# H2nnh2 acid or base

A 10.0 mL Aliquot of 0.40 M Hydrazine, H2NNH2, (weak base) is titrated with a 0.20 M HCl solution (strong acid). Calculate the pH of the solution after the. In chemistry, bases are substances that, in aqueous solution, are slippery to the touch, taste astringent, change the color of indicators (e.g., turn red litmus. Get the detailed answer: The weak base hydrazine (H2NNH2) is added to pure water. If the pH of the resulting solution is 10.2, what is the. N2H4 is a weak base, as a general rule when a molecule has an amine group it will be a base. The larger the kb value the stronger the base it is. 1.10 (serine-sulfate ammonia-lyase) inhibitor. It is a conjugate base of a hydrazinium(1+). It is a conjugate acid of a hydrazinide.
