The Vietnamese word "kết tủa" is primarily used in the field of chemistry and translates to "precipitate" in English.

Basic Explanation:

In chemistry, "kết tủa" refers to a solid that forms and separates from a liquid mixture. This usually happens when two solutions are mixed together, and a chemical reaction occurs, causing a substance that is not soluble in the liquid to come out as a solid.

Usage Instructions:

You can use "kết tủa" when discussing chemical reactions, especially when you want to describe the formation of a solid from a solution. It is commonly used in laboratory settings, educational contexts, and scientific discussions.

Example:

• Khi ta trộn dung dịch natri clorua với dung dịch bạc nitrat, sẽ xảy ra phản ứng hóa học tạo ra kết tủa bạc clorua. (When we mix sodium chloride solution with silver nitrate solution, a chemical reaction occurs that produces silver chloride precipitate.)

Advanced Usage:

In more advanced discussions, "kết tủa" can also refer to the process of precipitation in various contexts, such as environmental science, where it can describe how certain substances settle in water bodies or how they are removed from solutions in wastewater treatment.

Word Variants:

• The verb form: "kết tủa hóa" means "to precipitate" or "to form a precipitate."
• Related noun: "chất kết tủa" refers to "precipitated substance" or "precipitate."

Different Meanings:

While "kết tủa" primarily refers to precipitation in a chemical sense, it can also be used metaphorically in literature or conversation to describe the idea of something that emerges or becomes clear after a complex process.

Synonyms:

• "Chất lắng" (settled substance) can sometimes be used interchangeably, especially when referring to substances that settle at the bottom of a container, though it is less specific to the chemical reaction context.
