Question

В несколько стаканов налейте окрашенные жидкости:чай,компот,воду ,раствор,приготовленный из нескольких капель зелёнки в воде .В каждый раствор поместите несколько истолчённых таблеток активированного угля и оставьте на некоторое время.Как измениться окраска взятых растворов?На какое свойство угля указывает измен

Answer 1

Растворы обесцветятся.свойство активированного угля-абсорбция-поглощение веществ

Answer 2

Проэкспериментируй ))) действительно,интересно

Answer 3

Experiment with Colored Liquids and Activated Charcoal

To conduct the experiment, follow these steps:

1. Take several glasses and pour different colored liquids into each glass. You can use tea, fruit compote, water, and a solution made by adding a few drops of green dye (such as zelenka) to water.

2. In each solution, place a few crushed tablets of activated charcoal.

3. Leave the glasses undisturbed for some time.

Observations: After some time, you will notice changes in the color of the solutions. The activated charcoal will absorb certain substances from the liquids, causing the color to change.

Explanation: Activated charcoal is a highly porous substance that has the ability to adsorb (not absorb) various substances. When the charcoal comes into contact with the colored liquids, it adsorbs the pigments responsible for the color, resulting in a change in the color of the solution.

The specific color change will depend on the pigments present in the original solution. For example, if you used tea as one of the colored liquids, the activated charcoal will adsorb the brown pigments, causing the solution to become lighter in color. Similarly, in the case of the green dye solution, the charcoal will adsorb the green pigments, resulting in a decrease in the green color intensity.

Conclusion: The experiment demonstrates the adsorption properties of activated charcoal. It can effectively remove certain substances, including pigments, from liquids, leading to a change in color. This property of activated charcoal makes it useful in various applications, such as water purification and medical treatments.

Please note that the specific details of the color changes in the experiment may vary depending on the exact composition of the colored liquids used and the characteristics of the activated charcoal.
