Other Names For Water

The IUPAC name for water is, actually, water. The alternative name is oxidane. The name oxidane is only used in chemistry as the mononuclear parent hydride to name derivatives of water.

Other names for water include:

• Dihydrogen monoxide or DHMO
• Hydrogen oxide
• The polarized form of water, H+ OH-, is called hydron hyroxide.

The word “water” comes from the Old English word wæter or from the Proto-Germanicwatar or German Wasser. All of these words mean “water” or “wet.”

Is H2o2 A Balanced Equation

In reality, it takes two molecules of hydrogen peroxide for this reaction to happen, and it produces two molecules of water and one molecule of oxygen, shown below: Using coefficients, this is how the balanced equation is written: 2 H2O2 2 H2O + O2 , which reflects more realistically how the reaction occurs.

Basic Salts Containing Hydroxide

In some cases the products of partial hydrolysis of metal ion, described above, can be found in crystalline compounds. A striking example is found with zirconium. Because of the high oxidation state, salts of Zr4+ are extensively hydrolyzed in water even at low pH. The compound originally formulated as ZrOCl2·8H2O was found to be the chloride salt of a tetrameric cation 8+ in which there is a square of Zr4+ ions with two hydroxide groups bridging between Zr atoms on each side of the square and with four water molecules attached to each Zr atom.

The mineral malachite is a typical example of a basic carbonate. The formula, Cu2CO32 shows that it is halfway between copper carbonate and copper hydroxide. Indeed, in the past the formula was written as CuCO3·Cu2. The crystal structure is made up of copper, carbonate and hydroxide ions. The mineral atacamite is an example of a basic chloride. It has the formula, Cu2Cl3. In this case the composition is nearer to that of the hydroxide than that of the chloride CuCl2·3Cu2. Copper forms hydroxyphosphate , arsenate , sulfate , and nitrate compounds. White lead is a basic lead carbonate, 2·Pb2, which has been used as a white pigment because of its opaque quality, though its use is now restricted because it can be a source for lead poisoning.

What Is Skeleton Equation

Skeletal chemical equation is a representation of a chemical reaction using chemical formulae of reactants and products. In skeletal chemical equation the mass no of elements in reactant side is not equal to the mass no of elements in product side. For example: Mg + O2 MgO, its a skeleton equation.

As A Nucleophilic Reagent

The hydroxide ion is intermediate in nucleophilicity between the fluoride ion F, and the amide ion NH2. The hydrolysis of an ester

R1COR2 + H2O R1COH + HOR2

also known as saponification is an example of a nucleophilic acyl substitution with the hydroxide ion acting as a nucleophile. In this case the leaving group is an alkoxide ion, which immediately removes a proton from a water molecule to form an alcohol. In the manufacture of soap, sodium chloride is added to salt out the sodium salt of the carboxylic acid this is an example of the application of the common ion effect.

Other cases where hydroxide can act as a nucleophilic reagent are amide hydrolysis, the Cannizzaro reaction, nucleophilic aliphatic substitution, nucleophilic aromatic substitution, and in elimination reactions. The reaction medium for KOH and NaOH is usually water but with a phase-transfer catalyst the hydroxide anion can be shuttled into an organic solvent as well, for example in the generation of the reactive intermediate dichlorocarbene.

How Much Of The Earths Surface Is Covered With Water

In his well-known poem The Rime of the Ancient Mariner, Samuel Coleridge wrote Water, water everywhere, Nor any drop to drink. The narrator was talking about being out on the ocean, but not having any water because he had killed an albatross . About 75% of the Earths surface is water. The major constituent of the human body is water. This simple molecule plays important roles in all kinds of processes.
