While rummaging through the cabinets in your winery lab, you find a container of liquid labeled only, HCl (aq). Wondering if it will be sufficiently strong to remove the rust from your 37 Buick, you are able to reach equilibrium (at pH 7.00) through titration by adding 14.25 mL of 0.2030 M NaOH to 20 mL of this solution. What is the Molarity of the acid?
