Mar 28, 2025 · Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H 3 O +) and hydrogen sulfate ions (HSO 4−). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO 42−).

Exposure to moist air or water. Incompatible Materials Strong oxidizing agents, Combustible material, Bases, Organic materials, Reducing Agent, Finely powdered metals, Peroxides

Sulfuric acid is a colorless oily liquid. It is soluble in water with release of heat. It is corrosive to metals and tissue. It will char wood and most other organic matter on contact, but is unlikely to cause a fire. Density 15 lb / gal.

Mar 15, 2020 · H2SO4 + H2O = HSO4- + H3O+. 这个反应是完全进行的，几乎不可逆。 虽然按中学认为硫酸是二元强酸，但实际上硫酸的第二级电离不完全，所以在这里就不写高中学的两个氢离子那个反应了，我们也不用管硫酸根离子的存在，它也只占少数。 强酸的溶液中，水的主要反应有两种，第一是和酸的分子反应，第二则是参与溶剂化，使各种离子更加稳定。 稀硫酸中，水 …

solvent: Sulphuric acid aqueous solution; The reaction enthalpy relies on -10.6 kJ/mol for the enthalpy of solution of EtOH (l) and on 9.97±0.04 for the enthalpy of solution of Na2SO4 (cr) Blanchard, Joly, et al., 1974. A value of -490.8 ± 5.9 kJ/mol was derived in Blanchard, Joly, et al., 1974 for the enthalpy of formation.

Jun 17, 2021 · In spite of the viscosity of the acid, the effective conductivities of the $\ce{H3SO4+}$ and $\ce{HSO4-}$ ions are high due to an intramolecular proton-switch mechanism (analogous to the Grotthuss mechanism in water), making sulfuric acid a good conductor of electricity.

Jan 20, 2017 · Full name of H3SO4 is protonated sulfuric acid. Explanation: 1. Protonation is also known as hydration. It is a method in which a proton is added to an ion, atom or a molecule so as to form a conjugate acid. On the other hand, the method in which a proton is removed from an ion or a atom or a molecule, the process is called deprotonation. 2.

SO3能够进攻苯环，发生磺化反应，最终生成苯磺酸（C6H5—SO3H），高中有机化学中会学到。 在苯被浓硫酸磺化的磺化反应中，真正的主要磺化剂包括三氧化硫SO3、质子化的硫酸分子H3SO4+等，浓硫酸中的SO3和H3SO4+正是通过上述反应生成的。 首先你提问的题干就是错的，浓硫酸会脱掉浓硫酸里的水。 自然选择号，前进四！ 先问是不是，再问为什么！ 极浓的硫 …
