The correct Answer is:
To analyze the statements regarding beryllium hydroxide, we will break down the information step by step. ### Step 1: Understand the Solubility of Be(OH)₂ Beryllium hydroxide, \( \text{Be(OH)}_2 \), is known to be soluble in both hydrochloric acid (HCl) and sodium hydroxide (NaOH). - **In HCl**: When beryllium hydroxide reacts with hydrochloric acid, it forms beryllium chloride and water: \[ \text{Be(OH)}_2 + 2 \text{HCl} \rightarrow \text{BeCl}_2 + 2 \text{H}_2\text{O} \] This indicates that \( \text{Be(OH)}_2 \) dissolves in HCl. - **In NaOH**: When beryllium hydroxide reacts with sodium hydroxide, it forms sodium beryllate: \[ \text{Be(OH)}_2 + 2 \text{NaOH} \rightarrow \text{Na}_2\text{Be(OH)}_4 \] This indicates that \( \text{Be(OH)}_2 \) also dissolves in NaOH. ### Step 2: Determine the Nature of Be(OH)₂ Beryllium hydroxide is classified as an amphoteric hydroxide. Amphoteric substances can react with both acids and bases. - **Amphoteric Nature**: Since \( \text{Be(OH)}_2 \) reacts with both an acid (HCl) and a base (NaOH), it confirms its amphoteric nature. ### Step 3: Evaluate the Statements - **Statement 1**: "Be(OH)₂ is soluble both in HCl and NaOH." - This statement is **true** based on the reactions we analyzed. - **Statement 2**: "Be(OH)₂ is amphoteric in nature." - This statement is also **true**, as it can react with both acids and bases. ### Conclusion Both statements are correct, and statement 2 correctly explains statement 1. ### Final Answer Both Statement 1 and Statement 2 are correct, and Statement 2 is the correct explanation for Statement 1. ---
