Acids, Bases And Neutralisation Flashcards
What do all acids contain in their formulae?
Hydrogen ions.
What happens when an acid is dissolved in water?
Hydrogen ions are released in solution.
What does a strong acid do in water?
It releases all of its hydrogen ions which is known as complete dissociation.
What is a good example of a strong acid?
HCl
What does a weak acid do when dissolved in water?
It only releases a small proportion of hydrogen ions into the solution (partial dissociation).
What type of acid tends to be weak?
Organic acid.
Give an example of a weak acid.
Ethanoic acid.
What are the different types of base?
Metal oxides
Metal hydroxides
Metal carbonates
Ammonia
What is the molecular formula of ammonia?
NH3
What does a base do to an acid?
It neutralises an acid to form a salt.
What is an alkali?
This is a base that dissolves in water releasing hydroxide ions into a solution.
What are the three metal oxide bases?
MgO
CaO
CuO
What are the common metal carbonate bases?
Na2CO3
CaCO3
CuCO3
What are the three common alkali bases?
NaOH
KOH
NH3
What part of the acid reacts with the base in neutralisation?
The hydrogen ions.
