Question

Задания. 1. о каких свойствах озона свидетельствует обесцвечивание лакмусовых бу-мажек? 2. Почему В последнем опыте появилосьсинее окрашивание?​

Answer 1

1.  Обесцвечивание лакмусовых бумажек свидетельствует о том, что озон проявляет кислотные  свойства.

2.      Озон окисляет KI до йода в свободном состоянии:

 2I -2ê -окисление - I₂⁰

Крахмальный клейстер в присутствии йода синеет. Это качественная реакция на йод.

Answer 2

Properties of Ozone and Its Effect on Litmus Paper

When ozone comes into contact with litmus paper, it can cause the litmus paper to lose its color. This is because ozone is a powerful oxidizing agent and can react with the dyes present in the litmus paper, causing them to become colorless. The reaction between ozone and the dyes in the litmus paper is a reduction-oxidation (redox) reaction, where ozone acts as the oxidizing agent.

Blue Coloration in the Last Experiment

In the last experiment, the appearance of blue coloration can be attributed to the formation of a different compound. Without further information about the specific experiment, it is difficult to determine the exact cause of the blue coloration. However, it is possible that the reaction between ozone and the substances present in the experiment resulted in the formation of a blue-colored compound.

It is important to note that the specific details of the experiment, including the substances used and the conditions under which the experiment was conducted, would be necessary to provide a more accurate explanation for the blue coloration observed.
