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.
What would step 1 and 2 be?
Please complete the calculations related to pH, pOH, [H3O+], and [OH-]. Remember there are special rules related to significant digits when working with pH, pOH, [H3O+], and [OH-].
