Solubility and Ionic Compounds Concepts

Mr. Riley explains the progression from identifying major entities in a solution to forming chemical equations, focusing on dissociation, ionization, and dispersion. Soluble ionic compounds dissociate into ions, strong acids ionize, and soluble molecular compounds disperse. The video includes examples like magnesium nitrate and sulfuric acid, emphasizing the importance of solubility and balancing equations.

What are the three types of chemical equations discussed in the video?

• Dissociation, Ionization, Dispersion

• Synthesis, Decomposition, Combustion

• Single Replacement, Double Replacement, Neutralization

• Oxidation, Reduction, Precipitation

What happens to soluble ionic compounds when they are placed in water?

• They form a precipitate

• They dissociate into ions

• They remain unchanged

• They combust

Which of the following is an example of a soluble ionic compound?

• Iron oxide

• Sodium chloride

• Magnesium nitrate

• Calcium carbonate

What is the behavior of low solubility ionic compounds in water?

• They ionize

• They disperse

• They remain solid

• They dissociate into ions

What happens to strong acids when they are added to water?

• They dissociate into ions

• They ionize

• They form a precipitate

• They combust

Which of the following is a strong acid?

• Acetic acid

• Sulfuric acid

• Citric acid

• Carbonic acid

What is the behavior of weak acids in water?

• They ionize completely

• They combust

• They remain solid

• They disperse without ionizing

Which of the following is a characteristic of molecular compounds in water?
