6-7: Ionization Constants of Weak AcidsAn acid-base indicator is usually a weak acid with a characteristic color in the protonated (acid) anddeprotonated (conjugate base) forms. In this assignment, you will monitor the color of an acetic acidsolution containingBromocresol Greenas an indicator, as the pH is changed and then you will use yourdata to calculate the ionization constant,Ka, for the bromocresol green indicator and compare to anaccepted value.1.StartVirtual ChemLab,selectAcid-Base Chemistry,and then selectIonization Constants of WeakAcidsfrom the list of assignments. The lab will open in the Titrations laboratory. Bottles of 0.1104 MNaOH and 0.1031 M HAc (acetic acid) will be on the lab bench. The buret will be filled with theNaOH solution and a beaker containing 10.00 mL of the HAc solution will be on the stir plate. Thestir plate will be on, a small amount ofBromocresol Greenindicator has been added to the beaker,
