2b4m changing color

[studentt]

mixing the powder with toluene and m40% it becomes orange red. after wassing the freebase with water it becomes very dark. dark purple. pitting acid it becomes green/blue/black and no powder at the bottem. what is going on? powder bad quality?

The addition of acid leading to these colors typically indicates complex chemical reactions. If the powder was a freebase, adding acid might convert it back to a salt form, potentially causing precipitation or further color changes due to pH-dependent reactions. The absence of powder at the bottom might suggest that the compound is now more soluble or has reacted to form a different phase or compound. The colors could be indicative of metal ion complexes if there are metal contaminants in your powder. For instance, copper or iron can give these hues upon reaction with certain chemicals

I have done it before, after washing I always have yellow oil. this time after washing it is dark. and i did not put acid

Please tell me about the methods and reagents, so I can see what the issue might be.

Try distilled water. This may also be a problem.
