The pH value is an expression of the molarity of H3O+ ions in solution. This concentration has strong impact on chemical reactions. The molarity is very small value, and therefore awkward to use. The pH scale simplifies this concentration making communication easier and faster.
Demonstrate the relationship between pH and H3O+ molarity, using the formula,
pH = -log(H3O+)
where () indicates concentration in molarity of a substance.

Typically the concentration of hydronium, H3O+, or hydroxide, OH−, ions in an aqueous solution is less than 1 M. It is not uncommon to have hydronium ion concentrations that are much smaller, such as 2.60×10−5. pH, therefore, is a convenient way to restate the hydronium concentration. pH is equal to the negative log of a hydronium ion concentration in solution: pH=−log[H3O+] Access the pH calculation simulation, which will open in a new window. Edit the concentration by typing a value...

18. Acidity of a solution is determined by the concentration Hof hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm of the concentration of hydrogen ions to define the pH scale. pH = -log H Solution A has a pH value of 5.6 and solution B has a pH value of 2.7. Compare the acidity of the two solutions. a) Solution A is more acidic by a factor of 2.07...
2 points 11 My Notes Acidity of solution is determined by the concentration C of hydrogen ions in the solution (measured in moles per liter of solution). Chemists use the negative of the logarithm the following formula. of the concentration of hydrogen ions to define the pH scale, as shown pH log (C) Lower pH values indicate a more acidic solution. (a) Normal rain has a pH value of 5.6. Rain in the eastern United States often has a pH...
