Can acetic acid make our life more good?

 By using X-ray diffraction and freezing point reduction, it has been demonstrated that molecular carboxylic acid with low molecular weight can exist in both solid and liquid, and even in a dimer.

The hydrogen bond between the dimers quickly breaks when the acetic acid is completely dissolved in water.

Other carboxylic acids have similar dimerization.

chemical characteristics

Acidity of an Acetic Acid

The hydrogen atoms in the carboxylic acid can partially ionize into protons, which leads to the acidity of the acid. Only 0.4% of the acetic acid molecules are dissociated in water, with a weak acidity of 4.8%, pKa= 4.75( 25°C), and pH of 2.4%. [6]

reaction with inorganic matter

1. A chemical reaction between some salt and another salt can produce the corresponding acetate salt.

reaction

equation for the response

Ethical acid and sodium carbonate

2CH3COOH+Na2CO3= 2CH3COONa+CO2+H2O

Acetate and calcium carbonate

2Ca+CO2+H2O=( CH3COO) 2CH3COOH+CaCO3.

acetic acid and sodium bicarbonate

NaHCO3+CH3COOH= CH3COONa+H2O+CO2.

Acetic acid reacts with weak acids.

2CH3COOH+CO32= 2CH3COO-+H2O

Barium Carbonate (BaCO₃): Properties, Production, Applications, and Safety

图片
  1. Introduction Barium Carbonate (BaCO₃) is an inorganic compound widely used in industries such as ceramics, glass, and chemicals. It is a white, odorless powder with limited solubility in water but soluble in acids. This article explores its properties, synthesis methods, applications, and safety measures in exhaustive detail. 2. Physical and Chemical Properties 2.1 Physical Properties Molecular Weight: 197.34 g/mol Appearance: White crystalline solid (rhombic or alpha form at room temperature) Density: 4.286 g/cm³ Melting Point: 811°C (decomposes to BaO + CO₂) Solubility: 0.002 g/100 mL (water, 20°C) Soluble in acids (e.g., HCl, HNO₃) 2.2 Chemical Properties Thermal Decomposition: BaCO3→ΔBaO+CO2↑ BaCO3ΔBaO+CO2↑ Reaction with Acids: BaCO3+2HCl→BaCl2+H2O+CO2↑ BaCO3+2HCl→BaCl2+H2O+CO2↑ Conversion to Barium Sulfate: BaCO3+H2SO4→BaSO4+H2O+CO2↑ BaCO3+H2SO4→BaSO4+H2O+CO2↑ 3. Production Methods 3.1 Carbonation Process Barium sulfide (BaS) solution is treated with CO₂: BaS+H2O+CO2→BaC...

Matrine  Sophora flavescens Chemical composition As early as the early 1930s, the Soviet Union began to study it abroad, and China began in 1972. The focus of research at home and abroad is on alkaloids. The alkaloids extracted, separated and identified from Sophora flavescens plants in China mainly include oxymatrine (C15H24N2O2), matrine (C15H24N2O), isomatrine (Iosmatrine, C15H24N2O), hydroxymatrine (sophor-anol), sophocarpine (C15H22N2O), N-oxysophocarpine (C15H22N2O2), sophoramine, sophoridine (Sophoridine, C15H24N2O), Aloperine, sparteine, N-methylcytisine, anagyrine, bap-iifoline, sophocarpine, d-matrine, d-isomatrine, d-oxymatrine, l-anagyrine, l-methyleytisine, l-baptifoline, kurarid-in, sophoranol (C15H24N2O2), sophoranhol N-oxide (C15H24N2O3), N-methylcytisine (C12H16N2O), and other alkaloids. Flavonoids: The flavonoids contained in Sophora flavescens are mostly dihydroflavones and dihydroflavonols, and there are also flavones, isoflavones, chalcones, etc. The flavonoids...
