Asked by Ericka
The approximate concentration of a hydrochloric acid solution is 0.5M. The exact concentration of this solution is to be determined by the titration with 0.5M solution of sodium hydroxide.
A 10.00 ml of HCl solution was transferred by pipet to an Erlenmeyer flask. What is the approximate hydronium ion concentration and pH of the solution in the flask before the titration begins.
Im not quite sure how to do this, or if there's a formula I can use to solve it.

The approximate concentration of the HCl solution that you have on hand is 0.5M. Therefore, if you transfer 10.00 mL of that HCl solution to an Erlenmeyer flask, the concentration of the HCl still is approximately 0.5M. Since HCl is a strong acid and ionizes 100%, the hydronium ion concentration is approximately 0.5M and pH = -log(H3O^+).
