A group of students carried out electrolysis of acidified water in the laboratory. By the end of the experiment two gases were collected in the test tubes at both the electrodes.
Name the gases collected at cathode and the anode respectively.

Explanation

To solve the question about the gases collected during the electrolysis of acidified water, we can follow these steps:

### Step 1: Understand the process of electrolysis
Electrolysis is a chemical process that uses electricity to break down a compound into its components. In the case of acidified water, the water (H₂O) is broken down into hydrogen and oxygen gases.

### Step 2: Identify the electrodes
In electrolysis, there are two electrodes: the cathode (negative electrode) and the anode (positive electrode).
