Acids And Salts Flashcards
Definition of a base
Proton acceptor
Definition of an alkali
A base that dissolves in water and releases hydroxyl ions (OH-)
Why is ammonia a base?
Because it accepts a proton from water
Metal + acid =
Salt + hydrogen
Metal oxide + acid=
Salt + water
Base + acid
Salt + water
Metal carbonate + acid=
Salt + water + carbon dioxide
What’s a strong acid?
An acid that fully dissociates in water
What ion forms when the hydrogen ions form a dative bond with water?
Oxonium ion (H3O+)
What’s a weak acid?
An acid that partially dissociates in water
What’s a spectator ion?
The state or charge of the ion remains the same throughout the reaction
What’s a salt?
When the hydrogen ion of an acid is replaced by a metal ion or ammonium
What’s a hydrated salt?
A salt that contains metal ions, counter ions and water of crystallisation
Definition of an acid
When dissolved in water they release hydrogen ions (H+) so are called proton donors
