Understanding Solutions, Solubility, and Mixtures
A dissolvent is a substance that is capable of dissolving other substances. It is usually a liquid, but it can also be a gas or a solid. The dissolvent is the solvent that is used to dissolve the solute (the substance being dissolved) and form a homogeneous solution. Common examples of dissolvents include water, ethanol, acetone, and hexane.
Ques: What is solubility ?
Ans: Solubility is the ability of a substance to dissolve in another substance. It is a measure of how much of the solute can be dissolved in a given amount of dissolvent at a given temperature and pressure. The higher the solubility of a substance, the more of it that can be dissolved in a given amount of dissolvent. Solubility is an important property of substances because it determines whether or not they can be mixed together to form a solution.
Ques: What is saturated solution ?
Ans: A saturated solution is a solution that contains the maximum amount of solute that can be dissolved in a given amount of dissolvent at a given temperature and pressure. In other words, it is a solution that is fully saturated with the solute. When more solute is added to a saturated solution, no more of it will dissolve, and the solution will become supersaturated.
Ques: What is supersaturated solution ?
Ans: A supersaturated solution is a solution that contains more solute than a saturated solution. It is formed when a solution is prepared by adding more solute to a saturated solution than it can hold. The excess solute will not dissolve and will remain in the solution as a precipitate or crystals. Supersaturated solutions are metastable and can crystallize over time, losing their supersaturated state.
Ques: What is solvent ?
Ans: A solvent is a substance that is capable of dissolving other substances. It is usually a liquid, but it can also be a gas or a solid. The solvent is the substance that does the dissolving, and it is the solvent that determines the properties of the solution. Common examples of solvents include water, ethanol, acetone, and hexane.
Ques: What is solution ?
Ans: A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another substance (the solvent). Solutions can be formed by dissolving a solute in a solvent, and they can be used to mix and transport substances. Solutions are important in many areas of life, including chemistry, biology, medicine, and engineering.
Ques: What is homogeneous mixture ?
Ans: A homogeneous mixture is a mixture that has the same composition and properties throughout. In other words, it is a mixture where all the components are evenly mixed together and there are no visible boundaries or layers. Homogeneous mixtures can be solutions, suspensions, or colloids, and they are commonly used in many areas of life, including cooking, painting, and manufacturing.
Ques: What is heterogeneous mixture ?
Ans: A heterogeneous mixture is a mixture that has different compositions and properties throughout. In other words, it is a mixture where the components are not evenly mixed together and there are visible boundaries or layers. Heterogeneous mixtures can be solutions, suspensions, or colloids, and they are commonly used in many areas of life, including cooking, painting, and manufacturing.
Ques: What is colloid ?
Ans: A colloid is a heterogeneous mixture where one substance (the dispersed phase) is dispersed throughout another substance (the continuous phase). Colloids are typically made up of microscopic particles that are suspended in the continuous phase, and they can be found in many areas of life, including food, medicine, and industry. Examples of colloids include milk, gelatin, and whipped cream.
Ques: What is suspension ?
Ans: A suspension is a heterogeneous mixture where solid particles are suspended in a liquid. The particles can be seen with the naked eye, and they can settle out over time if the mixture is left undisturbed. Examples of suspensions include mud, paint, and blood.
Ques: What is emulsion ?
Ans: An emulsion is a heterogeneous mixture where two or more liquids are mixed together to form a stable solution. Emulsions are commonly used in many areas of life, including cooking, painting, and manufacturing. Examples of emulsions include mayonnaise, lotion, and margarine.
