When zinc reacts with sodium hydroxide the products formed are

Options

A. zinc hydroxide and sodium
B. sodium zincate and water
C. sodium zincate and hydrogen
D. sodium zincate and oxygen.

Explanation

To determine the products formed when zinc reacts with sodium hydroxide, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Zinc (Zn)
- Sodium hydroxide (NaOH)

### Step 2: Write the Reaction
When zinc reacts with sodium hydroxide, the reaction can be represented as:
\[ \text{Zn} + \text{NaOH} \rightarrow \text{Products} \]

### Step 3: Determine the Products
In this reaction, zinc reacts with sodium hydroxide to form:
- Sodium zincate (Na₂ZnO₂)
- Hydrogen gas (H₂)

The balanced chemical equation for this reaction is:
\[ \text{Zn} + 2\text{NaOH} \rightarrow \text{Na}_2\text{ZnO}_2 + \text{H}_2 \]

### Step 4: Conclusion
Thus, the products formed when zinc reacts with sodium hydroxide are sodium zincate and hydrogen gas.

### Final Answer
The products formed are sodium zincate (Na₂ZnO₂) and hydrogen gas (H₂).
