Liquids. I seem to recall from college chem courses that chemical activity roughly doubles with each 10 C rise in temperature. This would suggest that each comparable drop in temp would halve deterioration, although enough drop might precipitate components which might then be difficult to redisolve. So, with the proper temperature for a fridge being perhaps 35 F what will precipitate out, and can it be re-dissolved? Any experience out there? I know that some formulae for developers specify the temperature of the solute and the order of addition of components; this suggests that cooling below STP might be deleterious.... Any photo chemists out there who might weigh in?
