In a paper chromatography analysis, three pigments, A, B, and C, were dissolved in a solvent. A is slightly polar, B is highly p

olar, and C is moderately polar. List in order how these will appear on the surface of the chromatography strip starting from the applied spot at the origin line.

Answer:It would depend on the eluent solvent what we use ,If we would use a polar solvent than B will be appear first followed by c and then A on the chromatography strip.

If we use non-polar eluent solvent than A will be separated first followed by C and thenB on the chromatography strip.

Explanation:

Separation using paper chromatography is dependent upon the polarity of various  pigments .

A polar pigment would move ahead in case of polar solvent used and a non-polar pigment would move ahead when we use a non-polar solvent.

So separation would occur in order of polarity  of various pigments in a given solvent.

The amount of distance travelled by each component (or pigment or spot) can be calculated using the formula for retention factor:

Rf= Distance travelled by pigment spot or solute/Distance travelled by eluent solvent

Rf= Retention factor

Retention factor is basically the ratio of distance tarvelled by the pigment or spot to the ratio of distance travelled by the solvent.

Justin mixed two clear liquids together during an experiment and made the following observations:
svp [43]

Answer:

B. A chemical change occurred which caused the liquid's physical properties to change.

Explanation:

The reduction of the temperature of the system meant that the reaction absorbed heat energy from it. This shows that a chemical reaction was in progress. New products were formed, and this is proved by the change in the color to blue.
