1.5 Acids And Bases Flashcards
What does acid and a metal react together to make?
A salt and hydrogen
-acid + metal Oxide —> A salt + hydrogen.
What does an acid and a metal oxide/hydroxide react together to make?
A salt and water
- acid + metal oxide/hydroxide —> a salt + water.
What does an acid and a carbonate react together to make?
A salt and water and Carbon dioxide
-acid + carbonate —>a salt + carbon dioxide + water.
What is the chemical and ionic formula of hydrochloride acid?

Na+ OH-
What is the chemical and ionic formula of barium hydroxide?
BaOH
Ba^2+ (OH)_2
What is the chemical and ionic formula of lithium hydroxide?

Soluble metal oxides (bases) produce…
Alkalis
A neutralisation reaction produces…
A salt + water.
Spectator ions are ions that are…
Present during the reaction but remain unchanged after.
All acids contain ions and as a result…
Conduct electricity.
Because the ions are free to carry the charge
Soluble non-metal oxides produce….
Acids
Alkalis contain ions and as a result…
Conduct electricity.
Because the electrons are free to carry the charge
Acids and alkalis are formed….
By dissolving different oxides in water.
When an acid is diluted the water concentration of H+ ions is….
Decreased.
So the pH moves towards 7.
Alkalis solutions have a higher concentration of….
OH- (hydroxide ions.)
Acidic solutions have a higher concentration of…
H+ (hydrogen ions.)
