Re: [BKARTS] Questions about methyl cellulose



The way to answer this is to mix up some methyl cellulose with both tap water and with deionized water and check each  mixture with a pH strip. I will try it when I return to school next week (I have pH strips there).

Subject: Re: [BKARTS] Questions about methyl cellulose

I appreciate your thoughts on this. I also do not think that it is  
true that
methyl cellulose is acidic; this may be a question for a chemist.  
There are
now many versions of what passes commercially for methyl cellulose, and
this could be a consideration. I am curious about any research on  
this subject.
