Moist ethylene can be dried by passing it through concentrated suphuric acid.

Explanation

To determine whether the statement "Moist ethylene can be dried by passing it through concentrated sulfuric acid" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ethylene**: Ethylene is a simple alkene with the formula \( \text{C}_2\text{H}_4 \) or \( \text{CH}_2=CH_2 \). It is a gaseous hydrocarbon that can be present in a moist form, meaning it contains water vapor.

2. **Role of Concentrated Sulfuric Acid**: Concentrated sulfuric acid (\( \text{H}_2\text{SO}_4 \)) is a strong dehydrating agent and is often used to remove water from substances. However, it can also react with certain compounds.
