Paper Chromatography

Hey Ethan, Mia, and Harper! Which of the following best describes the stationary phase in paper chromatography?

• The solvent used

• The paper itself

• The sample being tested

• The air around the setup

Hey there, Mia and Zoe! Have you ever wondered what happens to the components of a mixture during the exciting process of paper chromatography?

• They all move at the same rate

• They separate based on their solubility and affinity to the paper

• They dissolve completely

• They evaporate

Hey there, science enthusiasts! 🌟 Which of the following is a key factor that affects the results of paper chromatography? Let's see if Isla, Mia, or Avery can figure this out!

• The color of the paper

• The temperature of the room

• The type of solvent used

• The size of the paper

Hey there, curious minds! Benjamin, Lily, and Olivia are exploring the fascinating world of science. Can you help them figure out the main principle behind chromatography?

• Filtration

• Separation based on different affinities

• Evaporation

• Condensation

Hey there, food enthusiasts! Have you ever wondered what magical role paper chromatography plays in the food industry? Let's find out!

• Measuring pH levels

• Testing for food additives

• Cooking temperatures

• Nutritional analysis

Hey there, students! Have you ever wondered why we spot the sample on chromatography paper? Let's find out!

• To create a beautiful design like Olivia's art project

• To mark the starting point for an exciting separation adventure

• To measure how far our samples travel, just like Jackson's race!

• To dry the paper, so Michael can use it for his next experiment

A technique used to analyze pigments in spinach leaves is shown in the diagram below.

This technique is known as

• paper chromatography

• gene manipulation

• dissection

• staining

Base your answer to question 82 on the results of an experiment using plant pigments represented below and on your knowledge of biology. Which phrase could be used to describe this technique?

• the use of chromatography to separate molecules in a mixture

• the use of cut leaves to observe certain colors

• using indicators to determine pH

• using dichotomous keys to identify plants

This setup is part of the technique known as

• electrophoresis

• biological staining

• dissection

• chromatography

In order to compare the composition of the pigments on the suspect's jeans to the pigments of the plants at the home, the forensic scientist should use

• restriction enzymes

• genetic engineering

• paper chromatography

• receptor molecules
