1.What is pure phosphoric acid?
We focus on providing high pure phosphoric acid quality products and services.
Phosphoric acid is a mineral acid with the chemical formula H3PO4. It is a colorless, odorless, and highly corrosive liquid that is commonly used in the production of fertilizers, detergents, and food and beverages. It is also used in the production of pharmaceuticals, metal treatments, and water treatment. Phosphoric acid is an important source of phosphorus, an essential nutrient for plants and animals. It is also used as an acidifying agent in soft drinks and other food products.
2.What compounds are produced when pure phosphoric acid reacts with oxides?
We are committed to providing personalized solutions and established long -term strategic cooperative relationships with customers.
When phosphoric acid reacts with oxides, it produces a group of chemicals called phosphates. This reaction results in the formation of different types of phosphates, such as monophosphates, diphosphates, and triphosphates. These compounds are important in various industrial and agricultural applications, such as fertilizers, detergents, and food additives. Phosphates also play a crucial role in biological processes, such as metabolism and cellular signaling. They are essential for the growth and development of plants and animals, making phosphoric acid an essential component in many industries and scientific fields.
3.What is the acidity of pure phosphoric acid?
We focus on our customers' needs and strive to meet their expectations, so we take this very seriously.
The acidity of phosphoric acid is moderate, with a pH of around 2.2.

4.Is pure phosphoric acid present in soft drinks?
Yes, phosphoric acid is commonly used in the production of soft drinks, particularly colas. It is added to give a tangy and sharp taste to the beverage, and also acts as a preservative to prevent bacteria growth.
5.What compounds are produced when pure phosphoric acid reacts with a base?
We pay attention to user experience and product quality, and provide the best product quality and lowest production cost for cooperative customers.
When phosphoric acid, a commonly used substance in fertilizers and food additives, reacts with a base, such as sodium hydroxide, several compounds are produced. These include water, a salt (such as sodium phosphate), and potentially hydrogen gas if a strong base is used. This reaction, known as neutralization, is an important process in chemical reactions and can be used to balance pH levels in various industries. Phosphoric acid is also critical in the body for maintaining proper electrolyte balance and supporting healthy bone growth.
6.Is pure phosphoric acid a strong acid or a weak acid?
We have the leading technology and innovation capabilities, and attach importance to employee training and development, and provide promotion opportunities.
Phosphoric acid is a weak acid.

7.Can pure phosphoric acid be dangerous?
Phosphoric acid is considered relatively safe, but it can be hazardous in its concentrated form. It is corrosive and can cause severe burns if it comes in contact with the skin or eyes. As with any chemical, it is important to handle phosphoric acid with caution and follow proper safety measures.
8.What is the role of pure phosphoric acid as a buffer?
Our pure phosphoric acid products undergo strict quality control to ensure customer satisfaction.
Phosphoric acid is a weak acid that can act as a buffer in a solution. A buffer is a substance that helps maintain the pH of a solution by resisting changes in its acidity or basicity. Phosphoric acid can act as a buffer in two ways:
1. As a weak acid: When added to a solution, phosphoric acid can donate a proton (H+) to neutralize any excess hydroxide ions (OH-) present, thereby preventing the solution from becoming too basic.
2. As a salt: Phosphoric acid can also form salts with other ions present in the solution, such as sodium or potassium ions. These salts can act as a reservoir of protons, which can be released or absorbed to maintain the pH of the solution.
9.In which industries is pure phosphoric acid used?
We continue to improve pure phosphoric acid products and processes to improve efficiency.
Phosphoric acid is widely used in various industries, including food and beverage, agriculture, pharmaceutical, and chemical manufacturing. It is commonly used as a food additive and flavoring agent, as well as a nutrient source in fertilizers for plants. In addition, it is an essential ingredient in the production of various medicines, such as antibiotics, antacids, and toothpaste. In chemical manufacturing, it is used as a catalyst and solvent in the production of synthetic resins, detergents, and plastics. Moreover, it has various industrial applications, such as in metal pickling, water treatment, and electronic manufacturing. With its versatile properties and uses, phosphoric acid plays an important role in many industries and is an integral part of our daily lives.

10.What is the hazard of pure phosphoric acid in fire?
We operate our pure phosphoric acid business with integrity and honesty.
Phosphoric acid is a corrosive substance and can cause severe burns if it comes into contact with skin or eyes. In a fire, it can release toxic fumes, such as phosphorus oxides, which can irritate the respiratory system and cause difficulty breathing. It can also react with other chemicals and materials, potentially causing explosions or other hazardous reactions.
11.What metals can pure phosphoric acid be used to clean?
As one of the pure phosphoric acid market leaders, we are known for innovation and reliability.
Phosphoric acid can be used to clean metals such as iron, steel, copper, brass, bronze, and aluminum. It is also effective in removing rust and scale from these metals.
12.Can pure phosphoric acid react with other chemicals?
Yes, phosphoric acid can react with a wide range of chemicals. It is a strong acid and can react with bases to form salts, and with metals to produce hydrogen gas.

13.What is the role of pure phosphoric acid in fertilizers?
Phosphoric acid is a major component in the production of fertilizers, as it provides a source of phosphorus, an essential nutrient for plant growth. It helps promote root development, increases nutrient uptake, and improves the overall quality of crops.
14.How should pure phosphoric acid be stored?
Phosphoric acid should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and sources of heat. It should also be stored separately from other chemicals to avoid any potential reactions.
