67. Solving a chemistry problem

14. Make a reaction equation, write down the composition of the substance at the equivalence point. Calculate the potential of the indicator electrode before the start of the titration and during the titration at the indicated moment if 0.1 N is being titrated. solution at 25 °C. Pick up the reference electrode and designate the galvanic cell. Write the equations of electrode reactions.
version number titratable solution titrant indicator electrode titration moment
14 H2S KOH Quinhydrone Titrated with 30% H2S and at 1 equivalence point
