Acids And Alkalis Flashcards
Properties of metal oxides?
Solids at room temperature.
Are bases.
Properties of non-metal oxides?
Usually gases at room temp.
When dissolved form an acidic solution.
What is oxidation?
When something gains oxygen, the loss of electrons.
What is reduction?
When something loses oxygen, the gain of electrons.
What is an ore?
A material from which a metal/ valuable mineral can be profitably extracted.
How do you write a balanced half equation?
Electrons are shown as e^-
The numbers of atoms for each element must be the same on each side.
The total charge is 0
What is an acid?
A substance that donated hydrogen ions in aqueous solutions. (H^+)
What is an alkali?
A substance that makes hydroxide ions in aqueous solutions (OH^-)
What makes an acid strong?
Its ability to donate more protons.
What makes an acid weak?
The fact that it does not donate as many protons.
What do neutralisation reactions occur between?
Acids and alkalis.
