Write an equation to show that hydrocyanic acid , HCN , behaves as an acid in water. **Title: Understanding the Acid Behavior of Hydrocyanic Acid (HCN) in Water****Equation Context:**To demonstrate how hydrocyanic acid (HCN) acts as an acid when dissolved in water, we need to understand the basic reaction that occurs. Acids are substances that donate protons (H⁺ ions) to other entities. **Chemical Equation:**\[ \text{HCN} + \text{H}_2\text{O} \leftrightarrows \text{H}_3\text{O}^+ + \text{CN}^- \]**Explanation:**1. **Reactants:** - **HCN:** Hydrocyanic acid, the acid in this reaction. - **H₂O:** Water, which acts as the base.2. **Products:** - **H₃O⁺ (Hydronium Ion):** Forms when HCN donates a proton (H⁺) to the water molecule. - **CN⁻ (Cyanide Ion):** The conjugate base of HCN after losing a proton.**Conceptual Understanding:**In an aqueous solution, HCN donates a proton to the water. This proton transfer leads to the formation of the hydronium ion (H₃O⁺), which is indicative of the acidic nature of a solution, and the cyanide ion (CN⁻), demonstrating the acid's dissociation. This reaction is reversible and the equilibrium lies towards the reactants, indicating that HCN is a weak acid.
