GROUP 2A + H2O
Group 2A +
H2O
M = Be,Mg,Ca,Ba
Ø Be has no reaction with water
Ø Mg reacts with boiling water
Ø Calcium to barium react with
water at 25oC with increasing rapidity
water at 25oC with increasing rapidity
M + 2H2O ® M(OH)2 + H2
again an increasing rapidity to
react as we move down the Group.
• Be does not react as it has low
reactivity & forms covalent rather than ionic bonds.
