Solubility

Mr. Anderson explains solubility, focusing on how salts dissolve in water and the factors affecting this process. He introduces the concept of reversible reactions and the solubility product constant (KSP), which measures solubility. The video covers factors like delta G, enthalpy, and entropy, and uses simulations to demonstrate KSP values. Real-world applications, such as seawater and acid mine drainage, are discussed. The video concludes with learning outcomes, emphasizing the ability to predict solubility and interpret KSP values.

What happens at the atomic level when salt is added to water?

• The salt evaporates.

• The salt remains as a solid.

• The salt forms covalent bonds with water.

• The salt breaks into ions and dissolves.

Which of the following factors does NOT affect solubility?

• pH of the solvent

• Color of the solute

• Temperature

• Delta G

What is the role of KSP in solubility?

• It measures the temperature of a solution.

• It indicates the solubility of a salt.

• It determines the color of a solution.

• It measures the pH of a solution.

How does a low KSP value affect a reaction?

• It shifts the reaction towards the left.

• It makes the reaction irreversible.

• It has no effect on the reaction.

• It shifts the reaction towards the right.

In the context of solubility, what does a high KSP value indicate?

• The salt will evaporate.

• The salt is more likely to remain solid.

• The salt is more likely to dissolve.

• The salt will change color.

Why is it difficult to dissolve more salts in seawater compared to freshwater?

• Seawater is colder.

• Seawater has a higher pH.

• Seawater is less dense.

• Seawater has more ions already present.

What effect does acid rain have on carbonate solubility?

• It increases carbonate solubility.

• It causes carbonate to evaporate.

• It decreases carbonate solubility.

• It has no effect on carbonate solubility.
