1. A student prepared a base solution using 7 mL of 6M NaOH diluted with distilled water to a final volume of approximately 400 mL. The student titrated a standardized solution of hcl to determine the exact concentration of the prepared base solution. She found that it took 24.55 mL of the base solution to neutralize 20.00 mL of a 0.99897 M HCl solution. What is the molarity of the prepared naoh solution as determined in the titration? How many moles of OH are present when the end point is reached? What color should the solution appear at end point?
