Does anyone know about a feasable way to make Methanol and/or Ethanol
from the Glycerin leftover from Biodiesel production? Also: How can I
transform the methane obtained from manure fermenting (in a digester)
into Methanol and what kind of production can I expect from both these

I have an embarrassing question on how to connect a pH electrode to pH
meter.
In my lab, the way pH meter is setup is as follows: a Fisher glass-body
combination electrode

I'm preparing chemicals for a qualitative analysis lab.  We're mixing
some 0.1 and 0.2 M solutions and getting precipitates.  Here's my problem:
One of the solutions is Na2S.  Whenever it is mixed with one of the acid
solutions (HCl, HNO3, or H2SO4), I get a cloudy white result.  ...

Has anyone has seen this process in practice at industrial scale ?   I
am concern that my HCL get contaminated with Sulfuric Acid.
The process is  2NaCl + H2SO4  --->  2HCL (g)  +  Na2SO4(s)
I am interested to learn what if this reaction is started with a 50%

Hello Dear All
As an electrical engineer Student, I want to gather some information
in medicine which absolutely your guides will be so helpful.
My question is below:

Could someone check fig 1 of the following website on gratings? The
figure 1 shows that diffraction angles for first order (on either side
of the grating normal) from a reflection grating quite different.
