Chapter 4 Problems1 Which Of These Compounds Is Astrong Electrolyte

Identify the compound that functions as a strong electrolyte among the given options: Water (H2O), Oxygen (O2), Sulfuric acid (H2SO4), Glucose (C6H12O6), and Acetic acid (CH3COOH).

Strong electrolytes are substances that completely dissociate into ions in aqueous solution, resulting in high conductivity. Typically, ionic compounds and strong acids or bases are strong electrolytes.

Sulfuric acid (H2SO4) is a well-known strong acid. When dissolved in water, it dissociates entirely into H+ and SO4²⁻ ions, contributing to high electrical conductivity. Water and oxygen are not electrolytes; glucose is a nonelectrolyte because it does not dissociate into ions in solution.

Paper For Above instruction

Sulfuric acid (H2SO4) is a strong electrolyte among the given compounds. It is classified as a strong acid, which means it dissociates completely in aqueous solutions, providing a high concentration of ions for electrical conductivity. This behavior aligns with the general characteristics of strong electrolytes, which include soluble salts, strong acids, and strong bases.

In contrast, water (H2O) and oxygen (O2) are covalent molecules with negligible ionization in solution, making them poor conductors and non-electrolytes under typical conditions. Glucose (C6H12O6) is a molecular compound that dissolves in water without ionizing significantly, classifying it as a nonelectrolyte. Acetic acid (CH3COOH) is a weak acid that only partially dissociates, functioning as a weak electrolyte.

Understanding the difference between electrolytes and nonelectrolytes is fundamental in chemistry, especially in the context of solution chemistry and electrochemistry. The complete dissociation of strong acids like sulfuric acid facilitates various industrial applications, including battery operation, manufacturing, and chemical synthesis.
