Acids and Bases Flashcards
1
Q
What is an acid?
A
An acid is a substance which produces hydrogen ions when it is dissolved in water.
2
Q
What is the ion responsible for its acidic property?
A
H+ (hydrogen ions)
3
Q
What is the strength of acid?
A
The strength of an acid depends on the degree of ionisation when dissolved in water.
4
Q
Why do strong acids have high concentrations of hydrogen ions?
A
Strong acids dissociate completely in water, thus more hydrogen ions are produced.
5
Q
What is the difference between the degree of ionisation of strong and weak acid?
A
Strong acids ionise completely in water whereas weak acids ionise partially in water. Thus, strong acids have a higher degree of ionisation than weak acids.
