Congo red test paper - Names and Identifiers
Congo red test paper - Introduction
Congo red paper is a chemical test paper commonly used to detect the pH and chromatin of substances. The following is a description of its nature, use, preparation and safety information:
Nature:
Congo red paper is made from fibrous paper or filter paper soaked in a solution of Congo red dye. It is red and can change color according to the acid-base change of the solution.
Use:
Congo red paper is widely used in chemical laboratories and industrial production. It is often used to test the acidity and alkalinity of the solution, and can be used to detect dyes, proteins and ions.
Method:
The method of making Congo red paper is relatively simple. First, soak the fiber paper or filter paper in a solution of Congo red dye to allow it to fully absorb the dye. Subsequently, the test paper is allowed to dry so that it can accurately respond when used.
Safety Information:
When using Congo red paper, you need to pay attention to the following security matters:
1. Avoid direct contact with skin and eyes to avoid irritation. In case of contact, rinse immediately with plenty of water.
2. Do not inhale the dust of Congo red paper to avoid irritation or allergic reaction.
3. Congo red dye can be toxic and should be stored in a dry, dark, airtight container. Avoid mixing with other chemicals.
4. Be careful to avoid touching the fire source during use to prevent the test paper from catching fire.
5. During use, it is best to wear protective gloves and safety glasses.
In General, Congo red paper is a commonly used chemical reagent with a wide range of applications. Pay attention to operational safety when using it, and follow appropriate safety measures when storing and handling it.
