Is pH depend on concentration of compound?

Answer 1

pH means -log[H], [H] is the concentration of hydrogen ion. and the concentration of hydrogen ion (also know as proton) is depend on the concentration of acid solution. the higher the proton concentration, the solution is more acidic, pH value lower. a "solid" acid will not change the colour of "dry litmus paper", because the is no water present, no hydrogen ion are present.

Answer 2

pH is an other way of expressing (low) concentration values:

It is (by definition) the negative power of 10 which equals the concentration of protons [H+] ( in mol/L) in water:

In formula:

pH = - log10[H+]Examle:

[H+] = 1.0*10-3 >> pH = 3.00

[H+] = 3.0*10-5 = 10-4.5 >> pH = 4.50

[H+] = 2.0*10-10 = 10-9.7 >> pH = 9.70

Answer 3

pH= -log10[H+], pOH = -log10[OH-] and pOH + pH = 14

So the concentation of acid (H+) and base (OH-) will affect the pH.

Strictly speaking it is activity not concentration that matters.

Answer 4

pH is a measure of the concentration of hydrogen ions in a solution and is not directly dependent on the concentration of the compound itself. However, the pH can be influenced by the concentration of acidic or basic compounds that can donate or accept hydrogen ions in the solution, altering the overall hydrogen ion concentration and thus the pH.

Answer 5

pH is a measure of the concentration of free protons in a solution (or in the case of aqueous solutions, hydronium ions).

Answer 6

Yes, concentration does affect the PH of a given substance. It is important to note that the PH depends on the concentration of the H+ ions in a solution.

Answer 7

the higher the concentration of acid or H+, the lower the pH

the higher the concentration of base or OH-, the higher the pH

Answer 8

It depends on H+ concentration pH= -log[H+]
