Trivia Questions On Acids And Bases!

2.

_____ are solutions containing ions that react with acids or bases to minimize their effects.

Buffers
Hydroxide
Enzymes
Indicators

Correct Answer

A. Buffers

Explanation

Buffers are solutions containing ions that react with acids or bases to minimize their effects. When an acid or base is added to a buffer solution, the buffer components react with the added ions, preventing a large change in pH. This is because buffers are made up of a weak acid and its conjugate base or a weak base and its conjugate acid. The weak acid/base can donate or accept protons, effectively neutralizing the added acid or base and maintaining the pH of the solution within a relatively narrow range.

Which of the following bases can be ingested safely?

Aluminum hydroxide
Sodium hydroxide
Calcium hydroxide
Ammonia

Correct Answer

A. Aluminum hydroxide

Explanation

Aluminum hydroxide can be ingested safely because it is commonly used as an antacid to relieve symptoms of heartburn, indigestion, and upset stomach. It works by neutralizing excess stomach acid, providing relief without causing harm to the body. On the other hand, sodium hydroxide, calcium hydroxide, and ammonia are not safe to ingest as they are highly caustic and can cause severe damage to the digestive system if ingested.

In chemical equations describing ionization, what do double arrows pointing in opposite directions indicate?

The reaction is doubled.
The ionization reaction is incomplete.
The reaction is a strong acid.
There is twice as much product as reactant.

Correct Answer

A. The ionization reaction is incomplete.

Explanation

The double arrows pointing in opposite directions in a chemical equation indicate that the ionization reaction is incomplete. This means that only a portion of the reactants have been converted into products, and there is still some remaining reactant present. It suggests that the reaction can proceed in both forward and reverse directions, with the equilibrium lying towards the side of the reactants.

Which two terms refer to the amount of acid or base dissolved in solution?

Strong and dilute
Strong and weak
Dilute and concentrated
Weak and concentrated

Correct Answer

A. Dilute and concentrated

Explanation

The terms "dilute" and "concentrated" refer to the amount of acid or base dissolved in a solution. A dilute solution contains a small amount of acid or base dissolved in a larger amount of solvent, resulting in a lower concentration. On the other hand, a concentrated solution contains a large amount of acid or base dissolved in a smaller amount of solvent, resulting in a higher concentration.

Which two groups does a soap molecule contain?

Hydronium and hydroxide
Hydroxide and carboxylic acid
Nonpolar carbon chain and salt of a carboxylic acid
Nonpolar nitrogen chain and carboxylic acid

Correct Answer

A. Nonpolar carbon chain and salt of a carboxylic acid

Explanation

A soap molecule is composed of a nonpolar carbon chain and a salt of a carboxylic acid. The nonpolar carbon chain is hydrophobic, meaning it repels water, while the salt of a carboxylic acid is hydrophilic, meaning it attracts water. This unique structure allows soap molecules to interact with both water and oil, making them effective at removing dirt and grease from surfaces.

7.

Which of the following substances contains a base?

Aspirin
Vinegar
Fertilizer
Lemon juice

Correct Answer

A. Fertilizer

Explanation

Fertilizer contains a base because it is typically made up of various compounds that release hydroxide ions (OH-) when dissolved in water. These hydroxide ions are characteristic of bases and can neutralize acids. In contrast, aspirin, vinegar, and lemon juice are all acidic substances. Aspirin is a weak acid, vinegar contains acetic acid, and lemon juice contains citric acid. Therefore, fertilizer is the only substance among the options that contains a base.

8.

A(n) ______ is a substance that produce hydrogen ions in solution.

Salt
Base
Indicator
Acid

Correct Answer

A. Acid

Explanation

An acid is a substance that produces hydrogen ions in a solution. When an acid is dissolved in water, it releases hydrogen ions (H+) which can then react with other substances. Acids are known for their sour taste, ability to corrode metals, and ability to turn blue litmus paper red. Some common examples of acids include hydrochloric acid, sulfuric acid, and acetic acid.

What is a disadvantage of adding phosphates to detergents?

Phosphates cause a detergent to produce scum in hard water.
Detergents with phosphates cannot clean as throughly as those without them do.
Phosphates are corrosive.
Phosphates can cause overgrowth of algae in waterways.

Correct Answer

A. Phosphates can cause overgrowth of algae in waterways.

Explanation

Adding phosphates to detergents can lead to the overgrowth of algae in waterways. When these detergents are washed down drains and into water sources, the phosphates act as a nutrient for algae, causing them to multiply rapidly. This excessive growth of algae can disrupt the balance of aquatic ecosystems, deplete oxygen levels in the water, and harm fish and other aquatic organisms. It can also lead to the formation of harmful algal blooms, which can release toxins into the water and pose a threat to human health. Therefore, the presence of phosphates in detergents is a disadvantage due to its negative impact on waterways.

_____ are organic salts.

Polymers
Titrations
Soaps
Esters

Correct Answer

A. Soaps

Explanation

Soaps are organic salts because they are formed through the reaction of a fatty acid with a base, usually sodium hydroxide or potassium hydroxide. This reaction results in the formation of a salt called a soap, which consists of a long hydrocarbon chain (from the fatty acid) and a polar head (from the base). Soaps are commonly used for cleaning purposes due to their ability to dissolve dirt and oils in water.
