In a laboratory investigation, an HCl (aq) solution with a pH value of 2 is used to determine the molarity of a KOH (aq) solution. A 7.5-milliliter sample of the KOH (aq) is exactly neutralized by 15.0 milliliters of the 0.010 M HCl (aq). During this laboratory activity, appropriate safety equipment is used and safety procedures are followed. State the color of the indicator bromocresol green if it is added to a sample of the KOH (aq) solution.
