A substance is considered completely soluble if it dissolves entirely in a solvent at a given temperature and pressure, resulting in a homogeneous mixture known as a solution. Table salt (sodium chloride) in water is a common example of a substance that is completely soluble under normal conditions. The degree of solubility can depend on factors such as temperature, pressure, and the chemical nature of the solute and solvent. It's important for various applications, including pharmaceuticals, culinary arts, and chemical engineering.

FAQs & Answers

  1. What is the difference between soluble and completely soluble? Soluble means a substance can dissolve in a solvent to some extent, while completely soluble means it dissolves entirely, forming a homogeneous solution.
  2. What factors affect a substance's solubility? Temperature, pressure, and the chemical properties of both the solute and solvent significantly influence solubility.
  3. Is table salt completely soluble in water? Yes, under normal conditions, table salt (sodium chloride) is considered completely soluble in water.
