Literature value of benzoic acid

Web14 aug. 2024 · The larger the Ka, the stronger the acid and the higher the H + concentration at equilibrium. Like all equilibrium constants, acid–base ionization constants are actually measured in terms of the activities of H + or OH −, thus making them unitless. The values of Ka for a number of common acids are given in Table 16.4.1. Web• Determine the mixed melting point of a 1:1 mixture of benzoic acid and 2-naphthol. • Determine the identity of an unknown based on melting point data. First, determine the melting point of both benzoic acid (mp 122 °C) and 2-naphthol (mp 123 °C). Determine how close your measured values come to the literature values. Record your results
