Is there a mistake in Heinemann?

On page. 457-458 in the heinemann yr 12 chem book the book says that the an electrolyte of NaCl will, at the anode, have on oxidation reaction of chlorine. But isn't this supposed to be water.
I'm really confused and have spent ages on this.

Please help.

remember that the ECS was developed under standard conditions (25C, 1atm, 1M)

read the paragraph at the top of pg 458 and it explains that by modifying the conditions slightly (such as a high concentration of NaCl) can cause the chloride ions to undergo oxidation rather than the water. Seeing as Cl2 gas is what they want to produce, they would modify the conditions of their electrolytic cell to ensure that this is the reaction that occurred.
