Acid-Base Reactions in Solution: Crash Course Chemistry #8

What is the primary cause of the sulfuric acid that contributes to acid rain, as mentioned in the video?

• Volcanic eruptions

• Emissions from coal-fired power plants

• Automobile exhaust

• Natural decomposition of organic matter

Which of the following describes a common property of acids?

• They taste bitter and feel slippery.

• They are excellent at dissolving substances and taste sour.

• They are typically found in antacids.

• They are always harmless.

According to the Bronsted-Lowry definition, what is a base?

• Anything that tastes bitter.

• Anything that donates a proton.

• Anything that accepts a proton.

• Anything that neutralizes an acid.

When an acid donates a proton to water in an aqueous solution, what ion is formed from the water molecule?

• Hydroxide ion (OH-)

• Hydrogen ion (H+)

• Hydronium ion (H3O+)

• Chloride ion (Cl-)

What is a key difference between Arrhenius bases and other bases discussed in the video?

• Arrhenius bases always contain hydroxide, while other bases might not.

• Arrhenius bases accept protons, while other bases donate protons.

• Arrhenius bases are always strong, while other bases are weak.

• Arrhenius bases are found in water, while other bases are not.

What chemical compound is formed when sulfur dioxide, oxygen, and water combine in the atmosphere, leading to acid rain?

• Carbonic acid

• Hydrochloric acid

• Sulfuric acid

• Nitric acid

Which of the following is a known negative effect of acid rain?

• It makes plants grow faster.

• It strengthens metal structures.

• It damages limestone and acidifies water supplies.

• It increases the oxygen levels in lakes.

How can power plants reduce the amount of sulfur dioxide released into the atmosphere?

• By burning more coal.

• By releasing smoke higher into the atmosphere.

• By passing smoke stack gases through a limestone slurry.

• By converting sulfur dioxide into carbon dioxide.
