The Colorful World of Indicators: Discovering the Pink Indicator

Indicators are substances that are used to determine the pH of a solution. They are a critical component in a variety of scientific experiments. When it comes to indicators, the color of the indicator can tell us a lot about the pH of the solution. One of the most common indicators is pink in basic medium - the pink indicator.

What is an Indicator?

An indicator is a substance that changes color when it comes into contact with an acid or a base. It is used to measure the pH of a solution, which is a measure of the concentration of hydrogen ions in the solution. The pH scale ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most basic. When an indicator comes into contact with an acid or a base, it will react in a way that can be observed - usually by a change in color.

Which of the Following Indicators is Pink in Basic Medium?

The pink indicator is one of the most commonly used indicators. It is a compound called phenolphthalein, and it is pink in basic medium. In acidic solutions, it is colorless. This makes it easy to distinguish between acid and base solutions, as the pink color of the indicator can tell us that the solution is basic.

How Does the Pink Indicator Work?

The pink indicator works by changing color when it comes into contact with an acid or base. In basic solutions, the phenolphthalein molecules are deprotonated and become charged. This causes the molecules to absorb visible light, resulting in the pink color. In acidic solutions, the phenolphthalein molecules are protonated and remain colorless.

Applications of the Pink Indicator

The pink indicator is used in a variety of scientific experiments and applications. It is widely used in titrations, which are experiments that measure the concentration of a solution. It is also used in the classroom to teach students about the pH scale and how to distinguish between acid and base solutions. In addition, it is used in the laboratory to measure the pH of solutions and to detect the presence of acids and bases.

Conclusion

The pink indicator is one of the most commonly used indicators. It is pink in basic solutions and colorless in acidic solutions, making it easy to distinguish between acid and base solutions. It is widely used in titrations, in the classroom, and in the laboratory. So, the answer to the question "Which of the following indicators is pink in basic medium?" is the pink indicator.
