Expert Answer
Dear Student,
Bases are chemical substances with a bitter taste and are soapy to touch.
The term ‘Bases’ are oxides or hydroxides of metals which react with acids to give salt and water.
Examples:
Oxides of metals: CuO, MgO, PbO
Hydroxides of metals: Fe(OH)2, Pb(OH)2, Al(OH)2
Alkali : The term ‘Alkalis’ are bases which are soluble in water.
All alkalis are bases, but all bases are not alkalis.
This is because certain bases are insoluble in water.
Examples:
Oxides of metals: K2O, Na2O
Hydroxides of metals: NaOH, KOH, NH4OH
