Marcella Season 3 Episode 6 Recap, Now, as NaOH is a strong base and CH3COOH is a weak acid, the resultant solution is basic in nature. Why is the compound 3,4-dihydroxy-3-cyclobutene-1,2-dione more acidic than acetic acid? The Ka for NH4+ can be found by Kw/(Kb for NH3) and the Kb for NO2- can be found by Kw/(Ka for HNO2). Ka(HCN) =6.2 x C6H5NH3+, conjugate base is a weak base, therefore it is potentially acidic NO2-, conjugate acid is a weak acid, therefore the salt is also potentially basic However, since the Ka > Kb, the solution must be acidic So it has both nature acidic on basic in its constituent, it will act as a neutral soul. My sister asked me what acids and bases are, this is what I told her. 97% of Numerade students report better grades. Add 4.0 mL of ether to the tube and cap it.
