If a setup is prepared in which a container filled with water and few drops of dilute sulphuric acid to it with graphite cathode and anode,then on passing the current , the hydrolysis of water takes place... if we cover the electrodes with test tubes the hydrogen and oxygen gas are collected in test tubes at different electrodes.i have 2 questions...

1.which gas will be collected at which electrode?

2.why the amount of gas collected in one test tube is double of the amount collected in another test tube.
