Suppose u place a beaker containing a solution in a refrigerator , an hr later a white solid is found on thr bottom of thr beaker. What happened. Why?
I think a precipitate formed, but can any1 explain briefly so i can understand better? Thanks
Some solute was dissolved in the water and it was soluble at room temperature. When you placed the beaker in the water the temperature decreased, the solubility of the solute is less at cooler temperatures; therefore, some of it precipitated(came out of)(crystallized) etc. from solution.
Yes, you are correct! It sounds like a precipitate formed in the beaker. A precipitate is a solid substance that forms when two or more substances in a solution react chemically with each other.
In this case, when the beaker with the solution was placed in the refrigerator, the temperature dropped. Lowering the temperature can cause the solubility of certain substances in the solution to decrease. Solubility refers to the ability of a substance to dissolve in a solvent.
When the solubility decreases, it means that the substance becomes less capable of remaining dissolved in the solution. This can result in the formation of solid particles, known as a precipitate. The precipitate settles at the bottom of the beaker because it is more dense than the liquid in which it formed.
The exact reaction that led to the formation of the precipitate would depend on the specific substances present in the solution. Chemical reactions that commonly result in the formation of a precipitate include the combination of two solutions that contain ions that can react with each other to produce an insoluble compound.
It's important to note that the formation of a precipitate when the solution is cooled is not always guaranteed. It depends on the specific composition of the solution and the conditions under which it is being cooled.
