Salts

?
What is a salt?
A salt is a word used to describe many different ionic compounds
1 of 16
How are soluble salts formed?
By reacting an acid with either a metal, insoluble base or alkali
2 of 16
Name a vigorous reaction between a metal and an acid? What are the products?
Potassium + Hydrochloric Acid = Potassium Chloride + Hydrogen
3 of 16
What are bases?
Bases are the oxides and hydroxides of metals.
4 of 16
What are soluble bases?
Soluble bases are called alkalis
5 of 16
Why is preparing salts for transition metals less straightforward?
Their oxides and hydroxides are insoluble
6 of 16
What is the general equation for the reaction of an acid and a base?
Acid + Base = Salt + Water
7 of 16
What is the general equation for an acid and an alkali?
Acid + Alkali = Salt + Water
8 of 16
In an acid/alkali reaction - what use do indicators have?
They show when the reaction is complete.
9 of 16
How can precipitation of insoluble salts be useful?
For removing unwanted ions from drinking water.
10 of 16
What is precipitation of insoluble salts?
When a solid substance is formed from insoluble ions.
11 of 16
What happens to acids and alkalis in water?
They dissociate to produce H+ (acid) ions or OH- ions in solution.
12 of 16
What are the products of: Acid + Alkaline Hydroxide Solution?
A neutral salt + water
13 of 16
Give an example of a neutralisation reaction
Hydrochloric Acid + Potassium Hydroxide = Potassium Chloride + Water

Why is ammonia useful?
It is used in agriculture to create fertilisers.

When are nitrates an issue?
When they enter rivers and streams and contaminate drinking water.
