Lаbel аs Q-Bаse оn yоur paper. (10 min.) Yоu must show all your work for this problem on your paper. You must show starting variables, starting equations, and use one step equation dimensional analysis where applicable. In addition to showing you work on paper, you must state you final answer(s) here with units. Failure to do so will result in zero credit regardless of your work on paper. Hydroxylamine, HONH2, is a weak base that exhibits little dissociation. for this weak base, the Kb is 9.10 × 10–9. What is the pH of a 0.350 M HONH2 solution and what are the equilibrium concentrations of all reactants and products? You must use an ice chart. Please use the test of a weak base to prove your assumptions were valid. HONH2 (aq) + H2O (l) ↔ HONH3+ (aq) + OH- (aq)
