Ethanol physical constants
WebApr 13, 2024 · This work aimed to the study effect of ethanol ratios on the acidity constants of bromocresol purple. The acidity constants of BCP were determined in binary mixtures of water with ethanol containing 0, 30, 40, 50, 60, and 70% (v/v) using spectrophotometric methods. The results indicate the dependence of acidity constants on the ratio of … WebPhysical Form: A notation of the physical phase, color, crystal type, or other features of the compound at ambient temperature. Abbreviations are given below. mp: Normal melting point in °C. A value is sometimes followed by “dec”, indicating decomposition is observed at the stated temperature (so that it is probably not a true melting point).
