Question

Define impurity. Explain the various sources of impurities.​

Answer 1

Answer:

Hope this answer helps you!

Explanation:

Impurities are chemical substances inside a confined amount of liquid, gas, or solid, which differ from the chemical composition of the material or compound. Impurities are either naturally occurring or added during synthesis of a chemical or commercial product.

The various sources of impurities.:-

Organic Impurities. Organic impurities are often process-related or drug-related pharmaceutical impurities.

Inorganic Impurities. Inorganic impurities often derive from the manufacturing process.

Residual Solvents.

Answer 2

Impurities may be defined as chemical substances that are confined inside a liquid, solid or gas which may be different from the chemical composition of the substance. They either occur naturally or are added during the process of synthesis of any chemical reaction with the help of catalysts.

The various sources of impurities are:

1. Organic Impurities: Organic impurities may be impurities which are added as a drug or in pharmaceutical impurity for which different medicines and drugs are made. Examples include by-products, intermediates, ligands and catalysts.
2. Inorganic Impurities: Inorganic impurities derive from the manufacturing process. The most common inorganic impurity in water is the residuals of ions such as sodium, calcium, and chloride after the purification of water.
3. Residual Solvents:  Residual solvents are often used as catalysts during the synthesis of any reaction.
