Chemistry

A mixture is prepared using 27.00 mL of a 0.0774 M weak base(pKa = 4.635), 27.00 mL of a 0.0581 M weak acid (pKa = 3.189) and1.00 mL of 0.000116 M HIn and then diluting to 100.0 mL, where HInis the protonated indicator. The absorbance measured at 550 nm in a5.000 cm cell was 0.1123. The molar absorptivity (ε) values for HInand its deprotonated form In– at 550 nm are 2.26 × 104 M–1cm–1 and1.53 × 104 M–1cm–1, respectively. 1.) What is the pH of thesolution? 2.)What are the concentrations of In– and HIn?respectively 3.)What is the pKa for HIn?
