concentration of the hydrogen ions in the solution
in moles per liter. Find the hydrogen ion concentration if the pH = 4.4.

Answer 1

The hydrogen ion concentration for a solution with a pH of 4.4 is calculated using the inverse of the logarithm, resulting in a concentration of 3.98 × 10^-5 moles per liter.

Step-by-step explanation:

The student has asked to find the hydrogen ion concentration when the pH is 4.4. The pH is described as the negative logarithm of the hydrogen ion concentration in a solution, represented by the equation pH = -log[H+]. By using the inverse mathematical operation of taking the antilog, we can calculate the hydrogen ion concentration.

To find the hydrogen ion concentration (x), we use the equation:

x = 10-pH

For pH = 4.4:

x = 10-4.4

Thus:

x = 10-4.4 = 3.98 × 10-5 moles per liter

This is the concentration of the hydrogen ions in a solution with a pH of 4.4.
