Barium sulfate is used to make the digestive tract visible in X-rays. For it to be visible, it must remain insoluble. A pharmacist preparing a slurry of barium sulfate should choose to dissolve the barium sulfate in

Hope the image of the frequency formula

The velocity would be 2 

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
