Reaction equation of Glucose and hydrochloric acid in solution
« on: February 08, 2022, 11:34:34 PM »
 I've been trying to figure out the equation for the reaction between glucose and hydrochloric acid for a couple of days, but none of my searches are yielding results.
My class hasn't learned any organic chemistry yet, which I assume is where this type of reaction would be covered.
I have tried to ask chemistry teachers at my school for help, but they weren't able to give me an answer either.

For specifics, these are the reactants:

2.0 mol dm-1 Glucose solution
Hydrochloric acid solutions with concentrations ranging from 0.2 mol dm-1 to 1.0 mol dm-1
All the solutions are made with distilled water

In each reaction, 25 mL of the glucose solution is mixed with 25 mL of the HCl solution.

As a note: while I haven't been able to find reaction equations of glucose and HCL, I have found reaction equations for glucose + Sulfuric acid. Would the reaction be similar for any combination of glucose and a strong acid?

If further information is needed, I'll try and provide it.
If I have broken any forum rules, please tell me and I will fix it.

Why do you assume there is a reaction taking place?

I assumed there was a reaction because I've seen it work with sulfuric acid. My expectation was that since one strong acid had a reaction, that other strong acids would as well.

Concentrated sulfuric acid is a liquid and is a strong charring agent (it is quite efficient at stealing water from compounds, even those that technically don't contain water, just some H and OH located close by in the structure). Especially in the case of more complicated molecules (like hydrocarbons) this is rarely a nice, stoichiometric process, that can be written as a simple reaction equation.

Hydrochloric acid doesn't work this way, it doesn't exist without water at all.
