List of top Chemistry Questions on Acid Dissociation Constants

Identify the compound which shows mass spectrum: $m/z = 60$ (100%), $m/z = 61$ (3%), $m/z = 62$ (0.2%)

Arrange the dissociation constant of phosphoric acid in increasing order. \[\begin{aligned} \text{H}_3\text{PO}_4 + \text{H}_2\text{O} &\rightleftharpoons \text{H}_3\text{O}^+ + \text{H}_2\text{PO}_4^- \quad (K_{\text{a1}}) \\ \text{H}_2\text{PO}_4^- + \text{H}_2\text{O} &\rightleftharpoons \text{H}_3\text{O}^+ + \text{HPO}_4^{2-} \quad (K_{\text{a2}}) \\ \text{HPO}_4^{2-} + \text{H}_2\text{O} &\rightleftharpoons \text{H}_3\text{O}^+ + \text{PO}_4^{3-} \quad (K_{\text{a3}}) \\ \end{aligned}\]
