Answer

To solve the question regarding the statements about `NaH2PO2`, we will analyze each statement step by step.

### Step 1: Understanding the Composition of `NaH2PO2`
- `NaH2PO2` is the chemical formula for sodium hypophosphite. It consists of sodium (Na), hydrogen (H), phosphorus (P), and oxygen (O).

**Hint:** Break down the compound into its constituent ions to understand its properties.

### Step 2: Identifying Acidic Nature
- An acid salt is typically defined as a salt that can donate protons (H⁺ ions) in solution. To determine if `NaH2PO2` is an acid salt, we need to check for the presence of ionizable protons.

**Hint:** Look for protons that can be released as H⁺ ions when dissolved in water.

### Step 3: Ionization of `NaH2PO2`
- When `NaH2PO2` dissolves in water, it dissociates into `Na⁺` and `H2PO2⁻` ions:
\[ NaH2PO2 \rightarrow Na^+ + H2PO2^- \]

**Hint:** Write the dissociation reaction to see the resulting ions.

### Step 4: Analyzing the `H2PO2⁻` Ion
- The `H2PO2⁻` ion contains two hydrogen atoms. However, we need to determine if these hydrogens are ionizable.
- Ionizable protons are typically those bonded to electronegative atoms like oxygen. In `H2PO2⁻`, the protons are not bonded to oxygen in a way that allows them to be released as H⁺ ions.

**Hint:** Check the bonding of hydrogen atoms in the ion to see if they can be released.

### Step 5: Conclusion on Ionizable Protons
- Since the hydrogen atoms in `H2PO2⁻` do not have the ability to dissociate and release H⁺ ions, we conclude that `NaH2PO2` has no ionizable protons.

**Hint:** Summarize your findings regarding the presence or absence of ionizable protons.

### Step 6: Evaluating the Statements
- **Statement 1:** `NaH2PO2` is an acid salt. This statement is **incorrect** because it does not have ionizable protons.
- **Statement 2:** It contains no ionizable protons. This statement is **correct**.

**Hint:** Compare the conclusions drawn from your analysis to the statements provided.

### Final Answer
- Therefore, the correct answer is that Statement 1 is false, and Statement 2 is true.
