A potentiometer wire is 100 cm long and a constant potential difference is maintained across it. Two cells are connected in series first to support one another and then in opposite direction. The balance points are obtained at 50 cm and 10 cm from the positive end of the wire in the two cases. The ratio of emf's is :

An electrolytic cell contains a solution of Ag_(2)SO_(4) and platinum electrodes. Current is passed until 1.6 g. of O_(2) has been liberated at anode. The amonut of Ag deposited at cathode would be

An electric bettle has two coils. When one coil is switched on it takes 15 minutes and the other takes 30 minutes to boil certain mass of water. The ratio of times taken by them, when connected in series and in parallel to boil the same mass of water is :

Three electrolytic cells A,B,C containing solutions of ZnSO_(4) , AgNO_(3) and CuSO_(4) , respectively are connected in series. A steady current of 1.5 amperes was passed through them until 1.45 g of silver deposited at the cathode of cell B. How long did the current flow? What mass of copper and zinc were deposited?

Electrolysis involves electronation and de-electronation at the respective electodes. Anode electrolytic cell is the electode at which de-electronation takes place whereas at cathod electronation is noticed. If two or more ions of same charge are to be electonated or deelectronate the ion having lasser discharge potential is discharged. Discharge potential of anion refers for EP_(OP)^(@) of E_("RP")^(@) as the case may be. The products formed at either electode is given in terms Faraday's laws of electrolusis i.e. w=(Eit)/(96500) During electrolysis of CuSO_(4(aq)) , the pH of solution becomes

When two cells of different emf.s are connected in series to an external resistance the current is 5A. When the poles of one cell are interchanged, the current is 3A. The ratio of emf.s of two cell is

Three equal resistance each of 3Omega are in series and connected to cell of internal resistance one ohm. If three resistances are parallel and connected to the same cell. Then the ratio of the respective currents through the electric circuits in the two cases is

Electrolysis is the process in which electrical energy is converted to chemical energy. In electrolyte cell, oxidation takes place at anode and reduction at cathode. Electrode process depends on the electrode taken for electrolysis. Amount of substance liberated at an electrode is directly proportionation to the amount of charge passed through it. The mass of substance liberated at electrode is calculate using the following realation : m=(itE)/(96500) Here, E represent the equivalent mass and 96500 C is called the faraday constant. Faraday (96500 C) is the charge of 1 mole electron i.e., 6.023 xx 10^(23) electrons, it is used to liberate on gram equivalent of the substance. The platinum electrodes were immersed in a solution of cupric sulphate (CuSO_4) and electric current is passed through the solution. After sometimes, it was observed that the colour of copper sulphate disappeared with evolution of a gas at the electrode. The colourless solution contains.
