Separating Mixtures: Lab Experiments & Methods

[osirisgeek]

Greetings,
I have just done a lab in which we separated NaCl, NH4Cl, and SiO2.

To separate first the mixture was heated and the Nh4Cl sublimed (in which i measured teh content by mass loss)

Then I extracted the NaCl using soluability by adding water then evaporating the water leaving the Table salt to be weighed.

Last the wet Sio2 was left and it was just heated to get a constant mass.

Im trying to figure out if its possible to separate this in a differnt order, or will it not work properly. I am thinkings its not possible because you must first separate the solid and the liquid to properly measure the solids weight.

Does this seem right?

by different order are you referring to, perhaps, dissolving the solid mixture in water first?

Hello,

Thank you for sharing your lab experiment with me. Your method of separating the mixture of NaCl, NH4Cl, and SiO2 seems to be effective and efficient. It is important to separate the solid and liquid components first in order to accurately measure the weight of the solids. Changing the order of separation may not work as effectively and could lead to inaccurate measurements. However, there may be other methods of separation that could be explored. I suggest researching and experimenting with different techniques to see if you can achieve similar results. Keep up the good work!
