The following statements apply to the reaction between arsenic
(V) and iodide ions.
Reaction to be carried out: AsO43- + 2I- + 2H+=
AsO33- + I2 + H2O
Eo arsenic acid / arsenic acid = +0.56 V; Eo I2 / 2I- = +0.54 V;
Which statements are true?
1, Based on standard redox potentials, iodine is the oxidizing
agent.
2, Sodium bicarbonate solution added to the reaction mixture
shifts the equilibrium towards the formation of starting
materials.
3, The iodine formed in the reaction precipitates and shifts the
reaction towards formation.
4, Hydrochloric acid solution added to the reaction mixture
shifts the equilibrium towards the formation of reaction
products.
