What is disproportionation?
The halogens are under disproportionation when they react with...
Give the general symbol equation for the reaction between a halogen and dilute sodium hydroxide
Give the general ionic equation for the reaction between a halogen and dilute sodium hydroxide
TRUE OR FALSE:
All of the halogens can exist in oxidation states other than 0 and -1
Give the name and oxidation number of chlorine in ClO⁻
What is the common use of sodium chlorate (I) solution?
How is bleach made? Give the balanced symbol equation for the reaction
In the reaction between sodium hydroxide and chlorine gas to form bleach, which element undergoes disproportionation?
When you mix chlorine with water, it undergoes disproportionation. The products are hydrochloric acid and chloric (I) acid (also known as hypochlorous acid). Give the balanced symbol equation for this reaction
Chloric (I) acid is formed when chlorine is mixed with water. Aqueous chloric (I) acid ionises to make chlorate (I) ions (also called hypochlorite ions). Give the balanced symbol equation for the ionisation of chloric (I) acid
What is the use of chlorine (or a compound containing chlorate (I) ions)?
What are the risks of using chlorine to treat water?
Why might people object to having their water chlorinated in terms of ethical considerations?
What are the two alternatives to chlorine in water treatment?
How might ozone be used for water treatment?
What are the disadvantages of using ozone for water treatment?
How might UV be used for water treatment?
What are the disadvantages of using UV for water treatment?
