The 2 ions that make up the ionic compound are disociated in water. This means that they are free to move about on their own. So each one goes to the oppositely charged electrode, splitting the ionic compound into it's 2 ions.
This means that at one electrode there is a gas formed and at the other electrode there is a group 1 metal formed. In your write up can you write a word equation that describes what has just happened? Then write a balanced symbol equation to describe the breakdown of salt including the charges on each ion.
Now look at the safety points.
Ýou have been told that you may smell a gas produced that smells like swimming pools. What is this gas? Which electrode does it form at the anode or the cathode? Remember that it goes to the opposite pole.
At the other electrode there is group I metal formed. Now think about the properties of group I metals. You were warned that the solution produced would be dangerous and you needed to wear goggles. Why do you think this is?
The group I metal is created in water. What happens when group I reacts with water? What happens to the water? What other gas is produced? Write a word and balanced symbol equation in your write up to explain the second reaction in the experiment. Full marks will only go to those who have related all the theory to the practical.

post ur really name... and in response i didn't make a fool of my self, and my notes were good as mr hoang said but i didn't have the TIME or RESPECT todo my lesson. and tell me which part did i make a fool of myself in? was it the part where i wnted to smash each of ur heads or was it the part when i was tieng to get a msg ove but u students just shut it out bcs u were too arrogant to learn fom a fellow student? why wouldn't u do thisto mr owen for an example. its because he is bigger. but since i'm the same age, or actually second smallest person in the class (after Abbas) u just shut me out and locked me away. if u let me finish i had lined up another whole 2 pages of writing and exmples but nooooooooo Imitates silly con "i'm too stuck up to learn from a fellow student" uits nice to get to know the really ppl behind the masks. all the ppl who r like 'hi' and 'bye' and 'where r u going' and 'wanna come with us' its realy nice to know the real faces 0_______________o ~~ potassium
oh ya. mr hoang will re explain the lesson u arrogant stuck up sill girl/guy/fatmah
heya..with all due respect sir..3 peices of h/w?:S
c'mon!
heya..with all due respect sir..3 pieces of h/w?:S
c'mon!
LOOOOL,,whoever created the other web..KUDOS to u mate;)
and the experiment as easy..
