Define the molar absorptivities are 2230 for hin

Reference no: EM13492416

The acid-dissociation constant for an acid-base indicator HIn is 0.0000438. At 600 nm, the molar absorptivities are 2230 for HIn and 8900 for In-. Calculate the absorbance at 600 nm of a 1.00 x 10-4 M solution of the indicator at pH 4.81 in a 1.00-cm cell. I know what formula to use I am just having trouble finding Hln and ln.
