The correct Answer is:
To solve the question, we need to analyze both statements provided and determine their validity. ### Step 1: Analyze Statement 1 **Statement 1:** A salt is produced when an acid is neutralised by a base. - When an acid reacts with a base, a chemical reaction occurs that typically produces a salt and water. For example, when hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH), the products are sodium chloride (NaCl), which is a salt, and water (H2O). - Therefore, Statement 1 is **true**. ### Step 2: Analyze Statement 2 **Statement 2:** A salt can be acidic, basic or neutral. - Salts can indeed be classified based on the strength of the acid and base from which they are formed: - **Acidic salts** are formed from a strong acid and a weak base (e.g., ammonium chloride, NH4Cl). - **Basic salts** are formed from a weak acid and a strong base (e.g., sodium bicarbonate, NaHCO3). - **Neutral salts** are formed from a strong acid and a strong base (e.g., sodium chloride, NaCl). - Therefore, Statement 2 is also **true**. ### Conclusion Both statements are true, but the question asks for the correct option based on the analysis of these statements. ### Final Answer Both statements are correct, so the correct option is **Option 2**. ---
