Acids, Alkalis And Salts Flashcards
How are solid salts produced?
Salt solutions being crystallised.
How can insoluble salts be made?
By mixing appropriate solutions of ions so that a precipitate is formed.
What can precipitation be used for?
To remove unwanted ions from solutions.
Give an example of a base and alkali.
Base - Metal oxide and hydroxide
Alkali - Soluble hydroxide
What does the particular salt produced in any reaction between an acid/base/alkali depend on?
The acid used.
The metal in the base or alkali.
How can soluble salts be made from acids?
By reacting them with metals, insoluble bases and alkalis.
What does ammonia dissolved in water produce? What is it used for/important for?
It produces an alkaline solution.
Used to form ammonium salts.
Important as fertilisers.
What do hydrogen/hydroxide ions make?
Hydrogen ions make solutions acidic.
Hydroxide ions make solutions alkaline.
What is the ph scale?
The measure of acidity or alkalinity of a solution.
What happens in neutralisation reactions?
Hydrogen ions react with hydroxide ions to produce water.
