Step-by-step solution for: Chromatography Home Learning Worksheet GCSE
The image shows a worksheet titled "Chromatography" from a chemistry topic. The task involves understanding and applying the principles of paper chromatography. Below is a detailed explanation of how to solve the problems presented in the worksheet.
---
#### 1. Labeling the Diagram
The diagram on the left represents a setup for paper chromatography. The labels need to be filled in based on the components of the experiment:
- Solvent: This is the liquid that moves up the filter paper by capillary action.
- Ink spot: This is the sample (ink) placed on the filter paper at the baseline.
- Filter paper: The paper used to separate the components of the ink.
- Beaker: The container holding the solvent.
- Baseline: The starting line where the ink spot is placed on the filter paper.
#### 2. Ordering the Steps of Paper Chromatography
The steps provided need to be numbered in the correct order:
1. Draw a baseline on the filter paper with a pencil.
- This is the first step, as it establishes where the ink spot will be placed.
2. Add a spot of ink to the baseline.
- After drawing the baseline, the ink sample is placed on it.
3. Place the filter paper into the beaker containing the solvent.
- The filter paper is then immersed in the solvent, which will start moving up the paper.
4. Remove the filter paper just before the solvent reaches the top.
- Once the solvent has moved sufficiently up the paper, the filter paper is removed to stop the process.
5. Place a lid onto the beaker.
- This step ensures that the solvent does not evaporate too quickly during the experiment.
#### 3. Completing the Paragraph
The paragraph discusses the separation of mixtures using physical methods like chromatography. The correct options are:
- The different parts of a mixture are chemically bonded so they can be separated by physical methods such as chromatography.
- Explanation: Chromatography separates components of a mixture based on their differing affinities for the stationary phase (filter paper) and the mobile phase (solvent). This is a physical separation method, not a chemical reaction.
- An example of a mixture is air, which contains oxygen, nitrogen, carbon dioxide, and other gases.
- Explanation: Air is a homogeneous mixture of various gases, making it a suitable example.
#### 4. Filling in the Gaps
The gaps in the paragraph need to be filled with appropriate words:
- As you place the filter paper into the solvent, the solvent seeps through the paper. The ink spot separates into different dyes and each dye travels at a different speed. This produces a pattern called a chromatogram, which can be used to identify patterns of other inks.
- Seeps through: The solvent moves upward through the filter paper.
- Different speeds: Each component of the ink moves at a different rate depending on its affinity for the solvent and the paper.
- Chromatogram: The pattern formed on the filter paper after the experiment is complete.
