Great job Robert Bruce Thompson! Can"t wait for next video

very soothing watching this

@TheHomeScientist Hey, was wondering if you can use the principal of the Marquis Reagent to detect Formaldehyde in a sample. For example, old insulation called UFFI contained formaldehyde. Could we add sulfuric acid and a drug and check for color? My point again is to find out weather the sample contains Formaldehyde... Thanks for your comments!

good day sir! i was wondering where i could buy this marquis reagent because we were proposing to create an invention for our chemistry. we'll be using a nail polish with a marquis reagent as a drug detector. please reply as soon as you read this. thank you in advance.

Is it a problem if I test using impure, dilute, powdered mixtures of active drug in relatively much larger quantities of tablet excipients, do I need to beware of potentially 'false' colour changes due to various tablet coatings, fillers, colouring agents, etc. rather than the active ingredient itself? Thank you for the great video :-)

I have a question regarding your results. I believe you said that the Chlorpheniramine maleate sample provided inconclusive results with both wells, but at the end, the contents of the well turned a green color. Would you still record this as no reaction, and if so, why?

would this work with a urine sample,or would it be too dilute for this type of test. i think those types of tests(homekits) use some type of an antibody reaction.

This is really good! I've made ammonium metavanadate yesterday and was looking for a good use. This is a great idea. I am really wondering about the chemistry behind these tests. Why do you get those specific colours? What happens?

Which color isn't intense?

Would caffeine or theobromine give a positive reaction?

Can you prepare your own Mecke reagent? i can't seem to find selenious acid or selenium dioxide. is it possible to a home scientist to get a hold of what is needed in Mecke?

I like your way of thinking... even split bubble wrap. How big though the small or the larger bubbles?

as usual - top notch science here! thank you!

Those colours were intense.

Nice

This man sounds like a robot

Thank you,, :)

So any of these reagents will pop hot on any number of everyday drugs and substances. Gotcha.

cool video

@bletnahuj That would (a) produce hot sulfuric acid fumes, and (b) cold sufuric acid is scary, hot sulfuric acid is terrifying. It's easier just to buy drain unblocker conc. sulfuric acid.
