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

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
