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 [+] is the hydrogen ion concentration. a. If the hydrogen ion concentration in a solution is 4.92 × 10-³ mol/L, the pH is b. If the pH of a solution is 3.078, the hydrogen ion concentration is mol/L.
For BrO−, enter an equation that shows how the anion acts as a base. Express your answer as a chemical equation including phases.
Household vinegar is a dilute solution of acetic acid. A sample of household vinegar was measured to have a hydronium ion concentration of 5.8 x 10-3 mol/L. Determine the pH of the sample. Do not show your work. Record only your final answer with the correct number of significant digits. Remember, pH does not have units! Hand soap is effective at preventing bacterial contamination. Calculate the hydronium ion concentration in a brand of hand soap with a pH of 10.5 You MUST show your work. Record your answer in scientific notation with the proper significant digits and units.
