Copy and complete the following sentences? With platinum electrodes hydrogen is liberated at the — and oxygen at the_____ during the electrolysis of acidified water.

Explanation

To complete the sentences, we need to understand the process of electrolysis of acidified water using platinum electrodes. Here’s a step-by-step solution:

1. **Identify the Electrolysis Process**: Electrolysis involves passing an electric current through a liquid (in this case, acidified water) to cause a chemical change.

2. **Understand the Role of Electrodes**: In electrolysis, there are two electrodes: the anode (positive electrode) and the cathode (negative electrode).

3. **Determine the Products at Each Electrode**:
- At the **cathode** (negative electrode), reduction occurs. Here, hydrogen ions (H⁺) gain electrons to form hydrogen gas (H₂).
