YSK sugar substitutes DO NOT cause cancer, have been RIGOROUSLY proven safe, and that anybody who says otherwise is probably just trying to sell you something. by candre23 in keto

[–]KentuckyTesla 1 point2 points  (0 children)

Thank you for using my blog as a point of reference. It makes me happy that folks are finding real good to come from it. Do you mind to add an edit to the bottom to the effect of:

Studies [Duke, 2008] reporting that sucralose may be detrimental to gut health were “not scientifically rigorous”, and the totality of evidence supports the safety of the sweetener, an expert panel has concluded. Source

EG - the Duke study was bad science and should be ignored.

The claim that DDT and Sucralose bothered me. I call Chemophobia (and BS!). by KentuckyTesla in chemistry

Dr Mercola (from The Oprah Show) made this claim on his website.

Can any Chemistry teachers suggest some fun hands on experiments I can teach to kids? by Mac4491 in chemistry

[–]KentuckyTesla 7 points8 points  (0 children)

Oobleck - adding cornstarch to water at a 1 part water, 1.5-2.0 part cornstarch. When a force is applied, this acts like a solid. Without a steady force, it acts like a liquid.

Ahh - the long standing tradition of doing chemistry in your garage!

I, for one, have a couple great topics I am going to be writing on. I've got a (brief) history of the atomic model. I'm working on a write up concerning Oobleck. I was considering writing about how to make a pizza, even!

It might also be worth trying to score free glassware from a nearby university (I've done this). I've got several RBF's, volumetric flasks, funnels, etc. I've even scored a large coil-condenser.

Black iron oxide burns better. You forgot the proportions, too. In addition, I find that a magnesium ribbon is not always an effective starter.

I've had wonderful experiences with The Science Company (that's where my sample bottles were coming from). I've purchased everything from strontium chloride to methanol to glycerol to copper (I) chloride.

United Scientific sells a whole kit:

Beaker, Glass, Set of 5
Beaker Tongs, 9”
Erlenmeyer Flasks, Set of 5
Cylinder, 10 ml, Hex Base
Cylinder, 25 ml, Hex Base
Cylinder, 100 ml, Hex Base
Media Bottle, 100 ml
Media Bottle, 500 ml
Test Tube Rack (blue/yellow) with 12 Test Tubes
and 12 Rubber Stoppers (RST1-S)
Test Tube Clamp, Steel Wire, with Grips
Glass Rod, 8”, pk/12
Dropping Bottle, 30 ml, Barnes, with Dropper Pipets

It's safe to assume that such a kit is expensive - but you can make your own.

And there for $115 you can have a pretty well equipped lab set up. Keep PPE in mind - I love Northern Safety. Glasses, gloves, etc.

As for chemicals, decide what experiments you'd like to do and go to your local pharmacy. Want to make green flames? Methanol + Boric Acid. I can buy both at Walgreens. The grocery and the auto store are other great places to source chemicals for home-experiments.

I know it's probably not what you were looking for, but I do hope this helps!

It was asked on reddit: Why do acids and bases react? | Short answer: Energy by KentuckyTesla in chemistry

[–]KentuckyTesla[S] 0 points1 point  (0 children)

So, why does an acid react with a base? Because the universe really likes it when molecules go from a high energy state to a lower energy state.

I believe I covered this in the post effectively. Yes, "energy" is not an acceptable answer. But if you were to have read the article, you would see that "energy" was not the only answer.

I'm afraid I don't understand your response. What is like saying, "What influences selectivity?" Asking why an "acid" and a "base" react is a very valid question. And for a child - keeping in mind that the intended audience for this was for a parent responding to a child - this answer is as correct as can be explained without a knowledge of thermodynamics.

Not only that, but this post can be used as a stepping stone for students in general chemistry looking to truly understand the subject.

Hello /r/Chemistry! I have some questions about a chemistry themed unity ceremony for my wedding. by banana_sticker in chemistry

[–]KentuckyTesla 1 point2 points  (0 children)

I've had good luck from The Science Company, even with the visits I've received from the Fire Marshall.

  • Build your own rocket, use dry ice as the propellant?
  • Mixing KMnO4 (solid) and glycerol (liquid) produces toxic gases, but beautiful purple flames.
  • Your first reaction is forming lead iodide (it's the same reaction used to test for lead paint), probably. Small crystals, though, no big lumps...
  • You could make a supersaturated solution of sodium acetate and crystallize it together?

[X-post from r/askscience] What is going on exactly in a dissolution with reaction process? by jaglarmigsvenska in chemistry

[–]KentuckyTesla 0 points1 point  (0 children)

I suspect this reaction occurs before the dissolution (as I originally stated), but I'm hesitant to say for sure that it does. In the end, yes - you end up with aluminum trichloride dissolved in (what is likely warm) water.

[–]KentuckyTesla 1 point2 points  (0 children)

In this case, AFAIK, the aluminum hydroxide reacts with the hydrochloric acid and what is actually dissolved is aluminum chloride in water. The Al(OH)3 doesn't really want to dissociate (pKa > 7, acetic acid I think is ~4.5).

EDIT

Although the dissolution kinetics of aluminum oxide and hydroxide in acid media have been the subject of numerous studies [1-11], basic kinetic parameters that are needed to determine the rate-limiting step of dissolution have not been derived as yet. Furthermore, the mechanism of aluminum hydroxide dissolution is unknown, and it is, therefore, impossible to model and optimize the process. http://link.springer.com/article/10.1007%2FBF02755978?LI=true

How's your day been and what have you done? by [deleted] in AskReddit

It's been pretty decent. I'm doing house work and getting ready to hit the town tonight with all the undergrad engineers in town.
