WebMar 1, 2024 · So, when NaC6H5O disassociates in water and releases the two ions, the Na+ won't be able to form NaOH, but the C6H5O- will form some C6H6O. This means that the anion has taken some H+ away from some water molecules in solution, meaning that H2O has had an H taken from it, leaving behind OH-. WebNH 4CN is a salt of weak acid HCN (K a=6.2×10 −10) and a weak base NH 4OH(K b=1.8× 10 −5).
