Front

What is a conjugate acid?

Back

A conjugate acid is the species formed when a base gains a proton (H+).

Front

What is a conjugate base?

Back

A conjugate base is the species that remains after an acid donates a proton (H+).

Front

Identify the conjugate acid in the reaction: CH₃COOH + H₂O → ?

Back

H₃O⁺

Front

Identify the conjugate base in the reaction: CH₃COOH + H₂O → ?

Back

CH₃COO⁻

Front

What determines the strength of an acid?

Back

The strength of an acid is determined by its ability to dissociate in water and donate protons.

Front

What is the relationship between acid strength and dissociation?

Back

Stronger acids dissociate more completely in solution, producing more H⁺ ions.

Front

List the following acids in order of increasing strength: hydrocyanic, hypochlorous, citric, acetic.

Back

hydrocyanic, hypochlorous, citric, acetic

Front

What is the conjugate acid of NH₃?

Back

NH₄⁺

Front

What is the significance of the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, with lower values indicating higher acidity.

Front

How does the dissociation of an acid affect its pH?

Back

The more an acid dissociates, the more H⁺ ions are produced, resulting in a lower pH.
