Chlorine is a halogen that undergoes a disproportionation reaction in cold, alkaline conditions.
When chlorine gas is reacted with cold, dilute sodium hydroxide solution, it forms sodium chloride solution, sodium chlorate(I) (NaClO\text{NaClO}NaClO), and water.
Complete the balanced equation for this reaction, including the three missing chemical formulae and their corresponding state symbols.
