there are crystals stuck to the top of the phenol-chloroform-isoamyl alcohol bottle. What are these?

Question

These are chunky crystals stuck to the glass, are cloudy and are above the surface of the liquid. This is a brand new, unopened bottle of 25:24:1.

Answer 1

Phenol is a solid with a melting point of 40.5 °C.

The chloroform and isoamyl alcohol are the solvents for this solution. The Phenol has come out of the solution and condensed on the sides of the glass bottle.

All you need to do is agitate (swirl) the contents of the bottle until the Phenol redissolves (before you open the bottle).
