Hcn is weak or strong acid
WebJan 5, 2024 · For example, ammonia, a weak base in aqueous medium, can be a rather strong base in another medium. Similarly, pure 100% dry $\ce{H2S}$ is theoretically a stronger acid than perfectly dry gaseous $\ce{HCl}$ due to a smaller bond dissociation energy and weaker dipole interaction. But, when it comes to aqueous medium, many … WebSep 1, 2024 · A strong acid is one which completely dissociates in its solvent. Under most definitions, the acid dissociates into a positively-charged hydrogen ion (proton) and a negatively-charged anion. The seven most common strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric …
