dc.description.abstractVisible spectra of methyl red, methyl orange, p-nitrophenol, p-nitroaniline, and bromophenol  blue in calcium nitrate tetrahydrate melt have been recorded at 25°C. All the indicators react with the acidic calcium nitrate tetrahydrate melt. It is found that indicators having high pKa value in the range ≤4 can be used as  probes if  the  spectra  of acidic  and  basic forms  of such indicators in the hydrate melt are well separated. Acidity function of calcium nitrate tetrahydrate melt has been determined from the spectral data of p-nitroaniline and bromophenol blue only and its values, 1.8  and  2.6  respectively  are  estimated  from  their respective spectra.en_US
