O7) Choose the FOUR FALSE statements from the following (4 points) (If you choose more than four you lose points) a) For methyl red experiment, two wavelengths were used based on the highest molar absorptivity of the acidic and basic forms. b) The number of moles of oxalic acid (solubility as a function of temperature experiment) is determined by titration; moles of oxalic acid = moles of NaOH. c) The value of rate constant and order of reaction changes with changing the temperature. d) The surface tension is used to determine the area of one molecule. e) The solubility of oxalic acid at 20C is higher than that at 5C. f) The binodal curve separated the one-phase from the two-phase mixtures. g) In the adsorption experiment, the indicator used for titration is phenolphthalein. h) In the solubility as a function of temperature experiment, ethanol is used as the solvent for oxalic acid. i) In the adsorption experiment, we study the adsorption of charcoal on glass. j) The salt used in the salt effect experiment is KCl
