Simply exchange a proton, H^+, and conserve mass and charge. See this answer; and also see this answer, and also see this answer. Do not be intimidated by this sort of question. All we are doing is taking the starting formula, HX, H_2SO_4, HNO_3, or even HCO_3^-, and removing a proton, H^+, to form the conjugate bases, X^-, HSO_4^-, NO_3^-, and CO_3^(2-) . As with all such chemical reactions The University of Waterloo science page lists HSO4 as the conjugate base of H2SO4. H2SO4 is the chemical name for sulfuric acid, and the conjugate base is hydrogen sulfate. Even though HSO4 is also an acid, it can either be a conjugate acid or a conjugate base depending on context. The conjugate base of a moderately weak acid is a moderately weak base. Weak Acid - Strong Conjugate Base Pair. A weak Brønsted-Lowry acid has very little tendency to donate a proton. Weak Brønsted-Lowry acids include H 2 O 2, CH 3 OH and H 2 O. For example, methanol is a weak Brønsted-Lowry acid: acid + base H2SO4 (sulphuric acid) will donate an H+ ion in the solution to form H3O+ (hydronium). The remaining HSO4 would be the conjugate base formed. Now, for your question, The sulfate ion ( SO4 2− ) is the conjugate base of HSO−4 . Reason : Even if it h... The use of conjugate acid-base pairs allows us to make a very simple statement about relative strengths of acids and bases. The stronger an acid, the weaker its conjugate base, and, conversely, the stronger a base, the weaker its conjugate acid.. TABLE \(\PageIndex{1}\):Important Conjugate Acid-Base Pairs.. Table \(\PageIndex{1}\) gives a list of some of the more important conjugate acid-base Write the formula of the conjugate base for the following acids: Acid Conjugate base (a) HNO2 (b) H2SO4 (c) H2S (d) HCN (e) HCOOH - 14731094 A conjugate base contains one less H atom and one more - charge than the acid that formed it. Let us take the example of bicarbonate ions reacting with water to create carbonic acid and hydronium ions. HCO₃⁻ + H₂O → H₂CO₃ + OH⁻ base + acid → Conj A + Conj B We see that HCO₃⁻ becomes H₂CO₃. H2SO4. yes. strong base trend ? Lithium-cesium calcium-barium. In general, an anion that is the conjugate base of a weak acid reacts with water to produce. hydroxide ion. when the cation of a salt is the conjugate acid of a weak base, a solution of the salt will be. acidic. 10) Determine the acid, base, conjugate acid and conjugate base in the following reactions a) H2O + H2SO4 → H30*1 + HSO41 b) NH3 + H2CO3 + + NH4+1 CA HCO3 CB c) H2PO.+ + HCO3+ + HPO 2 + H2CO: + HC5H50,2 d) HPOA2 + H2C6H30,1 + H2PO4 ACA 1. Write the formula of H2SO4 conjugate base. 2. Write the formula of HPO4^2- conjugate base. 3. Write the formula of CH4 conjugate base. 4. Write the formula of CH3NH3^+ conjugate base. please please help if you can also tell me if they are a strong base, a weak base, or a species with negligible basicity would be great. ' for both the conjugate base and the original
