A weak acid (HA) absorbs radiation strongly in the violet region of the spectrum. The dissociation reaction for HA in aqueous solution is given by: HA+H,0 = H,0* + A where the equilibrium constant (Kg) for the dissociation reaction is equal to 3.51 x 108 At a wavelength of 427 nm, the acidic form of the weak acid has an absorptivity of 1036 and the basic form of the weak acid has an absorptivity of 650. When a sample containing a 1.50 x 103 M solution of the weak acid was analysed using a 2.00 cm sample cell, it was found to have an absorbance of 0.648. i) Identify the acidic and basic forms of the weak acid in aqueous solution, ii) determine the concentrations of the acidic and the basic forms of the weak acid present in the solution, iii) what is the ratio of the acidic to basic form of the the weak acid in aqueous solution
