Phenol ionization
WebPhenol is acidic enough to do the first step, and so converts carbonate ions into hydrogencarbonate ions, but isn't acidic enough to do the second step. So sodium … WebPhenol is no exception - the only difference is the slow reaction because phenol is such a weak acid. Phenol is warmed in a dry tube until it is molten, and a small piece of sodium added. There is some fizzing as hydrogen gas is given off. The mixture left in the tube will …
