Based on the definition of logarithms, what is the difference in hydrogen ion concentration between a substance with a pH of 2 and a substance with a pH of 3?
A substance with a pH of 2 has a 10 times higher concentration of H+  than a substance with a pH of 3.
A substance with a pH of 3 has a 10 times higher concentration of H+ than a substance with a pH of 2.
A substance with a pH of 2 has a 100 times higher concentration of H+ ions than a substance with a pH of 3.
A substance with a pH of 3 has a 100 times higher concentration of  H+ ions than a substance with a pH of 2.

The pH scale is a negative logarithmic scale, which means that it changes by factors of 10. Negative exponents are converted into fractions, so something with a pH of 1 has an H+ concentration of 10^-1. or 1/10, or 0.1. A pH of 2 represents 10^-2, 1/100, or 0.01.
Therefore, a solution with a pH of 2 is 10 times more concentrated, in terms of H+, than a solution with a pH of 3.
The first option.

The pH 2 has the hydrogen ion concentration 10 times higher than the concentration at pH 3.

pH can be defined as the negative logarithmic value of the hydrogen ion concentration in a solution.

The pH can be calculated as:

[tex]\rm pH\;=\;log\;[H^+][/tex]

The hydrogen ion concentration from the pH can be calculated as:

[tex]\rm [H^+]\;=\;10^-^p^H[/tex]

The hydrogen ion concentration at pH 2 :

[tex]\rm [H^+]\;=\;10^-^2[/tex]

Hydrogen ion concentration = 0.01 mol/L.

The hydrogen ion concentration at pH 3 :

[tex]\rm [H^+]\;=\;10^-^3[/tex]

Hydrogen ion concentration = 0.001 mol/L.

The pH 2 has the hydrogen ion concentration 10 times higher than the concentration at pH 3.
