Purple medicine, a familiar chemical to many, finds extensive use across various domains. However, are you acquainted with its composition, properties, and applications? Let's delve into the realm of purple medicine through this elucidating piece on Mytour Blog!
What is Purple Medicine?
Purple medicine, also known as phenolphthalein, stands as a ubiquitous chemical in daily life, boasting numerous applications across diverse fields. Its scientific nomenclature, C20H14O4, characterizes it as a white powder insoluble in water but soluble in alcohol or alkaline solutions. Renowned for its acid-base indicator properties, it undergoes color changes in response to varying pH levels in solutions.

Purple medicine is a potent oxidizing agent capable of explosion or combustion upon contact with organic substances. It exists as deep purple crystals with a molecular weight of 158.034 g/mol and a density of 2.703 g/cm3. This type of medicine dissolves in water at a concentration of approximately 6.38 g/100ml at 20 °C and 25 g/100ml at 65 °C but is insoluble in alcohol and organic solvents.
The medicine is susceptible to decomposition at temperatures exceeding 240°C and finds widespread use across various fields such as medical, pharmaceutical, and food industries, available in the market in crystal or powder form.

So, what are the functions of purple medicine? How should this type of medicine be applied in daily life to achieve effectiveness? The answers below will help you resolve any queries.
Sterilization, Bactericidal Properties
This substance exhibits potent oxidizing properties, capable of eradicating various harmful microorganisms affecting human health. It can be used for disinfecting and cleaning water, equipment, fruits, vegetables, and cooking utensils. As a result, we can prevent diseases caused by contaminated water and food, such as dysentery, diarrhea, enteritis, infections, etc. However, when using, attention must be paid to the concentration and exposure time of the solution as it can cause irritation to the skin, mucous membranes, and eyes. Additionally, purple medicine is ineffective when there is an excess of organic matter in the water source. Therefore, we need to adhere to the manufacturer's or medical guidelines to ensure safety and effectiveness.

Potassium permanganate purple medicine is a highly potent oxidizing agent, capable of reacting with various organic toxic substances in water such as phenol, formaldehyde, cyanide, humic acid... When the reaction occurs, the toxic substances will be transformed into non-toxic or less toxic compounds such as carbon dioxide, water, ammonia... As a result, the water source will be cleaner and safer for use.
The medicine can also help improve the color, odor, and taste of water by removing pollutants and dirt. However, when used for water purification, we need to accurately calculate the amount of purple medicine needed because using too much can cause over-oxidation, making the water cloudy and unpleasant-smelling.
Medical Use
This type of medicine can be used to clean wounds, prevent infections, dry out water, pus, or blisters. The medicine can also help alleviate symptoms of eczema, dermatitis, acne, and other fungal infections on the hands and feet. A simple and effective way to use purple medicine is to soak your feet or hands in a diluted solution of purple medicine for about 15 minutes. This will help disinfect, clean, and soothe the skin.
However, when using, we need to pay attention to the dosage and exposure time of the solution as the medicine can cause skin, mucous membrane, and eye irritation if used excessively or for too long.
Treating Fish Diseases
Ornamental fish are visually appealing and fascinating pets, but they are also susceptible to diseases caused by infections, bacteria, fungi... If not treated promptly, these diseases can lead to the death of ornamental fish and spread to other fish. Purple medicine is a type of oxidizing and disinfecting medicine that can help treat skin, scale, eye, and mouth diseases in ornamental fish. The medicine can also help improve water quality in fish tanks by removing organic substances such as bacteria, algae, and dirt...

Let's explore more applications of the medicine in treating domestic wastewater, especially in aquaculture and daily life.
Applications in Aquaculture
This type of medicine is commonly used in aquaculture. Below are 2 methods that many people often use to treat wastewater in aquaculture.
- Method 1: Sprinkle about 2mg/l of purple medicine onto the pond surface and leave it for 8 to 12 hours. If after this time, the water color changes from purple to pink, it means the dosage is sufficient. If after this time, the water color changes to brown, it means the dosage of the medicine is insufficient and an additional 1 - 2mg/l is needed.
- Method 2: Bathe the fish in a purple medicine solution with a concentration of 10mg/l for 30 minutes. Then, soak the fish in a saltwater solution with a concentration of 0.2 - 1% for a few days or 1 week depending on the type of fish. When using this method, we need to pay special attention to significant changes in the fish to be able to promptly address any abnormal signs and prevent unfortunate consequences that may occur.
Applications of Purple Medicine in Daily Life and Aquaculture (Source: Internet)Using Purple Medicine in Daily Life
Depending on the purpose of use, you can use different dosages. Some reference dosages are as follows:
- To eliminate odor and enhance taste, we can use a maximum dosage of 20mg/l.
- To disinfect bacteria, we can use a dosage ranging from 2 to 4mg/l.
- To disinfect viruses, we can use a dosage of 50mg/l.
When using this type of medicine in household water, we need to pay attention to the amount of organic matter in the water because organic matter will reduce the effectiveness of the medicine. If the water is heavily contaminated with iron, it will have a foul smell or strange taste. In that case, we need to use potassium permanganate to oxidize iron and manganese and remove odor-causing compounds.
During oxidation, iron and manganese in the water will turn the water black or brownish-orange. Therefore, we need to accurately calculate the amount of water in the pond and the amount of medicine needed to avoid waste or ineffective treatment. This type of medicine is usually stored in dry, cool places away from sunlight because direct sunlight can degrade the medicine.
