A homogenised cell solution is centrifuged at 15000g for 15 minutes. Could you name one organelle present in the supernatant and in the pellet

Devise a sequence of reactions to follow (using filtering or centrifuging where necessary to remove precipitates) to identify an unknown solution containing all of the following ions: Chlorine (Cl), Hydroxide (OH), Sulphur (S2-), Sulphate (SO43-)

Ack, I completely missed the questions during a lab that I did just to learn procedure. It was the first day, I was a little lost haha. But all we did was cut DNA with restriction enzymes – one of the questions that I didn’t do asks “before you incubated your samples, describe any visible [...]

Using a laboratory centrifuge?

Tags: Gravity, Separated, Separation, Solution, With

A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off it continues to rotate with a constant angular deceleration for 16 s [...]

Actually if the system is a true solution you cannot separate a solute from the solution with a centrifuge. The dissolved particles are either ions or molecules which cannot be removed even by filtration. You can remove the solvent from a dissolved solid (the solute) by evaporation or simple distillation. An example of this would [...]
