Acids and Bases Quiz

What are the properties of acids?

• Acids have a sour taste, turn blue litmus paper red, and react with metals to produce hydrogen gas.

• Acids have a sweet taste

• Acids have a replacable helium atom

• Acids turn red litmus paper blue

Explain the properties of bases.

• Bases feel rough to the touch

• Bases have a bitter taste, feel slippery, turn red litmus paper blue, and have a pH greater than 7.

• Bases have a sweet taste

• Bases turn blue litmus paper red

Provide examples of common bases.

• Hydrochloric acid (HCl)

• Carbon dioxide (CO2)

• Sodium hydroxide (NaOH), ammonia (NH3), potassium hydroxide (KOH)

• Sulfuric acid (H2SO4)

What happens in a neutralization reaction?

• An acid reacts with a base to form water and sugar.

• A base reacts with a base to form water and a salt.

• An acid reacts with an acid to form water and a salt.

• An acid reacts with a base to form water and a salt.

Give examples of indicators and their colors in acidic and basic solutions.

• Litmus - Blue (acidic), Red (basic); Phenolphthalein - Pink (acidic), Colorless (basic); Methyl Orange - Yellow (acidic), Red (basic)

• Litmus - Red (acidic), Blue (basic); Phenolphthalein - Colorless (acidic), Pink (basic); Methyl Orange - Red (acidic), Yellow (basic)

How do acids and bases differ in terms of pH?

• Acids and bases have the same pH value

• Acids are neutral substances with a pH of 7

• Acids have a pH less than 7, while bases have a pH greater than 7.

• Acids have a pH greater than 7, while bases have a pH less than 7

Explain the concept of strong acids and bases.

• Strong acids and bases do not react with other substances.

• Strong acids and bases completely dissociate into ions in solution.

• Strong acids and bases have low solubility in water.

• Strong acids and bases are weak electrolytes.

How do acids and bases react with each other in a neutralization reaction?

• Acids and bases react by exploding when mixed together

• Acids and bases react by forming a solid substance

• Acids and bases react by producing light and heat

• Acids and bases react by combining to form water and a salt.

What are the products of a neutralization reaction?

• Salt and water

• Sugar and oil

• Gas and solid

• Acid and base

Describe the role of acids and bases in the human body.

• Acids and bases have no impact on the body's pH balance

• Acids are only harmful in the body and should be avoided

• Acids aid in digestion, muscle function, and energy production, while bases neutralize excess acids to maintain pH balance.

• Bases are responsible for breaking down proteins in the body
