Why does aspirin dissolve in water?
Water is a polar molecule whereas aspirin has no overall charge so the two don't mix very well. Heating the water or adding a few drops of ethanol will make it dissolve a lot faster though. Correction: Aspirin (2-acetoxy-benzoic acid) is a moderately strong acid. It might be called a semi-polar molecule. Ethanol is similar in this respect, and is a good solvent for aspirin. As in all such cases, solubility is determined by the forces between the molecules in solid aspirin compared to the affinity between water and aspirin. The question has no trivial answer. The salts of weak organic acids are usually more soluble than the acids themselves. Adding a base such as sodium hydroxide or ammonia to the water is likely to bring more aspirin into solution - but strictly speaking, the dissolved specis is not 2-acetoxy-benzoic acid, but 2-acetoxy-benzoate.
What is acetylcholine?
Acetylcholine is a neurotransmitter that is released in the synaptic cleft and goes over the sarcolemma down the tubule and promotes the release of calcium from the sarcoreticulum which then binds to proteins on actin which exposes binding spots for myosin to attach to and powerstroke causing muscle contraction.movement, learning, memory, and sleep.

What is the difference between Neutral cure and acetic cure silicone?
Acetic (Acetoxy) silicone sealants release acetic acid (which smells a little like vinegar) as they cure. The will cure faster but do not stick very well compared to Neutral cure types Neutral (meaning neutral alcoxy) silicone sealants release alcohol as they cure, and has almost no smell, but take about 3 times longer to set up than acetic curing sealants. The do have overall a higher "grip" than Acetic types.
Which is the best method for preventing corrosion and an accerate scale to measure the corrosion?
A method of preventing corrosion of metals using silanes. The method comprises applying a first treatment solution directly onto the surface of the metal, wherein the first treatment solution contains at least one multi-functional silane having at least two trisubstituted silyl groups, and wherein the substituents are individually chosen from the group consisting of alkoxy and acetoxy. An optional second treatment solution containing an organ functional silane may also be employed, particularly if the metal is to be painted.
What are examples of pangamic acid?
Pangamic acid is a pure substance sometimes (formerly) named 'Vitamin B15' but chemically known as " 6-(2-Dimethylamino-acetoxy)-2,3,4,5-tetrahydroxy-hexanoic acid ". Its elementary formula is C10H19NO8 for d-gluconodimethylamino acetic acid. molar mass being 281.26 g/mol.[ Ernst Krebs Sr & Jr both patented (1943) and also termed this chemical as "Vitamin B15", though it is not a true vitamin, hasno nutritional value, has noknown use in the treatment of any disease and has been called a "quack remedy". It was banned by the Canadian 'FDA-analogue' (1980)]

What is the designer drug?
Designer drug is a term used to describe psychoactive drugs which are created (or marketed, if they had already existed) to get around existing drug laws, usually by modifying the molecular structures of existing drugs to varying degrees, or less commonly by finding drugs with entirely different chemical structures that produce similar subjective effects to illegal recreational drugs.In the United States, the Controlled Substances Act was amended by the Controlled Substance Analogue Enforcement of 1986, which attempted to ban designer drugs pre-emptively by making it illegal to manufacture, sell, or possess chemicals that were substantially similar in chemistry and pharmacology to Schedule I or Schedule II drugs. Other countries have dealt with the issue differently. In some, they simply ban new drugs as they become a concern, as do Germany, Canada, and the United Kingdom.Most of the best known research chemicals are structural analogues of tryptamines or phenethylamines, but there are also many other completely unrelated chemicals which can be considered as part of the group. It is very difficult to determine psychoactivity or other pharmaceutical properties of these compounds based strictly upon structural examination. Many of the substances have common effects whilst structurally different and vice versa. As a result of no real official naming for some of these compounds, as well as regional naming, this can all lead to (and is anecdotally known to have led to) potentially hazardous mix ups for users. Some common designer drugs include:Opioids* α-methylfentanyl, became well known as "China White" on the heroin market * parafluorofentanyl * 3-methylfentanyl, extremely potent opioid, allegedly used as a chemical weapon by the Russian military in the Moscow theater hostage crisis * MPPP, especially famous due to an impurity in some batches called MPTP which caused permanent Parkinsonism with a single useTryptamine-based* 4-Acetoxy-DiPT, N,N-diisopropyl-4-acetoxytryptamine * 5-MeO-AMT, 5-methoxy-alpha-methyltryptamine * 5-MeO-DIPT, 5-methoxy-di-isopropyltryptamine (also known as "Foxy" or "Foxy Methoxy") * 5-MeO-DMT, 5-methoxy-dimethyltryptamine * AMT, α-methyltryptamine * AET, α-ethyltryptamine * DiPT, N,N-diisopropyl-tryptamine * DPT, N,N-dipropyltryptaminePhenethylamine-based* 2C-B, 4-bromo-2,5-dimethoxyphenethylamine * 2C-C, 2,5-dimethyoxy-4-chlorophenethylamine * 2C-I, 2,5-dimethoxy-4-iodophenethylamine * 2C-E, 2,5-dimethoxy-4-ethyl-phenethylamine * 2C-T-2, 2,5-dimethoxy-4-ethylthiophenethylamine * 2C-T-7, 2,5-dimethoxy-4-(n)-propylthiophenethylamine * 2C-T-21, 2,5-dimethoxy-4-(2-fluoroethylthio)phenethylamine * MDMA, 3,4-methylenedioxymethamphetamine * MDEA, 3,4-methylenedioxy-N-ethylamphetamine * DOB, 2,5-dimethoxy-4-bromoamphetamine * DOM, 2,5-dimethoxy-4-methylamphetamine * TMA-2, 2,4,5-Trimethoxyamphetamine * PMA, a highly dangerous analogue of MDMA responsible for many accidental deathsPCP analogues* TCP, 1-[1-(2-thienyl)-cyclohexyl]-piperidine or thienylcyclohexylpiperidine * PCE, (1-Phenylcyclohexyl)ethylamine * PCPy, 1-(1-phenylcyclohexyl)pyrrolidine * 4-MeO-PCPPiperazine-based* BZP, benzylpiperazine * TFMPP, 3-Trifluoromethylphenylpiperazine, has the unique distinction of being the only drug to be emergency scheduled into Schedule I and then allowed to become legal because the DEA was unable to justify permanent scheduling * mCPP, 1-(3-chlorophenyl)piperazine * pFPP, 1-(4-fluorophenyl)piperazineSteroids* Norbolethone * THG, "The Clear" * Madol (sometimes confusingly referred to as "DMT")Stimulants* Geranamine * 4-Methylaminorex * MDPV * Desoxypipradrol * Diphenylprolinol * MephedroneSedatives* GBL, gamma-butyrolactone, both a precursor to and substitute for GHB * 1,4-Butanediol, another GHB analogue * Methylmethaqualone, an analogue of the sedative methaqualone * MebroqualoneErectile dysfunction* Acetildenafil * Aminotadalafil * Homosildenafil * Hydroxyacetildenafil * Hydroxyhomosildenafil * Piperidino-acetildenafil * Piperidino-vardenafilCannabinoids* THC-O-acetate * JWH-018 - found as an active ingredient in herbal smoking blends such as "Spice". * JWH-073 * JWH-200 * CP 47,497 * CP 55,940
