What is the Bronsted-Lowry definition of an acid?
Click to flip
The Bronsted-Lowry definition states that an acid is a proton donor.
Click to flip
What is a conjugate base?
Click to flip
A conjugate base is the species formed when an acid donates a proton.
Click to flip
What is an amphoteric substance?
Click to flip
An amphoteric substance can act as both an acid and a base.
Click to flip
Give an example of an amphoteric substance.
Click to flip
Water (H2O) is an example of an amphoteric substance.
Click to flip
What is the concept of pKa?
Click to flip
The pKa is a measure of the strength of an acid; lower pKa values indicate stronger acids.
Click to flip
What is the relationship between acids and conjugate bases?
Click to flip
Stronger acids have weaker conjugate bases, and weaker acids have stronger conjugate bases.
Click to flip
How do acids behave in a Bronsted-Lowry reaction?
Click to flip
In a Bronsted-Lowry reaction, acids donate protons to bases.
Click to flip
What is the role of acids in a buffer solution?
Click to flip
Acids in buffers can help neutralize added bases, helping to maintain pH levels.
Click to flip
How are acid dissociation constants expressed?
Click to flip
Acid dissociation constants are expressed as Ka values.
Click to flip
What is a Lewis acid?
Click to flip
A Lewis acid is a substance that can accept an electron pair.
Click to flip
What distinguishes strong acids from weak acids?
Click to flip
Strong acids completely dissociate in solution, while weak acids do not.
Click to flip
What is an example of a weak acid?
Click to flip
Acetic acid (CH3COOH) is an example of a weak acid.
Click to flip
What is hydrolysis in the context of acids and bases?
Click to flip
Hydrolysis involves the reaction of an ion with water to form an acid or a base.
Click to flip
How do acids contribute to redox reactions?
Click to flip
Acids can donate protons to facilitate oxidation-reduction (redox) reactions.
Click to flip
What is a practical application of understanding acid-base chemistry?
Click to flip
Understanding acid-base chemistry is crucial in industries like pharmaceuticals, food preservation, and environmental science.
