Explain sensitivity of a spectrophotometer allows detection

Reference no: EM13705142

Problem- The sensitivity of a spectrophotometer allows detection of 1 percent of one colored form of an indicator (for example HIn) in the presence of 99 percent of the other colored form (In-). Based on this fact, over what pH range relative to its pK can an indicator be used if a spectrophotometer is employed? pH = pKIn + log [In- ]
[HIn]

I want you to clarify the chemistry in this above problem.
