The correct Answer is:
To analyze the statements regarding sodium hypophosphite (NaH₂PO₂), let's break down the information step by step. ### Step 1: Understanding the Structure of NaH₂PO₂ - Sodium hypophosphite has the formula NaH₂PO₂. - It contains two hydrogen atoms attached to phosphorus (P). - The structure can be represented as Na⁺ + H₂PO₂⁻, where H₂PO₂⁻ is the hypophosphite ion. **Hint:** Look at the structure of the compound to identify the positions of hydrogen atoms. ### Step 2: Identifying the Nature of the Hydrogen Atoms - The two hydrogen atoms in NaH₂PO₂ are bonded to phosphorus. - These hydrogen atoms are not ionizable in the same way that hydrogen atoms in acids (like HCl) are. **Hint:** Consider how hydrogen atoms can be classified based on their ability to donate protons (H⁺). ### Step 3: Determining if NaH₂PO₂ is an Acid Salt - An acid salt typically contains hydrogen atoms that can dissociate to produce H⁺ ions. - Since the hydrogen atoms in NaH₂PO₂ are not ionizable, NaH₂PO₂ does not qualify as an acid salt. **Hint:** Recall the definition of acid salts and compare it with the properties of NaH₂PO₂. ### Step 4: Evaluating the Statements - **Statement 1:** "Although NaH₂PO₂ contains two H-atoms, it is not an acid salt." This statement is true because the hydrogen atoms are not ionizable. - **Statement 2:** "It contains two ionizable hydrogens." This statement is false because the hydrogen atoms attached to phosphorus are not ionizable. **Hint:** Cross-check the definitions of acid salts and ionizable hydrogens to confirm the truth of each statement. ### Conclusion - Statement 1 is true. - Statement 2 is false. Thus, the correct conclusion is that Statement 1 is true and Statement 2 is false. ### Final Answer - Statement 1: True - Statement 2: False
