When an electric current is passed through water during the process of electrolysis?

When an electric current is passed through water during the process of electrolysis two gases are formed one gas has a boiling point of 183 C and the other has a boiling point of 253 C is this event a physical change or a chemical change?

In thic electrolysis reaction two gases are formed, one is oxygen with boiling point of -183°C and second one is hydrogen with boiling point of -253°C. This is chemical change because from one molecule two molecules are produced and because they have new boiling points, boiling point of water is 100°C.

What happens when an electric current is passed through water?

When electric current is passed through water, water dissociates into hydrogen and oxygen. Hydrogen is deposited over negative pole and oxygen is deposited over positive pole. Deposition of hydrogen and oxygen at different poles is visible in the form of bubbles.

When an electric current is passed through acidulated water?

When an electric current is passed through acidified water, 112ml of H2 gas at NTP is collected at the cathode is 965 seconds.

When an electric current is passed through a conducting solution?

The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes of colour of solutions may occur.

What has occurred when metal changes color because of tarnishing?

Answer is: A chemical change occured when a metal changed color because it reacted with another substance. In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.

Can we pass electricity through water?

Electricity flows through water because it contains ions of dissolved salts and metals. Distilled water, which does not contain impurities, does not conduct electricity.

Does electricity pass distilled water?

Answer: The availability of ions is very important to conduct electricity. Distilled water is a pure type of water which does not contain any ions in it. Thus rainwater is conducting electricity while distilled water is not conducting electricity.

What happens when electric current passes through water by keeping two electrodes immersed in it?

Answer: When electrodes are immersed in water and current was passed through water; bubbles of oxygen and hydrogen are produced. Oxygen bubbles are formed at the electrode connected to the positive terminal. Hydrogen bubbles are formed at the electrode connected to the negative terminal.

When an electric current is passed through any wire?

When an electric current is passed through any wire a magnetic field is produced around it. When an electric current is passed through any wire, a magnetic field is produced around it.

What happens when an electric current is passed through the copper sulphate solution?

When electric current is passed through the copper sulphate solution, copper sulphate dissociates into copper and sulphate. The free copper gets drawn to the electrode connected to the negative terminal of the battery and gets deposited on it.

When an electric current is passed through an electrolyte takes place?

When an electric current is passed through a cell having an electrolyte, the positive ions move towards the cathode and the negative ions towards the anode. If the cathode is pulled out of the solution, the circuit will not be complete and the ions will have no direction and thus they will move randomly.

What type of chemical reaction is takes place when electricity is passed through water?

When electricity is passed through water, hydrogen and oxygen are given out – Decomposition Reaction.

What do you observe on passing electric current?

When an electric current flows through a conducting solution, it causes a chemical reaction or chemical change. The chemical reaction brought about by an electric current may produce the following effects: 1)Bubbles of a gas may be formed on electrodes. 3)Changes in colour of solution may occur.

Which one of the following solution will not conduct electricity?

Vegetable oil won’t conduct electricity under normal potential difference, all other options will conduct as they can give ions for conduction.
