Module 3- Reactions Of Chlroine Flashcards
1
Q
What is the reaction for cleaning water (water+ chlorine)?
A
Cl2 + H2O -> HCl + HClO
2
Q
Why is the reaction of water and chlorine a disproportionation reaction??
A
The Chlorine has an oxidation state of 0 as Cl2, and the becomes -1 in HCl and +1 in HClO. The chlorine is reduced and oxidised
3
Q
How does the reaction of water and Chlorine clean the water??
A
The bacteria are killed by ClO- ions
4
Q
What is the formula for the reaction between Cl2 gas and aqueous NaOH
A
Cl2 + 2NaOH -> NaCl + NaCLO + H2O
5
Q
What are the risks of cleaning water with chlorine??
A
Any hydrocarbons in the water can react with the Chlorine to form haloalkanes that can cause cancer
