Rank These Substances In Order Of Increasing Solubility In Water.

Introduction:
In chemistry, solubility is a crucial concept that describes the ability of a substance to dissolve in another substance. Understanding the solubility of various substances in water is essential for myriad applications, ranging from household cleaning to industrial processes. Let’s delve into the world of solubility and explore how different substances fare when mixed with water.

Challenges in Understanding Solubility:
Determining the solubility of a substance in water can be a complex task. Several factors, such as temperature, pressure, and the chemical nature of the substances involved, can influence the outcome. This complexity often leads to confusion and misconceptions regarding the solubility of different substances.

Ranking Substances by Solubility:
To simplify the understanding of solubility, let’s rank some common substances based on their increasing solubility in water. This ranking provides a practical reference for various applications and helps us grasp the concept of solubility more effectively.

Ranking Various Substances:

  1. Sucrose (Table Sugar): Sucrose, the common table sugar we use daily, is highly soluble in water. It readily dissolves, forming sweet solutions.
  2. Sodium Chloride (Table Salt): Sodium chloride, also known as table salt, is another highly soluble substance in water. Its salty taste is familiar to all.
  3. Ethanol (Alcohol): Ethanol, commonly known as alcohol, is moderately soluble in water. It readily mixes with water, forming various alcoholic beverages.
  4. Oxygen: Oxygen, a vital gas for life, is sparingly soluble in water. Its limited solubility affects aquatic life and various industrial processes.
  5. Carbon Dioxide: Carbon dioxide, a greenhouse gas, is slightly soluble in water. It contributes to the formation of carbonic acid, influencing the pH of water bodies.
  6. Hexane: Hexane, a nonpolar hydrocarbon, is practically insoluble in water. Its immiscibility with water makes it useful for various industrial applications.

Conclusion:
Understanding the solubility of substances in water is crucial for various applications. By ranking common substances based on their increasing solubility in water, we gain a practical perspective on their behavior when mixed with water. This knowledge finds applications in fields such as chemistry, biology, and engineering, helping us solve real-world problems and advance scientific understanding.

Rank These Substances in Order of Increasing Solubility in Water

1. Introduction

Solubility is a measure of the ability of a substance to dissolve in a solvent. In this case, the solvent is water. When a substance is soluble in water, it means that it can mix with water and form a homogeneous solution. The more soluble a substance is, the more of it can dissolve in a given amount of water.

2. Factors Affecting Solubility

The solubility of a substance in water depends on several factors, including:

  • Temperature: In general, the solubility of a substance increases as the temperature of the water increases. This is because the higher the temperature, the more energy the water molecules have, and the more likely they are to collide with and dissolve the substance.
  • Pressure: The solubility of a gas in water increases as the pressure of the gas increases. This is because the higher the pressure, the more gas molecules are forced into contact with the water molecules, and the more likely they are to dissolve.
  • Polarity: Polarity is a measure of the difference in electronegativity between the atoms in a molecule. A polar molecule has a partial positive charge on one end and a partial negative charge on the other end. Polar molecules are more soluble in water than nonpolar molecules because they are attracted to the oppositely charged water molecules.

3. Ranking of Substances by Solubility

The following table ranks a number of common substances in order of increasing solubility in water:

Substance | Solubility (g/100 mL)
———|———-
Sucrose | 178.8
Glucose | 95.0
Sodium chloride | 35.7
Ethanol | 100
Acetone | 123
Ethyl ether | 6.9
Benzene | 0.07

4. Applications of Solubility

The solubility of a substance can have a number of important applications, including:

  • Extraction: Solubility can be used to separate substances from a mixture. For example, the solubility of salt in water can be used to separate salt from sand.
  • Purification: Solubility can be used to remove impurities from a substance. For example, the solubility of sugar in water can be used to remove impurities from sugar.
  • Drug Delivery: Solubility can be used to control the delivery of drugs in the body. For example, some drugs are made more soluble so that they can be absorbed more quickly, while other drugs are made less soluble so that they can be released more slowly.

5. Conclusion

Solubility is a fundamental property of matter that has a wide range of applications. By understanding the factors that affect solubility, we can use this knowledge to control and manipulate solubility for a variety of purposes.

6. FAQs

  1. What is the relationship between solubility and temperature?
  • In general, the solubility of a substance increases as the temperature of the water increases.
  1. What is the relationship between solubility and pressure?
  • The solubility of a gas in water increases as the pressure of the gas increases.
  1. What is the difference between polar and nonpolar molecules?
  • Polar molecules have a partial positive charge on one end and a partial negative charge on the other end. Nonpolar molecules do not have any partial charges.
  1. How can solubility be used to separate substances from a mixture?
  • Solubility can be used to separate substances from a mixture by taking advantage of the different solubilities of the substances.
  1. How can solubility be used to control the delivery of drugs in the body?
  • Solubility can be used to control the delivery of drugs in the body by making some drugs more soluble so that they can be absorbed more quickly and other drugs less soluble so that they can be released more slowly.
