Strong acid

The video tutorial explains that a strong acid is one that is fully ionized in solution, with sulfuric acid and hydrochloric acid as examples. It highlights that strong acids completely dissociate into ions. The tutorial also clarifies the difference between the strength of an acid and its concentration, noting that an acid can be both strong and concentrated.

What defines a strong acid in terms of its behavior in solution?

• It does not ionize in solution.

• It fully ionizes in solution.

• It only ionizes in solid form.

• It partially ionizes in solution.

Which of the following is an example of a strong acid?

• Carbonic acid

• Citric acid

• Sulfuric acid

• Acetic acid

What happens to strong acids like sulfuric acid in solution?

• They remain as whole molecules.

• They form a precipitate.

• They completely dissociate into ions.

• They evaporate quickly.

How does the concept of concentration differ from the strength of an acid?

• Concentration and strength are the same.

• Concentration refers to the amount of acid in a solution, while strength refers to the degree of ionization.

• Concentration refers to the color of the acid, while strength refers to its taste.

• Concentration is about the temperature of the solution.

Can an acid be both strong and concentrated? If so, what does this mean?

• No, an acid cannot be both.

• Yes, it means the acid is fully ionized and present in a large amount in the solution.

• Yes, it means the acid is weak and diluted.

• No, it means the acid is only partially ionized.
