Witryna25 kwi 2024 · Certainly, the pKa's of water and ethanol are similar. Although the solubility of KCN in ethanol is less than water, I suspect that the greater solubility of benzyl chloride in ethanol is the determining factor. If benzyl alcohol is formed in aqueous KCN, might a solvolysis (SN1) be competing? Food for thought. $\endgroup$ – WitrynaNaCN and KCN (solids) are mainly used in silver and gold mining and in electroplating. All of these forms of cyanide are soluble in water.
