ebonite

mmetecaliskan:
it seems to be easy but i couldnt find the answer of this question.I hope one of you will help me to find the answer .
now my question is :

why  do ebonite attract pepper but not salt

P:
This is just a guess based on logic  -  please correct me if I'm wrong.

Ebonite is a plastic right? An organic polymer!

In chemistry - 'like' dissolves 'like'   - also polymers get charged and attract.

Pepper  -  being organic  -  is attracted electrostatically to the organic polymer ebonite. Salt - being ionic - is not.

please correct me if I'm wrong.    :)
