Strong and Weak Acids Flashcards
1
Q
Explain what is meant by a ‘strong acid’.
A
An acid that fully dissociates in water to form H⁺ ions
2
Q
Explain what is meant by a ‘weak acid’.
A
An acid that only partially dissociates in water, meaning it forms few H⁺ ions
3
Q
Explain what is meant by a ‘concentrated acid’.
A
An acid that has a large number of acid molecules compared to the volume of water
4
Q
Explain what is meant by a ‘dilute acid’.
A
An acid that has a small number of acid molecules compared to the volume of water
