Is H2SO3 an acid, a base, or a salt? Explain. Is HF an Arrhenius acid, an Arrhenius base, or neither? Explain. What is an acid/base reaction? In an acid/base reaction will there always be an acid and always be a base? Is Ca(OH)2 an Arrhenius acid, an Arrhenius base, or neith...
On the flip side, a 0.0005 M HCl solution is dilute, yet still strong. Conjugate acid is an acid that formed when the parent base compound gains one proton and the conjugate base is a base that formed when the parent acid compound loses one proton. Is NO2 a weak conjugate base? Expert...
Which of the following is NOT an acid conjugate base pair? A. NH4+/NH3 B. H3O+/OH- C. H2SO3/HSO3- D. C2H3O2-/HC2H3O2 E. All of the above are conjugate acid-base pairs. What is the conjugate base of carbonic acid, H2...
落到地面 Natural facture The acid rain can produce the sulfuric acid, in the acid rain sulphur dioxide (SO2) responded with the atmospheric in water that, the production sulfurous acid (H2SO3), the sulfurous acid also responded with the atmospheric in oxygen, the production sulfuric acid (H2SO...
What is the basicity of H2SO3? Which of the following is a weak acid? a. HCl b. HNO_{3} c. H_{2}SO_{4} d. HBr e. H_{2}CO_{3} Identify the most acidic proton in each of the following compounds: What is the ...
Unlike sulphuric acid (H2SO4), sulphurous acid (H2SO3) isa weak acid; that is, aqueous sulphurous acid acid does not dissociate entirely into H+ (H3O+) and bisulfite ions, meaning that the bisulfite ion is comparatively stronger in maintaining a proton when there is a base, such as water...
The correct Answer is:A To determine which compound is Caro's acid, we need to analyze the given options: H2SO5, H2SO8, H2SO3, and H2S2O3. 1. Identify the Name of Caro's Acid: - Caro's acid is known as peroxy monosulfuric acid. 2. Check the Chemical Formula: - The chemical...
The condensate acts as a source of H2SO3 and H2SO4 or their acid salts, and is used in a quantity corresp. with the amt. of residual hypochlorite and undissolved Mg cpds. in the pulp. The invention eliminates the need for the separate treatment of waste bleach water.DRASEN,EDMUND,DIPL....
Sulfurous acid(H2SO3), is a weak diprotic acid (pKa,1=1.89 and pKa,2=7.21 at 25oC). What is the pH of 0.109 mol/L H2SO3(aq) at 25oC? The pH of a 0.129 M solution of a weak acid, HB, is 2....
