Formulate the equation for the complete combustion of benzoic acid in oxygen using only integer coefficients. [2] f (ii). The combustion reaction in (f) (ii) can also be classed as redox. Identify the atom that is oxidized and the atom that is reduced. [1] g.
Benzoic acid (/ bɛnˈzoʊ.ɪk /) is a white (or colorless) solid organic compound with the formula C6H5COOH, whose structure consists of a benzene ring (C6H6) with a carboxyl (−C (=O)OH) substituent.
Find the pH of a 0.35 M solution of benzoic acid. Find the pH of a 0.275 M hypochlorous acid solution. Ka = 3.0 x 10-8. 3) Find the pH of a solution that contains 0.0925 M nitrous acid (Ka = 4.5 x 10-4) and 0.139 M acetic acid (Ka = 1.8 x 10-5).
