What are the common properties of acids?

(6)
They are Covalent Molecular
Taste Sour
Are Corrosive
Turn blue litmus red
when dissolved in water they IONISE
are neutralised by bases
A reaction of an acid and metal will produce..?
Salt and hydrogen gas
A reaction of an acid and base (metal hydroxide) will produce..?
Salt and water
A reaction of an acid and metal carbonate will produce..?
Salt, carbon dioxide and water
A reaction of an acid and metal hydrogen carbonate will produce..?
Salt, carbon dioxide and water
A reaction of an acid and metal oxide will produce..?
Salt and water
What are the common properties of bases?

(6)
Most bases are IONIC yet some are MOLECULAR COVALENT
Taste Bitter
Feel slippery
May be corrosive
Turn red litmus blue
when dissolved covalent molecular bases ionise, and ionic bases dissociate
STRONG ACIDS readily donate their proton and thereby...
completely ionise!
examples of some strong acids are..
Hydrochloric acid, sulfuric acid and nitric acid
Weak acids only partially ionise. An example of aweak acids is..
Ethanoic acid (acetic acid)
WHICH STRENGTH OF BASE completely dissociates in water, breaking apart into positive and negative ions, then in the case of an oxide ion, completely reacts with water by accepting a proton to form the hydroxide ion.
STRONG bases.
Weak bases like ammonia only ____________ ionise in water
Weak bases like ammonia only partially ionise in water
