You have a sugar solution that is saturated and in equilibrium with a solid sugar cube (sugar cube A). You then add a second sugar cube (sugar cube B) containing radioactive sugar. After letting the solution sit overnight, you observe the next day that both sugar cubes are the same size they were the previous day. Where do you expect the radioactive sugar to be found, explain why?

A saturated solution of a solid dissolved in a liquid will typically have some solid visible on the bottom of the container. Which of the following is true? Explain your reasoning. 1. The visible solid particles are constant, made up of the same particles of solid at some later point in time as they were at an earlier point of time since the saturated solution was formed. 2. The visible solid particles are constantly being dissolved into solution and reformed....

Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...

Situation 1: You have a metal cube, measuring L on each side. The metal is in electrostatic equilibrium and has a net 4. charge of Q,. The cube has a cavity within it, however-where there is no metal. The shape of this cavity is not known. Somewhere within the cavity rests a point charge, q,. Its exact location is unknown, but it is not in contact with the inner wall of the cavity At a certain point P, on the...
