"The Effect of Salt on the Boiling Point of Water"
How does adding salt to water affects it's boiling point?
In this paper, a newly proposed model based on solvation between pure solvent and salt for prediction of salt effect on vapor–liquid equilibria is presented by using only the vapor pressure depression data of pure solvent+salt systems that compose the mixed solvent with salt system
200 mL of distilled water,
5grams of salt,
2 ring clamps,
1. Boil 200ml of distilled water on a beaker.
2. Measure the temperature of the boiling water. Record the highest temperature reading.
3. Measure out table salt using a digital scale.
4. Add the measured salt to the boiling water and stir.
5. Measure the temperature of the boiling water with the salt in it. Record the highest temperature reading.
6. Repeat it now with two spoons of salt.
Observations and Collecting Data:
Qualitative and Quantitative:(Distilled Water)
We started observing the distilled water. In just 2 minutes, tiny bubles appeared. In about 3 minutes the temperature was 45°C, more tiny bubbles. It started smoking and mist is starting to form in the container. The smoke are rising in just about 7 minutes. In 8 minutes more smoke are rising at 60°C. In 11 minutes every molecules in the beaker went or stick to the thermometer. In 14 minutes the temperature was at 80°C. When it was 18 minutes, bigger bubbles appeared and in 20 minutes the boiling point starts.We removed the water from the heat. The water decreased about 198 mL
Qualitative and Quantitative (Distilled water with Salt)
When the salt was added to boiling water it bubbled up more, and then stopped boiling. Shortly afterwards, it boiled again.
If the thermometer extends... [continues]
