Water in contact with air is acidic, rather than neutral,
dueto dissovled carbon dioxide. water in equilibrium with theair
contains 4.4 x 10 -5% co2. theresulting
carbonic acid, h2 co3 , gives thesolution a
hydrogen ion concentration of 2.0 x10-6m , about 20
times larger than thatof pure water. calculate the ph of the
solution.

5.7

Explanation:

The pH can be calculated by:

pH = -log[H⁺]

Where [H⁺] is the concentration of hydrogen ions. The pH is a way to identify if the  solution is an acid or a base. When pH is equal to 7, the solution is neutral, when it is less than 7, it is acid, and when it is larger than 7, it's a base.

So, for the acid solution given, [H⁺] = 2.0x10⁻⁶ M

pH = -log(2.0x10⁻⁶)

pH = 5.7

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?
