Formic acid (from Latin formica 'ant'), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH and structure H−C(=O)−O−H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants.
Vapor-liquid Equilibrium for Formic acid/Water [4] P = 760 mmHg BP Temp. °C % by mole water liquid vapor 102.3: 4.05: 2.45 104.6: 15.5: 10.2 105.9: 21.8: 16.2 107.1 ...
In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction
Calcium formate is the calcium salt of formic acid. It is also known as E238. Under this E number it is used as an animal feed preservative within EU, but not in foods intended for people. [5] Calcium formate is stable at room temperature, [5] is flammable and forms orthorhombic crystals. [2]
As a salt of a weak acid (formic acid) and a strong base (sodium hydroxide) sodium formate reacts in aqueous solutions basic: + + A solution of formic acid and sodium formate can thus be used as a buffer solution.
Simple organic acids like formic or acetic acids are used for oil and gas well stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid (HCl) or mixtures of HCl and hydrofluoric acid (HF). For this reason, organic acids are used at high temperatures or when long contact ...
This hyrophilic tunnel is located in the middle of FwdBD and FwdA active sites and is convenient for formic acid and formate transportation [pKa = 3.75]. [2] The tunnel has a bottleneck appearance which consists of a narrow passage and a wide solvent-filled cavity located at the front of each active site. [2]
Performic acid is synthesized by the reaction of formic acid and hydrogen peroxide by the following equilibrium reaction: . Synthesis of Performic acid. Synthesis of pure performic acid has not been reported, but aqueous solutions up to about 48% can be formed by simply mixing equimolar amounts of concentrated aqueous reactant solutions. [4]
