Is Ibuprofen a mixture or pure substance?

Answer 1

ibuprofen is just a brand name for the actual chemical, an aromatised propanoic acid, which gives the desired pain relief effect. Most commercially available ibuprofen, in painkillers, is often sold in a mixture with paracetamol and caffeine so that the pain relief effects are felt faster.

So in answer to your question Ibuprofen itself is a pure substance, but most over-the-counter Ibuprofen tablets etc are sold as mixtures with other pain relievers and caffeine.

Answer 2

Ibuprofen itself is a pure substance. However, when it is made into a pill or capsule, it becomes part of a mixture.

Answer 3

Ibuprofen is a pure substance. It is a crystalline solid compound with a specific chemical structure and composition.
