The number of hydrogen ions would equal the number of hydroxide ions in a solution with a ph of

The correct answer for the blank is-

pH of 7.

There can be primarily three types of aqueous solution depending upon the pH value ( which represents the acidity or basicity of the solution). A pH scale ranges from 1 to 14.

The pH value 7 relates to neutral solution, above 7 is for basic solutions  and below 7 shows solution is acidic.

Neutral solution means the hydrogen ion concentration is equal to the concentration of hydroxide ions.

Example of neutral solution- Water

trachea, alveoli, lung capillaries, arteries

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
