to make it dissociate as pure water doesnt conduct electricity so impurities are added. you cana also add salt.

i) Hydrogen gas will be formed at the cathode while oxygen gas will be formed at the anode.
ii) A water molecule consists of two atoms of hydrogen and one atom of oxygen. So when water dissociates, one electrode has double volume of gas as compared to the other electrode.
iii) Adding an acid makes the water conduct electricity. Distilled water is a non conductor of electricity. To make the water conduct electricity for electrolysis to occur, dilute H2SO4 is added.

I) Hydrogen will collected at cathod and oxygen at anod. ii) Volume of hydrogen gas will double to the proportion of the oxygen so when the will decompose the ratio will be 2:1. iii) H2so4 is used because it is a dehydarting agent so it will act as a catylist and dissosiate the water molecule speedly.

(i) At cathode – Hydrogen gas (H2)
At Anode – Oxygen gas (O2)
(ii) Hydrogen gas is double of that of oxygen gas because 2 molecules of
Hydrogen are liberated.
While only 1 molecule of oxygen is liberated.
(iii) water is not a good conductor of electricity or we can say that it is not that efficient in the flow of electric current through it. Hence to improve the flow of electric current through it we add H2SO4(acid) to improve its conductivity.

hydrogen at cathode and oxygen at anode
• -4
a) At cathode = Hydrogen ( H2)
At anode    = Oxygen (O2)
This is because hydrogen is a cation whereas oxygen is an anion.
During electrolysis cation goes to cathode whereas anion goes to anode.

b) H2O dissociates to form 2 molecules of hydrogen and 1 molecule of oxygen.Hence volume of  volume of gas collected in one electrode is double of the other.

c) Pure water is a bad conductor of electricity. H2SO4 is a good electrolyte or conductor since it dissociates to for ions almost completely.Hence H2SO4 is added to water.

(i) At cathode, Hydrogen gas (H2) gas is collected while at anode Oxygen gas (O2) gas is collected.

(ii) It is because Water(H2O) is made when hydrogen and oxygen combine in the ratio 2:1 by volume, the gas with double volume is hydrogen. Thus, on decomposition of water, the volume of hydrogen is twice than that of oxygen gas.

(iii) Water by itself is not a good conductor of electricity. While acids are good conductors of electricity. So, a few drops of dilute sulphuric acid (H2SO4) is added to water to make it a good conductor of electricity and allow current to flow through it easily.

1) The gas collected at the cathode is hydrogen and the gas collected at anode is Oxygen gas..

2) The volume of gas ( hydrogen ) collected in one electrode is double of other gas ( Oxygen ) because in water ( H2O ) ,there is two atoms of hydrogen gas..

3) A few drop of dilute H2SO4 is added to water to make the water able to conduct electricity .Since Pure water can not be electrolysed easily.

2.hydrogen contains two ions as oxygen not.

(i). In anode the hydrogen gas is collected because hydrogen is a electropositive element.
Where as in cathode oxygen will be collected because oxygen is electronegative element.

(ii). The gas collected in one test tube is double of another one because the in the water the presence of hydrogen and oxygen is in the ratio of 2 : 1
Therefore the volume of hydrogen is double the volume of oxygen.

(iii). Pure water does not contain electricity or say it does not let the electricity to pass through it and if electricity will not pass then electrolysis wouldn't be possible. So, when H2SO4 is added to water the water gains the free ions of hydrogen and as hydrogen ion are capable of containing electricity then the electrolysis takes place. So few drops of H2SO4 is added.

1. hydrogen at cathode and oxygen at anode 2. The volume of hydrogen (cathode) is double than oxygen (anode) because during electrolysis water is break down in the ratio of 2:1(H,O) 3. In pure water electricity is not pass so we need a acidic medium like H2SO4 for electrolysis

In electrolysis of water hydrogen is collected at cathode and oxygen is collected at anode. The volume of gas collected at cathode is more because the ratio of hydrogen to water is 2:1. Electrolysis of pure water is very low because water is a covalent compound. To
increase the conductivity of water, a few drops of dilute H2SO4 is added

1)Gas collected at anode is Hydrogen and gas collected at anode is oxygen.
2)In a molecule of water the hydrogen atoms are double than that of oxygen. Therefore the volume of gas collected at one rod is double than that of other.
3)As we know the movement of ions is necessary for conducting electricity.Thus to make possible movement of ions in water some drops of H2SO4 are added to Water.

I Hope it helps you !!!!

1.At cathode hydrogen gas and at anode oxygen gas.
2.Because in the water molecule there are two atoms of hydrogen gas and one atom of oxygen gas present.
3.This is because the dilution of acid is a highly exothermic reaction, so always add acid to water drop -by -drop not water to acid.

In the electrolysis of water, hydrogen gas is evolved at the cathode and oxygen gas is evolved at the anode. Hydrogen produced is double the oxygen because in H2O(water), there are two hydrogen atoms for each oxygen atom. A few drops of dilute sulphuric acid (H2SO4) are added to water to increase its conductivity as pure water is a poor conductor of electricity.

At cathode - hydrogen gas
At anode- oxygen gas
2 molecules of hydrogen combine with 1 molecule of oxygen to form h2o so the volume of h2 is double than o2
When a burning splinter is brought near the gas the burning splinter extinguishes near the h2 gas while the burning splinter keep burning more near the o2 gas

As we all know that cathode is negatively charged electrode and anode is positively charged elctrode. When electrolysis of water take place then it break into hydrogen which is positively charged gas and oxygen which is negatively charged as a result hydrogen gas collected on cathode and oxygen gets collect on anode. Volume of hydrogen gas is doubled because during chemical reaction we take elements in form of 2:1 in which atom of hydrogen is double. For not affecting the quality of water we add only few drops of hydrogensulphate...hope u like this ans..and able understand it easily...thank u

1. In the electrolysis of water the gas collected at cathode is hydrogen and the gas collected at anode is oxygen.2
2. Water composition is 2atoms of H and 1atom of O . Therefore H is double than O . The two electrodes collect H and O separately . We know that hydrogen composition in water is double than oxygen , so we find volume of gas collected in one electrode is double than volume of gas collected in another electrode .
3.To increase the conductivity of water a few drops of sulphuric acid is added . Being a strong acid it can ionize completely to release H+ ions. These H+ ions are responsible for the conduction of electricity. To carry out electrolysis in water,a few drops of sulphuric acid is added to the water.
