A student prepared a .10M solution of acidic acid. Acidic acid has a Ka of 1.75 x 10-3. What are the hydronium ion concentration and the PH of the solution?

I think the PH is 1.76 because I hit -log(1.75 x 10-3) on my calculator and that's what I got thanks in advance for your help

  1. I got pH = 1.88, H3O+ = .0132. I see that you have H3O+ = .00132. Please explain how you got that, or is it a miscalculation?

    Acetic acid, CH3CO2H, is the active ingredient in vinegar. It's often abbreviated "HOAc". Vinegar is acidic because acetic acid makes H3O+ when it partially ionizes in water: HOAc(aq) + H2O H3O+(aq) + OAc–(aq) Suppose that
