Answer 1

Answer #1

Answer

We know that

pH= -log[H+] or [H+]= 10^-pH

here pH= 3 and [H+]= hydrogen ion concentration =?

[H+]= 10^-3 = 1*10^-3 mol/L (option A)

pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H+], of a solution:

pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H+], of a solution: pH = -log[H+]Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, [OH-], are related to each other by the Kw of water: Kw = [H+][OH-] = 1.00 x 10-14where 1.00 x 10-14 is the value at approximately 297 K. Based on this relation, the pH and pOH are also related to each other as 14.00 = pH...

The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in terms of base 10 logarithms. pH = -log(H+) where (H+) is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 9.82 x 10 mol/L, the pH is b. If the pH of a solution is 3.510, the hydrogen ion concentration is mol/L.
