Household ammonia ranges in concentration by weight from 5% to 10% ammonia. [9] Because aqueous ammonia is a gas dissolved in water, as the water evaporates from a surface, the gas evaporates also, leaving the surface streak-free. Its most common uses are to clean glass [10], porcelain, and stainless steel. It is good at removing grease and is ...
Butan-1-ol is one of the "fusel alcohols" (from the German for "bad liquor"), which include alcohols that have more than two carbon atoms and have significant solubility in water. [25] It is a natural component of many alcoholic beverages, albeit in low and variable concentrations.
Wood alcohol C 2 H 5 OH: Ethanol: Alcohol, Rubbing alcohol C 3 H 7 OH: Propan-2-ol: Isopropyl alcohol, Rubbing alcohol C 4 H 9 OH: Butan-1-ol: Butanol, Butyl alcohol C 5 H 11 OH: Pentan-1-ol: Pentanol, Amyl alcohol C 16 H 33 OH: Hexadecan-1-ol Cetyl alcohol: Polyhydric alcohols (sugar alcohols) C 2 H 4 (OH) 2: Ethane-1,2-diol Ethylene glycol: C ...
For example, 100 g of water is about 5.551 mol of water. Other methods of determining the amount of substance include the use of the molar volume or the measurement of electric charge. [7] The molar mass of a substance depends not only on its molecular formula, but also on the distribution of isotopes of each chemical element present in it.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Being extremely soluble in water, ammonium sulfate can "salt out" (precipitate) proteins from aqueous solutions. [ 3 ] [ 4 ] Precipitation by ammonium sulfate is a result of a reduction in solubility rather than protein denaturation , thus the precipitated protein can be resolubilized through the use of standard buffers . [ 5 ]
Reaction stoichiometry describes the 2:1:2 ratio of hydrogen, oxygen, and water molecules in the above equation. The molar ratio allows for conversion between moles of one substance and moles of another. For example, in the reaction 2 CH 3 OH + 3 O 2 → 2 CO 2 + 4 H 2 O. the amount of water that will be produced by the combustion of 0.27 moles ...
