Investigation Into Photosythesis

Question 1

How do u extract photosynthetic pigments

Answer 1

Use a pestle and mortar to grind leaf with a extraction solvent

Question 2

Outline how paper chromatography can be used to separate photosynthetic pigments

Answer 2

• use capillary tube to spot pigment extract onto pencil start line. Cm able bottom of paper
• place chromatography pepper in solvent
• allow spent to run until it almost touches the other end of the per. Pigments moe different distances

Question 3

What is RF values

Answer 3

Ratios that allow compares of how far molecules have moved in chromatograms

Question 4

How to calculate RF value

Answer 4

Instance between origin and centre f pigment spot/ distance between origin and Solvent front

Question 5

Purpose and principle of paper chromatography

Answer 5

Molecules in a mixture are separated based on their relative attraction to the mobile phase vs the stationary phase
