2
Q
define acid
A
an acid is a species that releases H+ ions in aqueous solutions
3
Q
define salt
A
salts are produced from reactions of acids and contain positive and negative ions
4
Q
Metal + acid ->
A
Metal + acid -> salt + hydrogen
if the metal is more reactive than hydrogen it will react and displace BUT if not there will be no reaction
5
