What concentration of H+ ions does a substance with a pH of 3 have​

Answer: 1 x 10-3 mol/L Explanation: Question What concentration of H+ ions does a substance with a pH of 3 have​ the pH is the negative log of the H ion concentration in moles/liter so pH3 has a hydrogen ion concentration of 1 x 10-3 mol/L

Final answer: The pH scale measures the concentration of H+ ions in a solution. A substance with a pH of 3 has an H+ ion concentration of 1 x 10^-3 M. Explanation: The pH scale is a logarithmic measurement of the concentration of hydrogen ions (H+) in a solution. The pH of a solution is defined as the negative logarithm (base 10) of the concentration of H+ ions. So, a substance with a pH of 3 will have a hydrogen-ion concentration of 10^-3 moles per liter. Therefore, the H+ ion concentration for a substance with a pH of 3 is 0.001M, or 1 × 10^-3 M. Learn more about pH and H+ ion concentration here: brainly.com/question/32211540 #SPJ3
