Group 1 Reactions Flashcards
What is the general equation with grp1 elements with oxygen
4M (s) + O2 (g) —> 2M2O (s)
What colour are group 1 oxides
White solids
What are Li, Na and K stored in
Oil
Why are Li, Na and K stored in oil
Because they aren’t highly reactive with oxygen and so storing the in oil with prevent them from reactions with the oxygen in the atmosphere
Where are Rb and Cs stored
In tubes of inert gases
why are Rb and Cs stored in tubes of inert gases
To prevent contact with oxygen in the air
What is the general formula with grp1 metals and chlorine
2M (s) + Cl2 (g) —> 2MCl2 (s)
What’s the colour of the group 1 chlorides
All white solids
Are group 1 chlorides soluble or insoluble in water
Soluble in water
What is the general formula with grp1 metals and water
2M(s) + 2H2O (l) —> 2MOH (g) + H2 (g)
What type of water do group 1 metals react with
Cold water
What is seen when group 1 metals are reacted with water
Fizzing, metal dissolving, UI turns blue purple
What happens to the temp of the solution when grp1 metals react with water
Temp increases
What happens to the colour of the UI solution when group 1 metals react with water
Turns blue / purple
