How would Rf values changes of Cations if the developing chamber left uncovered in paper Chromatography?
The solvent would keep on evaporating from the chromatogram and as a result it would keep on bringing the cations up, causing an increase in the Rf value.
What is a conclusion for candy chromatography?
Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography, a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action, the. components of the sample are carried along at different rates. To prevent evaporation of the developing solution, this process is carried out in a closed container. Each component of the mixture will move a definite distance on the paper in proportion to the distance that the solvent moves. This ratio, Hf = distance component moves/distance solution moves, can be calculated for each component to aid In identification. Hf values are dependent upon the paper, the developing solution, and the amount of sample used. Candies, such as Mix's or Skittles, contain FD&C dyes, sugar, and other organic and Inorganic substances In their coatings. If the coating is dissolved in an acidic solution, the FD&C dyes can be adsorbed from the solution by wool. The dyes can be released from the wool in an alkaline environment. Thus the dyes can be separated from other substances in the coatings. This simplified equation represents the equilibrium involved: Wool + Dye + H+ <====> Dyed Wool+ A solution of ammonia can be used to supply sufficient OH- to reduce the concentration of the H+ and shift the equilibrium to the left releasing the dyes.
What happens when all the water gets evaporated from the sugar solution?
The suger gets left behind while the water evapourates
What happens to plane polarized light when it passes through a solution containing an optically active compound?
The light is either rotated left or right (positive or neagtive) or is not. It is not rotated when a solution contains 50/50 ratio of left rotating and right rotating molecules.
What is left of the solution?
The solvent evaporates from the solution leaving behind the solute
What happens to the paper when you cut it out?
You are left with a hole.
What happen to sugar solution when using a filter paper why?
Suger solution made with water is homogenous so,nothing left, seperate with filter paper .

What happens to the salt solution after evaporation?
the crystallized salt is left behind

What happens when a solution of chlorine is mixed separately with potassium bromine solution and potassium iodide?
It is left as a low hazard
What happens to cobalt chloride paper when its left in open air?
it dissolves its self it Sharon's
How are suspension and solution the same?
They are not the same. If you pass a suspension through a filter paper, all the solid that was in suspension is left behind on the paper. A solution doesn't have any solid bits in suspension - it is all liquid. It will go through a filter paper without leaving any thing behind.
Suppose you prepare 500 mL of a 0.10 M solution of some salt and then spill some of it What happens to the concencentration of the solution left in the container?
If the spill occurs after solution of the salt is complete, the concentration of the solution left in the container remains unchanged, because by definition of solution, the amounts of solvent and solute spilled will have the same proportions as in the original solution.
What Happens when Hydrofluoric acid solution is reacted with a lithium hydroxide solution?
You get a very violent reaction (so don't do this), and you're left with lithium fluoride and water.
What happens when dry apricots are left in pure water and later transferred to a sugar solution?
if dry apricots are left in pure water and later transferred to a sugar solution the apricots become sugar crystals then you can eat the delicious treats.
What happens if you left your paper that you need for the project and it dued tomorrow?
call a friend who was the same paper or ask your teacher if you can get half credit or maybe turn it in late with a pass
