The only real requirement is that the water must not be alkaline, otherwise the carbon dioxide would react with it, and be absorbed. The gas isn't very soluble at all in distilled water, and can therefore be collected over it.

For the normal preparation of carbon dioxide ordinary tap water is perfectly adequate. If you wanted a little more you could collect the gas over soda water (carbonated water) as that is saturated with carbon dioxide none of the collected gas would be lost by it dissolving but it is almost like 'cheating'. The water is displaced DOWNWARDS by the way.

it doesnt have to be distilled. the gas upwardly displaces the water to be collected.
any liquid would give similar results.
