S block
group 1,2 metals
Reaction with water
Group I metal for hydroxide and hydrogen
gas
metal dissolves
melts into a silvery ball
moves quickly on the watersurface
hissing sound heard
gas bubbles evolve
heat is produced
eg 2Na 21120 2NaOH Hs
Group 2 metals
Similar reaction but less vigorously
e g Cat21120 Ca OH at Hs
Note reactivity increases down a
group
, Reaction with acid
Group't metal too reactive
x
Group 2 metal hydrochloric acid
give bubbles of hydrogen
es srtatattsici.it
sulphuric acid
only manesium reacts others have insolublesulphate
I depend on solubility table
Group I metals and NHat all compoundsoluble inwater
all nitrates Noi all compound soluble in water
hydrogencarbonates H005 all METAL hydrogencarbonates solubl
Carbonates
cot all insolubleexcept group I and NHat
Hydroxides OH allinsoluble except for group andNHat
Group 2 MsHI insoluble but solubilityincreasesdownthegroup
i Bacon soluble
Sulphate 5042 all soluble exceptsome group2
