On adding salt to water while boiling, the boiling point of water is ....
Understanding Boiling Point Elevation
When salt is added to boiling water, a phenomenon known as boiling point elevation occurs. Here’s a detailed explanation:
What Happens When Salt is Added?
- When salt (sodium chloride) is dissolved in water, it dissociates into sodium (Na+) and chloride (Cl-) ions.
- These ions interfere with the formation of vapor bubbles, which are necessary for boiling to occur.
Impact on Boiling Point
- The presence of salt in water requires a higher temperature for the water molecules to gain enough energy to escape into the air as vapor.
- As a result, the boiling point of the solution increases. This means that the water will boil at a temperature higher than 100°C (212°F).
Real-World Applications
- This principle is utilized in cooking, as adding salt to water can help food cook more quickly at a higher temperature, although the effect is minimal in everyday cooking.
- It is also significant in various scientific and industrial processes where precise temperatures are necessary.
Conclusion
- Therefore, the correct answer is **(a) increased**; adding salt to water while boiling raises its boiling point, making it necessary to reach a greater temperature for the water to boil.
