How to remove potassium permanganate stain
Potassium permanganate is a common chemical reagent widely used in laboratories and medical fields. However, if potassium permanganate solution is accidentally stained on skin, clothing or other items, its dark purple staining effect is often difficult to remove. This article will give you a detailed introduction to the removal method of potassium permanganate staining, and provide hot topics and hot content on the Internet in the past 10 days as a reference.
1. How to remove potassium permanganate staining
The method for removing potassium permanganate staining varies depending on the object being stained. The following are removal methods for different scenarios:
| dyed objects | Removal method | Things to note |
|---|---|---|
| skin | Use vitamin C solution or lemon juice to wipe | Avoid rubbing vigorously to avoid damaging the skin |
| clothing | Soak in oxalic acid solution or hydrogen peroxide and then clean | Test in an inconspicuous place first to avoid fading of clothing |
| furniture | Wipe with dilute hydrochloric acid or alcohol | Rinse with clean water immediately after wiping to avoid corrosion |
| tiles | Wipe with bleach or baking soda paste | Maintain ventilation to avoid inhaling harmful gases |
2. Principle of potassium permanganate staining
Potassium permanganate is a strong oxidant. Its dyeing principle is to chemically react with the surface of the object through an oxidation reaction to form deep purple manganese oxide. Therefore, the key to removing potassium permanganate staining is to use a reducing agent (such as vitamin C, oxalic acid) or a neutralizing agent (such as hydrochloric acid) to reverse this reaction.
