What is displacement?
The action of moving something from its place or position.
What is oxidation?
The loss of electrons.
What is reduction?
The gain of electrons.
What is a neutralisation reaction?
A reaction of an acid with a base.
Are all bases soluble?
No. Only alkalis are soluble.

Salt + Hydrogen
What is a redux reaction?
A reaction of an acid with an alkali.
What are the products of: Acid + Metal Oxide?
Salt + Water
What are the products of: Acid + Metal Hydroxide?
Salt + Water
H+ plus OH - equals?
H2O, also known as water.
How are aqueous H+ ions made?
When acidic compounds dissolve in water.
When the pH increases by 1, by how much does the amount of H+ ions decrease?
It decreases by 10.
Are these enough flashcards?
Hopefully.
