Acids and Alkalis - Strong and Weak Acids Flashcards
1
Q
What is an acid?
A
Acids are substances that form hydrogen (H+) ions when they dissolve in water (aqueous solutions).
2
Q
What is an alkali?
A
Alkalis are substances that form hydroxide (OH-) ions when they dissolve in water (aqueous solutions).
3
Q
What is a strong acid?
A
Strong acids fully ionise in water, meaning that all of the acid molecules break up to form H+ ions
4
Q
What is a weak acid?
A
Only partially ionise in water, meaning that not all of the acid molecules break up up to form H+ ions.
