Acids, Bases And Salts Flashcards
Soluble salts can be made from acids by reacting them with..
Metals
Insoluble bases
Alkalis
What are the state symbols in equations
(s) (I) (g) (aq)
What is the problem with reacting acids with metals
Not all metals are suitable,
Some are too reactive and others are not reactive enough
What happens with insoluble bases and acids reacting
The base is added to the acid until no more will react and the excess solid is filtered off
What happens with alkalis and acids reacting
An indicator can be used to show when the acid and alkali have completely reaction to produce a salt solution
How can salt solutions be used to produce solid salts
They can be crystallised
How can insoluble salts be made
By mixing appropriate solutions of ions so that a precipitate is formed
What can precipitation be used to remove
Unwanted ions from solutions,
E.g. In treating water for drinking or in treating effluent
What are metal oxides and hydroxides
Bases
What are soluble hydroxides
Alkalis
the particular salt produced in any reaction between an acid and a base depends on what…
- the acid used
- the metal in the base or alkali
What does ammonia dissolve in water to produce?
Alkaline solution
What is alkaline solution used to produce
Ammonium salts
What are ammonium salts important as
Fertilisers
What do Hydrogen ions make solutions
Acidic
