Aim :

To investigation the reaction of halogens withiron

Aim :

To investigate the effect of concentration of ionson the selective discharge of ion at the electrodes of aqueous hydrochloric acid.

Aim :

To investigate the effect of the types of electrodeson the products of electrolysis of aqueous copper(II)sulphate solution.

Problem statement :How does reactivity of halogens change when they reactwith iron?Problem statement :How does the concentration of ions in hydrochloric acidaffect the discharge of ions at the anode?Problem statement :How does the type of products formed during theelectrolysis?VariableManipulated :Responding :Controlled :VariableManipulated :Responding :Controlled :VariableManipulated :Responding :Controlled :Hypothesis :The reactivity of halogens decreases downthe group from chlorine to bromine when they react withiron.Hypothesis : When the concentration of chloride ion ishigher, then the chloride ion will be preferentiallydischarge.Hypothesis : When copper electrodes are used instead of carbon electrodes, the types of products formed at theanode are different.Materials: Materials: Materials:Apparatus : Apparatus : Apparatus :Procedure : Procedure : Procedure :Tabulation data : Tabulation data : Tabulation data :
