What happens when an acid reacts with a metal carbonate?
When an acid reacts with a metal carbonate, salt, water and carbon dioxide is formed. This is neutralisation.
What is a strong acid?
An acid that will fully dissociate (ionise) in water with a low pH scale (1-2)
What is a weak acid?
An acid that will partially dissociate (ionise) in water, with a pH of 3-6.
What happens to the volume in a concentrated acid?
A lot of acid particles in a given volume
What happens to the volume in a dilute acid?
not many acid particles in a given volume.
What happens if a metal and an acid react?
A salt and hydrogen will be formed
What happens if a metal hydroxide reacts with an acid?
A salt and water will be formed.
What happens if a metal oxide reacts with an acid?
A salt and water will be formed.
What happens if a metal carbonate reacts with an acid?
A salt, water and carbon dioxide will be formed.
What happens if ammonia reacts with an acid?
An ammonium acid will form.
How to name a salt?
The first part is the metal, metal oxide or metal carbonate, the second part is from the acid. e.g. Fe + HCl = FeCl + H2
What is the formula of Hydrochloric acid?
HCl
What is the formula of Sulfur acid?
H2SO4
