Granulated zinc is obtained by

Options

A. Suddently cooling molten zinc
B. Adding molten zinc to water
C. Heating zinc to `150^@ C`
D. Dropping molten zinc drop by drop

Answer

To obtain granulated zinc, the following steps can be followed:

1. **Understanding Granulated Zinc**: Granulated zinc is a form of zinc that has a larger surface area due to its smaller particle size. It is commonly used in laboratory settings, particularly for the preparation of hydrogen gas.

2. **Preparation Method**: The method to produce granulated zinc involves the use of molten zinc.

3. **Adding Molten Zinc to Water**: The key step in the process is to take molten zinc and add it to water drop by drop. This should be done carefully to ensure that the zinc reacts properly with the water.

4. **Reaction with Water**: When molten zinc is introduced to water, it reacts with the water and breaks down into smaller particles. This reaction leads to the formation of granulated zinc.

5. **Final Product**: The end result of this process is granulated zinc, which has a high surface area and is suitable for various applications, including the preparation of hydrogen.

Thus, granulated zinc is obtained by adding molten zinc to water drop by drop.
