General properties of acids
Acids turn blue litmus paper red
Acids has a pH value less than 7
Acids have a sour taste
Acids are corrosive
Acids can conduct electricity
Acids react with metals, carbonates and bases/alkalis
Bases
The base is bitter in taste and soapy feeling
A substance used to neutralise acid is called a base.
Base reacts with acids in order to make it neutral
They produce salt molecules and water on reacting with acids.
Bases do not dissolve in water.
They are corrosive
Turn red litmus paper blue
They can conduct electricity
Can't dissolve in water
Chemical reactions with acids
Acid+metal = salt+hydrogen
acid+carbonate=salt+water+carbon dioxide
acid+base/alkali=salt+water
Alkali
Alkali is a base.
Not all bases are alkali but all alkali is base.
On adding acid to alkali the pH decreases due to the removal of alkali.
Neutralisation is a reaction in which removal of alkalinity or acidity occurs.
On adding alkali to acid the pH of the mixture increase.
Bases which are soluble in water
