Solutions of bisulfite are typically prepared by treatment of sulfur dioxide with aqueous base: [3] 3 is the conjugate base of sulfurous acid, (H 2 SO 3). 3 is a weak acidic species with a p Ka of 6.97. Its conjugate base is sulfite, SO2−. Because of this equilibrium, anhydrous sodium and potassium salts of bisulfite cannot be obtained.

2021年10月14日 · Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray.. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. If it can be done safely, move undamaged containers away from the area around the fire.

For the HSO3- structure use the periodic table to find the total number of valence electrons for the HSO3- molecule. Once we know how many valence electrons there are in HSO3- we can distribute...

Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO2 molecule and the bisulfite ion, HSO− 3. [2] . The intensities of the signals are consistent with the following equilibrium: SO2 + H2O ⇌ HSO− 3 + H+ Ka = 1.54 × 10 −2; p Ka = 1.81.

HSO3{-} + H{+} = H2O + SO2 is a Double Displacement (Metathesis) reaction where one mole of Bisulfite Ion [HSO 3-] and one mole of Deuteron [H +] react to form one mole of Water [H 2 O] and one mole of Sulfur Dioxide [SO 2]

2016年2月28日 · I think HSO3 acts as a base because it donates a pair of electrons and this is another definition when you think of acids and bases. An acid is a substance that accepts a pair of electrons whereas a base is a substance that donates a pair of electrons.

The hydrogen sulfite, or bisulfite, ion is the ion HSO3-. It is the conjugate base of sulfurous acid, H2SO3. Bisulfite has long been recognized as a reagent to react with organic compounds in various ways; prominent among them are additions to carbonyl groups and to carbon-carbon double bonds, and free radical reactions in the presence of oxygen.

2004年4月18日 · I don't know about HSO3- and H2SO3, but if you mean HSO4 and H2SO4, then the latter is stronger. Increased electronegativity doesn't translate to stronger bonds. Of your list, HCl is the strongest acid, followed by acetic acid, ammonia, and sodium hydroxide.

Bisulfite is a key player in the nucleophilic addition of water to carbonyl compounds, such as aldehydes and ketones. In this process, the nucleophilic bisulfite ion (HSO3-) attacks the electrophilic carbon of the carbonyl group, forming a tetrahedral bisulfite addition product.
