    i think you find it out by titration, using an indicator and comparing the volumes of acid used to neutralize lets say 25cm3 of NaOH the one that uses less acid is H2Y so the one that uses more is HY... Im not sure though.

    cause in the 1st one where they use zinc and copper 1.1 voltage is produced, then they used tin and copper which only produced 0.5 voltage. so if you use a zinc and tin which is more reactive than copper so a charge less than 1.1 voltage will be produced. so if 0.5 is produced by tin and...

    when a carboxylic acid reacts with bases it loses the H atom from the group COOH to become COO- and H+ ions so 2 COOH groups have to be there then only 2 H+ ions will form. whatever number of atoms remain from the molecular formula after the 2 COOH are the rest of the molecule.

    because you know that tin is more reactive than copper and its cell produces a voltage of 0.5 and a zinc and copper cell produces a voltage of 1.1. so a zinc and tin will produce 1.1-0.5=0.6 voltage
