Thank you for such a simple and available "solution" to the subject of boron detection.

i am no scientist but i do enjoy watching your videos and somewhat learning about this stuff. I have no clue what it all means but it is interesting to me :) You do a very good job

I wish I was knowledgeable enough to contribute a relevant comment about this video. Your videos have inspired me to take more chemistry classes at my university. I look forward to more.

thank you that was well explained and very helpful!

Why am i only now learning about this channel.

this is really good :)

Thank you for posting this. Im going to be testing a Boron vitamin from amazon with this test. Crush up a pill into water and dilute thru different ratios. If im getting this right ill use a fuel stove methanol and mix with tumeric to create my yellow dye. if i see a colour change ill know im dealing with sugar pills like some reviews have stated.

Nice video

I'm looking at an idea and you might be able to point me in a direction. Raisins soaked in gin works to relieve arthritis pain for some people. It is a complex set of nutrients and minerals involved in the recipe but I'm wondering if you know where I could get a handle on the various extractions that happen? I'm interested specifically in boron in this case. I'm thinking the ethanol makes the boron more easily available to our metabolism. Thanks for your boron/curcumin testing video. I might use that method for testing the raisin/gin mixture. Thanks

I'm curious to test samples to better understand if the presence of boron exists in stones. Would this test work with dustfalkes from the stones?

HA! Mark 1 eyeball! good stuff!!

Hi Robert, I live in Indonesia, food manufactuers add boric acid to food here for various reasons. I just found out that is not healthy. Your video will allow me to figure out which food has this. Food labeling in this environment is not reliable. Thanks so much for sharing. Awesome.

Nice

Nice test... one question... I happened to have some boric acid i'd made up a month back or so... mixed it in with water mixed in the turmeric directly and no color change was noticed... so i went to the laundry room, grabbed the borax and sure enough red. Is the limitation due to the acidity of boric acid vs sodium tetraborate? or is it due to how they dissosciate differently in solution? Have you tried boric acid?

Can this test be used to determine boron levels in anthracite coal, or shale? And if so, what would the procedure be?

i found 3 tons of sheep wool in an abandoned factory nextdoor, its 20 30 years old and in fine conditiotn so i need to test it for borax treatment. ill see if i can test direct on the wool. thanks!

Would the test work to detect borosilicate glass ?

Robert, well i just added some baking soda to the mix and nothing happened... so i added more.. added until saturated. nothing. Forgot how slowly the boric acid disolves in cold water. went out to the shop and upon my return the baking soda had all been used up. added a bit more and saw the change. So my guess is that the boric acid is only miscible and not soluble? but naw all acids are soluble right? the reaction occurs when the boron forms a complex ligand? something like the dissosciation of Cu2SO4 in citric acid. so reading wiki it states that boric acid will form polyborates just above pH7... is that what would be expected of Na2B4O7·10H2O as is disolves?

I just performed this test according to EPA standards (which called for boric acid) and nothing happened. Can I use grocery store Borax for my standards?

Is rosocyanine toxic?

hey have ur book i even found some errata i emaikled u through ur site though i was wondering if u tested positive for boron can u get it out? cheers

RBT, did u notice the Exponential color change was not what you might expect for the 4th well compared to the 3rd well, the 4th well seams darker than the 3rd. can you explain or hazzard a guess as to why, its unlikely it was the camera as all the other well's showed a nice discernible difference.

I did notice that - my guess would be because an imperfect droplet method was used, either each drop was a different size, or the solution obtained with the pipette wasn't fully mixed. Because of that, it was good that 8 wells were used instead of one or two.

I can't express how happy I am to find this video, especially since my group will be testing the presence of borax in food in a few days. I am curious, however, with the procedure that we will be using. Why do we need to add Ammonium Hydroxide and HCl to the curcumin paper after it gives off a reddish hue?

Fake!! The turmeric powder extract turns red in an alkaline solution. Here, borax is alkaline near pH 9.

My tincture turned greenish, when putting soil and perfume (EtOH+PlantOils+Ether) in it. Wondering if that reaction has a meaning too..?!

Rosocyanine in pure form is a glassy dark green crystalline substance, but forms deeply red solutions at even very low concentrations. It is only very slightly soluble in lower alcohols and other organic solvents, but solubility increases slightly with the addition of acids.

I like curcumin

OMG! i'm going to link to this vid! yuppers! =^-^=
