I was wondering how does one make a saturated chemical solution?
I'm supposed to make one, is there a way I can determine the ammount solute needed for a certain amount of solvent?
If not, how do I make a saturated solution?
Thank you
Generally, saturated solutions (at a given temp) are made by putting an excess into the solvent, and ensuring that the mixing (shaking or stirring) is well done. The saturated solution then is taken off the excess in the bottom of the decanter. Now a caution here: varying temperature changes the saturation point.
It was not stated, so I assume that I will be making them at std room temp.
Thanks for the help, bobpursley.
To make a saturated chemical solution, you need to dissolve as much solute as possible in a given amount of solvent. The saturation point is reached when the solvent can no longer dissolve any more solute at a given temperature.
To determine the amount of solute needed for a certain amount of solvent, you can use a solubility chart or look up the solubility of the specific chemical in a reference book or online database. The solubility is given in units of mass of solute per volume of solvent (e.g., grams per liter).
Here's the step-by-step process to make a saturated solution:
1. Determine the desired amount of solvent: Decide how much solvent (e.g., water) you want to use for your solution. This could be measured in liters, milliliters, or any other suitable unit of volume.
2. Check the solubility: Look up the solubility of the solute in the chosen solvent at the desired temperature. Make sure the solubility value is given in the same units as your chosen solvent volume.
3. Weigh the solute: Calculate the mass of solute needed using the solubility information. Multiply the solubility (in g/L) by the volume of solvent (in liters). This will give you the mass of solute required to saturate the solution.
4. Dissolve the solute: Measure out the calculated mass of solute using a balance or scale, transfer it into the solvent, and mix thoroughly. Start by adding less than the calculated amount and gradually add more while stirring until no more solute dissolves.
5. Observe saturation: If the solution is fully saturated, you will notice that there is undissolved solute settled at the bottom of the container. If the solute completely dissolves, the solution is either not saturated or the solubility value used was incorrect.
Remember that solubility is temperature-dependent, so it's crucial to consider the temperature for accurate results.
