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.

KOH is a base therefore its pH will be above seven. According to table M when tested with the indicator bromcreeol green The solution will turn blue.

In which solution will the green bromocresol appear blue?

In aqueous solution, raw bromocresol will be ionized to give a monoanionic (yellow) form, which also decomposes at a higher pH to give a dianionic (blue) form, which is significantly enhanced: Acid dissociation constant (pKa) of this reaction -4.8.

What is the pH of raw bromocresol that changes color?

The Bromo Cresol Green Indicator has a wide range of functionality so follow the appropriate guidelines as per the protocol for each application. Green solution. Wipe without particles. At pH 3.8, the indicator turns yellow and at pH 5.4, the indicator is blue-green.
