I bought a can of acetone recently. I called the manufacturer and they said that the acetone was 99.5 percent pure. This is not good enough for me. I need it as pure as possible. I have tried tossing in anhydrous magnesium sulphate (about 40 grams per litre), shaking well for a couple minutes...
I guess I could use a multi-solvent system. My compound is extemely soluble in water and so is its impurity, even at room temperature, so water is not a good solvent for this. But my compound is completely insoluble in acetone while its impurity is soluble in acetone. So I could dissolve my...
I have read online that suppose I am trying to purify compound_A, which contains an impurity, let's call that compound_B, that the solvent that I choose for recrystallization must either:
1) dissolve compound_A but not compound_B, so that compound_B can be filtered out after dissolving...
Thanks for the replies! I have read a lot about crystallization and I will be doing some experiments over the next couple of days. I will update this thread if I have any questions.
Hi, I am trying to recrystallize salt from methanol. I am having trouble. This is exactly what I did:
I dissolved a gram of salt into 20 ml of methanol (the bottle I have says methyl hydrate but I read online that it's the same thing as methanol). Then I made a hot water bath. I put a pyrex...
Sorry for this late reply, I have been very busy with a family emergency!
I have done many experiments and trial and errors, but there is one problem that I cannot solve. The pill is always too brittle. It is in a pill form when I take it out of the press, but when handling, it just completely...
Little bit of help for science fair project please!
Hi guys, I am 13 years old and I am a new member on this forum and I need help with a science fair project.
For my project I am showing how companies make tablets so I need to learn how to make a tablet. I did some research but some of the...
