What Is a Nonelectrolyte?
Non-electrolyte refers to a compound that cannot conduct electricity in an aqueous solution or in a molten state. Non-electrolytes are compounds that are covalently bonded. Except for carboxylic acids and their salts, phenols, amines, etc., most organic compounds are non-electrolyte. This concept is relative to electrolytes. Non-electrolytes are typically covalently bonded compounds that do not undergo ionization reactions in aqueous solutions. Except for carboxylic acids and their salts, phenols, and amines, most organic compounds are non-electrolyte, such as sucrose, glycerol, and ethanol. Among inorganic compounds, only certain non-metal halides and all non-metal oxides (except water) are non-electrolytes.
- The concept of non-electrolyte is relative to
- 1.
- Electrolyte and non-electrolyte
- Guided reclassification can form a classification chart of substances in the student's brain. Using the classification chart can more systematically remember related knowledge, and it is easy to judge which are electrolytes and which are non-electrolytes. For example, based on the knowledge provided below:
- Electrolyte
- Divided into strong electrolytes and weak electrolytes.
- Strong electrolytes include strong acids (such as HCl, HNO3, H2SO4, HClO4, etc.), strong bases (such as KOH, NaOH, Ca (OH) 2, etc.) and most salts.
- Weak electrolytes include weak acids, weak bases, individual salts and water.
- 2. Non-electrolyte
- Organic substances other than organic acids, non-metal oxides, non-metal hydrides. Example: NH 3 [3]
- Substances that are neither electrolytes nor non-electrolytes
- All mixtures of concentrated sulfuric acid, dilute sulfuric acid, simple substance and common salt solution, air, etc. are neither electrolyte nor non-electrolyte [4] .
