Q

IN LAB YOU TESTED THE RATE OF DIFFUSION OF POTASSIUM PERMANGANATE AND METHYLENE BLUE THROUGH AGAR. WHICH DYE MIGRATED AT A SLOWER RATE? WHY?

A

Noticed visually by black flecks on filter paper

76
Q

HOW WAS THE PRESENCE OF COPPER SULFATE IN THE FILTRATION BEAKER VERIFIED?

A

Lugol’s Iodine

78

Liquid

81
Q

IN LAB, USING DIALYSIS TUBING AND METHYLENE BLUE, DOES METHYLENE BLUE STAY INSIDE THE TUBING OR EXIT?

A

EXIT

82
Q

IN LAB, USING DIALYSIS TUBING AND METHYLENE BLUE, WHY DOES METHYLENE BLUE EXIT THE TUBING

A

It is small enough to exit therefore moves down its concentration gradient

83
Q

IN LAB, USING DIALYSIS TUBING, DID BLUE DEXTRAN EXIT THE TUBING? WHY?

A

No. blue dextran could not escape due to its size. blue dextran’s molecular weight is too large for it to travel across the dialysis membrane’s pores
