Express your answer as a chemical formula. This means that both reactions are acid-base reactions by the Brnsted-Lowry definition. Explain. It is a typical salt, forming neutral aqueous solutions. What is the conjugate acid of CH3NH2? CH3NH2 is a weak base (Kb = 5.0 * 10-4) and so the salt, CH3NH3NO3, acts as a weak acid. The conjugate acid of CH 3 NH 2 is a Methylammonium ion (CH 3 NH 3+ ). Is an aqueous solution with H3O+ = 8.69 x 10-9 M acidic, basic, or neutral? Explain. Answer Save. HNO2 + H2O NO2- + H3O+ 2. Write the ionic equation that shows why the solution is acidic or basic.
