Acids, bases and salts

?
What are the state symbols in equations?
(s), (l), (g) and (aq)
1 of 12
Soluble salts can be made from acids by reacting them with one of what 3 things?
Metals, insoluble bases or alkalis.
2 of 12
How are solid salts produced from salt solutions?
Crystallisation.
3 of 12
How are insoluble salts made?
By mixing appropriate solutions of ions so that a precipitate is formed.
4 of 12
What is precipitation used for?
To remove unwanted ions from solutions.
5 of 12
Metal oxides and hyrdoxides are called what?
Bases
6 of 12
Soluble hydroxides are called what?
Alkalis.
7 of 12
The particular salt produced in any reaction between an acid and a base or alkali depends on what 2 things?
The acid used (hydrochloric acid produces chlorides, nitric acid produces nitrates, sulfuric acid produces sulfates) and the metal in the base or alkali.
8 of 12
Ammonia dissolves in water to produce what kind of a solution? What does this produce?
Alkaline. Ammonium salts (important in fertilisers).
9 of 12
Hydrogen ions, H+(aq), make solutions what?
Acidic
10 of 12
Hydrogen ions, OH-(aq), make solutions what?
Alkaline
11 of 12
In neutralisation reactions, what 2 ions react together and what do they produce? Give the chemical equation.
Hydrogen ions react with hydroxide ions to produce water. H+(aq) + OH-(aq) = H20(l)
