In this example with NH4Cl, the conjugate acids and bases are NH4+ and Cl-. Notice how also the way the formula is written will help you identify the conjugate acids and bases (acids come first on the left, bases on the right) ( 4 votes) Mike 6 years ago

Did you know?
WebSulfuric acid has two pKa values, one, each for the following equilibria: H2SO4 = HSO4 (1-) + H+ pKa = -3.00 HSO4 (1-) = SO4 (2-) + H+ pKa =1.92 Phosphoric acid has three pKa … WebYour laboratory is out of materials to make phosphate buffer and you are considering using sulfate to make a buffer instead. The pKa values for the two hydrogens in H2SO4 are -10 and 2. (a) Will this approach work for making a buffer effective near pH 7? (b) Around what pH might a sulfate-based buffer be useful?

WebHigher the oxidation state, the acidic character will be high. So, the expected order is H3P O4 > H3P O3 > H3P O2. But the actual order is : H3P O2 > H3P O3 > H3P O4. This can be explained based on the number of OH−, groups attached to the central P-atom. With an increasing number of OH− groups on the central P-atom, the acidic strength ...
WebMar 7, 2024 · Diprotic Acids. Diprotic acids contain two ionizable hydrogen atoms per molecule; ionization of such acids occurs in two steps. The first ionization always takes place to a greater extent than the second ionization. For example, sulfuric acid, a strong acid, ionizes as follows: Sulfuric acid is produced from sulfur, oxygen and water via the conventional contact process (DCDA) or the wet sulfuric acid process (WSA). In the first step, sulfur is burned to produce sulfur dioxide. S(s) + O2 → SO2 The sulfur dioxide is oxidized to sulfur trioxide by oxygen in the presence of a vanadium(V) oxide
WebApr 26, 2015 · It's not wrong to talk about the first and second pKa's of H2SO4 , but having the ability to talk about the pKa of a specific Hydrogen can make communication more clear. In other words, the chemistry doesn't change between the two sets of terminology, but …
