What is the oxidation for KOH?
K is +1 O is -2 H is +1
Does sodium hydroxide rust the iron?
No. as rust is caused by the oxidation process of: O2+2H2O+4e = 4OH in sodium hydroxide the hydroxide is already present making it harder to form and therefore making rust harder to form. Sodium hydroxide is a rust inhibitor.
Why does a calcium ion have a charge of plus 2?
because for it to become an ion it needs to lose 2 electron which means that it would have 2 more proton than electron and proton is positively charged so it becomes 2+
Mechanism of oxidation of fluorene to fluorenone?
I'm not positive about the correct mechanism, but I can propose one that seems plausible. Oxygen can exist as a singlet or triplet species. The triplet species (O-O with 2 lone pairs and a radical on each O) is the ground state species, so unless O2 is excited, it will most likely react in this manner. Using that assumption, O2 can abstract a proton radical from flourene to form a fluorene radical (with the radical at the benzylic position). This is the initiation of a radical chain process. Next, the peroxy radical can attach to the fluorene radical (thus terminating the chain). Alternatively, another O2 molecule can attach to the fluorene radical. This peroxy fluroene radical can abstract a proton from a fluorene molecule, propogating a fluorene radical. In either case, the resulting species is a peroxy fluorene molecule. Now, you can draw a mechanism where a hydroxide anion (the reaction is run in base) pulls off the remaining benzylic proton, pushing electrons into a carbon to oxygen pi bond, and breaking the oxygen-oxygen single bond to release hydroxide. As I said, I have no evidence for this mechanism, just using my chemical knowledge and experience.
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
What molecule loses a proton to form the nitrate ion?
The molecule of nitric acid lose a hydrogen atom, not only a proton.
A substance that accepts a proton?
A substance that accepts a proton is called a base. Bases are typically classified as proton acceptors because they can donate a pair of electrons to form a new chemical bond with a proton. This process results in the formation of a conjugate acid.
Is hydroxide ion basic?
Yes, hydroxide ion (OH-) is a basic ion because it can accept a proton (H+) to form water (H2O), resulting in an increase in the concentration of hydroxide ions in solution.
Is ammonia is soluble in water or a polar molecule?
Ammonia form in water ammonium hydroxide - NH4OH.
What molecule is produced when two electrons and one proton combine in photosynthesis?
The reduced form of NAD+ is NADH.
Sodium hydroxide an acid or base?
Sodium hydroxide is a base. It is a strong base that dissociates completely in water to form hydroxide ions.
A conjugate acid-base pair differs by several h ions?
A conjugate acid-base pair differ by one proton (H+) ion. The acid loses a proton to form its conjugate base, while the base gains a proton to form its conjugate acid. This proton transfer results in the formation of a conjugate pair.
Name two ions that are the products of the dissociation of water?
Another way to describe the dissociation of water is as follows where two water molecules form a hydronium ion (essentially a water molecule with a proton attached) and a hydroxide ion
Is ammonia acid basic or neutral?
Ammonia is a basic compound because it can accept a hydrogen ion (proton) from water to form ammonium hydroxide, which increases the concentration of hydroxide ions in solution.
What are acid and base?
Acids, bases and salts are chemical compounds. Examples are: Acids: sulfuric acid, nitric acid, stearic acid, phosphoric acid, hydrofluoric acid etc. Bases: sodium hydroxide, magnesium hydroxide, calcium hydroxide, lithium hydroxide etc. Salts: sodium chloride, gallium arsenide, potassium bromide, uranyl nitrate etc.
What is the conjugate base of hydroxide ion?
The conjugate base of hydroxide ion (OH-) is water (H2O). The conjugate base is formed when an acid (H+) donates a proton to the hydroxide ion to form water.
Ethers can be formed by what reaction?
Ethers can be formed by the Williamson ether synthesis, a reaction involving the nucleophilic substitution of an alkyl halide or alkyl sulfonate with an alkoxide ion. This reaction typically takes place in the presence of a strong base, such as sodium or potassium hydroxide. Another way to form ethers is through the acid-catalyzed dehydration of alcohols, where an alcohol molecule loses a water molecule to form an ether.
