You are about to begin a titration of an unknown acid of which you have very little sample. YOu added 10.00ml volumetrically to a 125 ml erlenmeyer flask containing 50.0 ml of distilled water, but before you started the titration you realized that you do not have any indicator. Not wanting to waste the expensive sample, you decided to measure the pH of the solution and determined it to be 1.85. What was the concentration of the orginal acid sample? (Hint: it is a monoprotic acid)
