What is the pH of a solution made by dissolving 0.1 moles of NaOH and 0.2 moles of HCl in 2 L of water?

pH = 1.30

Explanation:

The reaction that would take place between HCl and NaOH is:

In this problem, the 0.1 moles of NaOH would react with 0.1 moles of HCl, leaving 0.1 moles of HCl unreacted.

These 0.1 HCl moles are dissolved in 2 liters, thus the concentration of H⁺ species is:

Finally we calculate the pH:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
