Question

Describe how you would obtain a beaker of pure water from salty water .(this answer needs to be long, please draw a labelled f the equipment and explain how each part works- what is this technique called ).

Answer 1

To obtain pure water from salty water, you can use a technique called distillation. This involves boiling the salty water and collecting the vapor that is produced. The vapor is then condensed and collected as pure water.

Step-by-step explanation:

To obtain a beaker of pure water from salty water, you can use a technique called distillation. Distillation involves boiling the salty water and then collecting the vapor that is produced. The vapor is condensed and collected as pure water in a separate container.

To perform distillation, you would need the following equipment:

• A distillation flask, which is where the salty water is heated
• A condenser, which cools down the vapor and turns it back into liquid
• A receiving flask, where the pure water is collected
• A heat source, such as a Bunsen burner or hot plate

The process of distillation works by taking advantage of the differences in boiling points between water and salt. When you heat the salty water, the water molecules will begin to evaporate first due to their lower boiling point compared to salt.

The vapor rises and enters the condenser, where it is cooled down and returns to a liquid state, leaving behind the salt. The pure water then drips into the receiving flask.

This technique allows you to separate the pure water from the salts and impurities present in the salty water, resulting in a beaker of pure water.
