does Alka seltzer tablets dissolve faster in room temperature water or in cold water ?

Answer 1

Heat speeds us chemical reactions in general, including dissolution.
Also the solubiliuty of a gas in a liquid is affexted by the temperature of the liquid. As the temperature of the liquid increases, the amount of carbon dioxide, or any gas that can remain in the solution decreases.

Answer 2

It's funny you asked this question, because I can't stand the taste of Alka Seltzer, I like it in ice cold water. So that's how I come to know that it seems to disolve at about the same amount of time as it does with water straight out of the tap. And, since I've also used a Brita water filter, I've also done it with room temperature water, and it seemed to take about the same amount of time. Now these weren't scientific measurements I'd taken, but I do know this as I'm a curious type. Alka Seltzer definately disolves much faster in boiling water, vinegar, and battery acid, although the latter two can make a big mess and hurt you if you aren't careful....

Answer 3

in spite of if this test is virtually too easy to work out the three variable varieties: Water Temperature = self reliant variable Time to dissolve = based variable Alka Seltzer pill length = administration The water temperature is replaced with a view to observe a metamorphosis interior the time to dissolve, which relies upon on the temperature of the water. the size of the Alka Seltzer pill is the only element in this test which could be controlled, yet isn't replaced.

Answer 4

I've tried this before, and they definitely dissolve faster in water that is room temperature. I think the cold water slows down the break-down of the tablet.

Answer 5

It will dissolve faster in room temperature than in cold water. The gas being bubbled is carbon dioxide which has a greater solubility in cold water than in tepid water, as most gases are.

Another way to observe this is when you let Coca-Cola or Pepsi stand in the open at ice cold temp versus very warm temperature. You will notice more bubbling in the warm than in the ice cold one.

Answer 6

warmer water means more thermal energy is available to accelerate the reaction - so if by cold water you mean colder than the ambient (room) temperature, then the reaction (dissolution of the tablet) will occur more rapidly at room temperature.

Answer 7

Room temperature, but then isn't whatever the temp of a room is, isn't that room temperature. Say if it's 70 degrees in that room, isn't 70 degrees room temperature? Or 40 degrees......
