The Correct Answer and Explanation is : 1. pH Calculations a. 0.100 M HONH2 (Kb = 1.1 x 10^-8) HONH2 (Hydroxylamine) is a weak base. To calculate the pH, we need to first calculate the pOH using the Kb value. The equation for the dissociation of HONH2 in water is: [HONH2 + H2O \rightleftharpoons HONH3^+ […]
