Hcn is weak or strong acid

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 … WebDec 30, 2024 · HCOOH is a weak acid. Because it contains fewer hydrogen ions in the aqueous solution since it only dissociates partially or is not 100% ionized when dissolved in water. The K a value for formic acid is 1.8 × 10-4 which is way lower than recommended value for a strong acid (K a > 1), hence, HCOOH is a weak acid. Did you like it? 0
