Question

Запропонуйте спосіб розділення сумішей : а) кухонної солі та піску б) води та олії в) води та спирту Поясніть, які властивость речовин ви при цьому використовували ДОПОМОЖІТЬ, БУДЬ ЛАСКА!!!

Answer 1

А) 1. Додавання до суміші води і розмішування. 
2. Відділення піску від розчину солі фільтруванням. 
3. Випаровування води із розчину і кристалізація солі.
б) виморожування, фільтрування
в)випаровування, дистиляція
Властивості:
а) розчинність солі в воді та те що сіль не випарується разом з водою
б) олія замерзая при значно більшій температурі чим вода, тому коли вода замерзне ми зможемо злити олію 
в) менша температура кипіння спирту тому  спирт випарується швидше ніж вода

Separation of Mixtures: Kitchen Salt and Sand

To separate a mixture of kitchen salt and sand, you can use the difference in their physical properties. One common method is to use the property of solubility. Here's a step-by-step procedure:

1. Dissolve the mixture in water: Add water to the mixture of salt and sand and stir it well. The salt will dissolve in water, while the sand will remain insoluble.

2. Filtration: Pour the mixture through a filter paper or a sieve. The sand particles, being insoluble, will be retained on the filter paper or sieve, while the salt solution will pass through.

3. Evaporation: Collect the salt solution that has passed through the filter paper or sieve. Then, heat the solution to evaporate the water. As the water evaporates, the salt will crystallize and can be collected.

4. Collection of sand: The sand that was retained on the filter paper or sieve can be collected and dried for further use.

By using the difference in solubility between salt and sand, we can separate them effectively. The solubility of salt in water allows it to dissolve, while the insolubility of sand allows it to be retained during filtration [[1]].

Separation of Mixtures: Water and Oil

To separate a mixture of water and oil, you can utilize their difference in density. Here's a common method:

1. Funnel Separation: Pour the mixture of water and oil into a funnel. Due to the difference in density, the oil, being less dense, will float on top of the water.

2. Decantation: Allow the mixture to settle for some time. The oil will form a distinct layer on top of the water. Carefully open the stopcock or remove the stopper from the funnel and let the water drain out. Be cautious not to disturb the oil layer.

3. Collection: Collect the oil that has been separated from the water. You can use a separate container to store the oil.

The separation of water and oil is based on their difference in density. Oil, being less dense, floats on top of water, allowing for easy separation [[2]].

Separation of Mixtures: Water and Alcohol

To separate a mixture of water and alcohol, you can utilize their difference in boiling points. Here's a common method:

1. Distillation: Heat the mixture in a distillation apparatus. The boiling point of alcohol is lower than that of water. As the mixture is heated, the alcohol will vaporize first.

2. Condensation: The alcohol vapor will rise through the distillation apparatus and reach a condenser, where it will cool down and condense back into liquid form.

3. Collection: Collect the condensed alcohol, which has been separated from the water. The water will remain in the distillation flask.

The separation of water and alcohol is based on their difference in boiling points. By heating the mixture and condensing the vapor, we can separate the two components effectively [[3]].

In summary, the separation of mixtures can be achieved by utilizing the differences in physical properties of the substances involved. In the case of kitchen salt and sand, solubility in water is used. For water and oil, density is utilized. And for water and alcohol, the difference in boiling points is employed. These methods allow for the effective separation of the components of the mixtures.
