Bronsted Lowry Acids and Bases Reaction Predictions

What is the definition of a Bronsted-Lowry acid?

• A substance that donates a proton (H+)

• A substance that accepts a proton (H+)

• A substance that has a high pH level

• A substance that releases electrons

What is the definition of a Bronsted-Lowry base?

• A substance that can change color in a chemical reaction

• A substance that can accept a proton

• A substance that can conduct electricity

• A substance that can donate a proton

Give an example of a conjugate acid-base pair.

• Na+ / OH-

• H2O / H2

• HCl / Cl-

• NH3 / NH4+

Explain the concept of conjugate acid-base pairs.

• Conjugate acid-base pairs are two substances related to each other by the transfer of a proton.

• Conjugate acid-base pairs are substances that share electrons

• Conjugate acid-base pairs are substances that are not involved in proton transfer

• Conjugate acid-base pairs are substances that have no relationship to each other

What are amphoteric substances?

• Substances that can only act as bases

• Substances that can only act as acids

• Substances that are completely neutral

• Substances that can act as both acids and bases

Provide an example of an amphoteric substance.

• Sodium

• Oxygen

• Water

• Iron

How do Bronsted-Lowry acids donate protons?

• By absorbing them from a solution

• By storing them in a solid form

• By releasing them into a solution

• By converting them into electrons

How do Bronsted-Lowry bases accept protons?

• By accepting a pair of electrons

• By donating a pair of electrons

• By releasing a pair of electrons

• By donating a proton

Explain the relationship between a substance and its conjugate base.

• They are related by the formation of a covalent bond.

• They are related by the transfer of a proton.

• They are related by the release of energy.

• They are related by the sharing of electrons.

What is the role of water in the Bronsted-Lowry theory?

• Water only acts as a base in the Bronsted-Lowry theory

• Water can act as both an acid and a base.

• Water only acts as an acid in the Bronsted-Lowry theory

• Water has no role in the Bronsted-Lowry theory
