How to Do a Paper Chromatography Experiment at Home: Step-by-Step Guide with Diagrams

Paper chromatography is a technique used to separate components of a mixture. It involves using a stationary phase (paper) and a mobile phase (solvent) to separate compounds based on their solubility and attraction to the paper.

  • Paper chromatography separates mixture components based on solubility differences
  • The process involves a stationary phase (paper) and mobile phase (solvent)
  • More soluble compounds travel further up the paper
  • The resulting pattern of separated compounds is called a chromatogram
  • Rf values are calculated to quantify how far compounds travel

Paper Chromatography Experiment

This page provides an overview of the paper chromatography experiment and its key components. Paper chromatography is a fundamental technique in chemistry used to separate and analyze mixtures.

The process begins by placing a small spot of the sample near the bottom of a strip of chromatography paper, ensuring it doesn't touch the solvent. The paper is then partially immersed in a solvent, such as water, which acts as the mobile phase. As the solvent moves up the paper by capillary action, it carries the dissolved compounds with it.

Definition: Chromatography is a technique for separating components of a mixture based on their different affinities for a stationary phase and a mobile phase.

Different compounds in the mixture have varying solubilities in the solvent and different attractions to the paper fibers. This causes them to travel at different rates up the paper, resulting in separation.

Vocabulary: The stationary phase in paper chromatography refers to the paper itself, while the mobile phase is the solvent that moves along the paper.

The separation process continues until the solvent reaches near the top of the paper. At this point, the paper is removed and allowed to dry. The resulting pattern of separated compounds is called a chromatogram.

Highlight: More soluble compounds are carried further up the paper than less soluble ones, leading to separation based on solubility differences.

To quantify the results, scientists calculate the Rf value retardationfactorretardation factor for each compound:

Example: Rf = distance traveled by spot / distance moved by solvent

This value helps in identifying and comparing compounds across different chromatography experiments.

Quote: "Chromatography is a technique for separating components of a mixture."

The paper chromatography experiment is widely used in various fields, including forensic science, food industry, and pharmaceutical research, due to its simplicity and effectiveness in separating complex mixtures.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
