How do you prepare saturated solution?

Answer 1

It's easy! No measurement is necessary. Just keep adding solute and stirring until you have a visible surplus of solute crystals that won't dissolve. For example, a stock of saturated NaCl solution will always have undissolved salt crystals on the bottom of the container.

Answer 2

To make saturated salt solution it will require 30-35 gm of salt in 100 gm of water at room temperature say 37C. Heating of the salt solution doesn't increase the solubility significantly as happens in the case of sugar. However how long a saturated salt solution can last bacteria free is not clear. Halo bacteria are known to survive in saturated salt solutions as in dead seas.

Answer 3

First think about the question. This is important.

The question is REALLY asking you this:

"How do you dissolve something in water without heating it"

So think up your Koolaid answer. When you make Koolaid you don't want warm or hot koolaid, you want nice cold Koolaid that you can drink right away.

So what do you do. You take out your packet of koolaid and dump it into a container and fill it with some water.

Now what do you do? Just let it sit and hope it all gets stirred up by itself? No, you stir it until its all dissolved.

The second part of the questions mentions Saturated. This usually means completely soaking wet, but in chemistry it means the water is so full of koolaid that no more can be dissolved.

So to make really really bad Koolaid, you take a glass of water that's not cold, stir in a whole bunch of koolaid and keep stirring and adding in more until no more koolaid can be dissolved. Then it would be saturated at room temperature

Answer 4

A solution is saturated when it has the maximum amount of solute. If you tried to add one more particle of solute, it would not dissolve. So, to make a saturated solution you simply add more solute until the solvent will not hold any more.

Answer 5

You would put your desired solute in your desired solvent until no more will dissolve, and then add some excess in, so that you can see some in the bottom of the solvent. You would then heat it until the excess has dissolved, at which point you have your supersaturated solution!

Answer 6

Heat it up... for instance water and sugar

Answer 7

we add solute in the solvent for that time when the solvent can not dissolve at any more

Answer 8

By adding the solute over the limit of solubility at a given temperature.
