What is the difference between hydrocortisone acetate and hydrocortisone?
Q. My doctor told me to put hydrocortisone cream on surgical scar tissue I have on my ear and at the store i found something (cheaper) that said it contained "hydrocortisone acetate 1.0% (equivalent to hydrocortisone 1.0%)". When I called my doctor to ask him if it was alright he said it wasn't the same thing, but I don't know if he even knew what I was talking about. So is it really different at all, since the product container said they are equivalent?

A. It's the same thing (at least, as far as I know--you may have to ask him to explain, as it's possible he knows something that I don't about the difference). The important ingredient is the hydrocortisone. It comes in various different strengths from 0.1% to 2.5%. The larger percent ones are prescription only. I have a feeling though, that he may have misunderstood what you said.

Using denatured alcohol and calcium acetate, is it possible to make a fuel gel?
Q. I'm doing a science fair project , and I want to do it on making a "fuel gel" out of easily available materials. I have attempted to make the gel using various different methods, such as crushed eggshells, vinegar and denatured alcohol, or calcium acetate and denatured alcohol and some other versions, but I still have not been able to produce a "fuel gel"... Does anyone have any other tips or suggestions on how to make one???

A. I have a book that says use 9 parts ethyl alcohol (you could use denatured) to one part Calcium Acetate saturated solution. The keys are saturated Calcium acetate, and at least 95 % alcohol. You have to add a lot of calcium acetate to water to saturate it. I have done this, and it did work, so keep trying.

What weight ratio of acetic acid to sodium acetate should be used to prepare a buffer of pH 4.55?
Q. What weight ratio of acetic acid to sodium acetate should be used to prepare a buffer of pH 4.55? The pKa of acetic acid is 4.76. The weight ratio is defined as grams of acetic acid to grams of sodium acetate. (Hint: compute to mole ratio of acetic acid to sodium acetate and then convert the mole ratio to a gram ratio using the molecular weight of acetic acid and sodium acetate as conversion factors.)

A. 4.55 = 4.76 + log [CH3COO-] / [CH3COOH] 10^-0.21 =0.616 = [CH3COO-] / [CH3COOH] [CH3COOH] / [CH3COO-] = 1 / 0.616 =1.62

What exactly is acetate and how do artists use it?
Q. I've seen acetate used as a template before, is it like plastic? What else can it be used for? Can this be found at crafts and arts stores? Thanks for your help...
Asked by immaryofnazareth - Fri Jul 11 14:08:43 2008 - - 2 Answers - 0 Comments

A. Acetate is a clear plastic sheet. It can be used on Over Head Projectors (OHP) to give presentations, you can write/ draw on it using special OHP acetate pens or magic markers. Artists can use it with an OHP to enlarge images to 'trace' on to walls, canvass' or similar vertical surfaces. It can be bought in A4 sizes from any good office supplier, certain types, (it will specify on the box),can be used with an ink jet printer, so you can print from your computer. Hope this helps.

How do I add more acetate to my killing jar without risking my fly buzzing away?
Q. Obviously, I ran out of acetate, 'cuz when I checked, my fly specimen was having a filed day!
Asked by King Edmund the Just - Thu Mar 27 21:35:45 2008 - - 1 Answers - 0 Comments

A. You can put the whole jar in the freezer for awhile. That will slow the fly down enough to let you get the lid off and recharge. Work quickly, though. You MIGHT be able to tap the bottom of the jar gently on something softish (phone book, your knee, etc.) and get the loosened lid off and add in the ethyl acetate while continuing to tap. The tapping helps keep the fly on the bottom, but this would be a last resort. Go entomologists!

Q. I have a bug bite and have been trying to find on the internet if it's safe to put on a cream that is 2% diphenhydramine hydrochloride and 0.1% zinc acetate. I hate to wait until Monday to ask my doctor so thanks for any info you may know.
Asked by motherhood - Sat Jul 5 21:46:41 2008 - - 2 Answers - 0 Comments

A. if the topical cream contains only 2% of diphenhydramine which is used to treat allergies, then it should be safe as I heard many women were prescribed Benadryl by their doctors for cough, flu and related illness which was more penetrating cuz it was in oral form but of course you may want to consult your doctor first if you really want to be sure. topical cream doesn't penetrate deeply into your bloodstream so i wouldn't worry about it. for zinc acetate, i found this website which says it is also safe good luck and congratulations=).

A. Rotovap is best it is really just vacuum distillation. If your sample is stable to ~80 C simple distillation could be used or good old fashion put it in an evaporating dish in a fume hood and come back in a couple hours... Too dilute for TLC... not much there

Why is aspirin soluble in ethyl acetate and insoluble in water?
Q. Why is aspirin soluble in ethyl acetate and insoluble in water? Explain this based on intermolecular forces and the generalization "like dissolves like". I am stumped. I looked it up and it said that ethyl acetate was polar. So is water, but, aspirin is also insoluble in cyclohexane which is nonpolar. Please help me. This is due tomorrow.

A. Actually, ethyl acetate is also nonpolar. At least, it is fair to say that water is much more polar than ethyl acetate. Therefore, aspirin can only be dissolved in ethyl acetate, since both are nonpolar(ish).

What's an acetate used for in regards to comics?
Q. I was just wondering what an acetate is in reguards to comics. On ebay I saw an acetate which was a transparent film thing with the cover of a comic printed on it in black, No color or anything. Were these used in the creation of the comic? Are they valuable? Is it something I should look for when collecting original comic art? I really have no clue what these are used for..
Asked by FS - Fri Sep 12 14:31:42 2008 - - 1 Answers - 0 Comments

A. The acetate sheets were used to color the comic pages for printing. It must have been a sheet of black (or line art) that you found on Ebay. Yes it was sued to pprint out the comic. So it's original and possibly of some value. It's considered production art and is of value to a collector. Some of it is worth a lot, some isn't - it depends on how interested people are. Also, it is not original art work and thus less valuable.

This Instructable will show how to make sodium acetate using common household ingredients. No special equipment of measuring is required. You can pretty much eyeball the whole process.
