It is also a Lewis acid, because it is accepting a pair of electrons to form the O-H bond in hydronium ion. H2S has two lone pairs on the S, so it can also act as a Lewis base. In the presence of a strong acid like H2SO4, the H2S becomes protonated.

WebHydrogen sulfide is a weak acid whose first hydrogen ion is lost according to the following reaction: 0.23 mol of HI is added to 1.0 L of a 1.2 M NH3 solution. Indicate which species will act as an acid, which species will act as a base, and which species will act as neither an acid nor a base (if any). Keep in mind that NH3 is a weak base. WebAug 14, 2024 · The larger the Ka, the stronger the acid and the higher the H + concentration at equilibrium. Like all equilibrium constants, acid–base ionization constants are actually measured in terms of the activities of H + or OH −, thus making them unitless. The values of Ka for a number of common acids are given in Table 16.4.1.
