What are the expected products of hydrolysis of lactose ?

Explanation

To determine the expected products of the hydrolysis of lactose, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Lactose**:
- Lactose is a disaccharide composed of two monosaccharides: glucose and galactose. Its chemical formula is C12H22O11.

2. **Understand Hydrolysis**:
- Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule using water. In the case of lactose, this involves the cleavage of the glycosidic bond between glucose and galactose.

3. **Reaction with Water**:
- When lactose undergoes hydrolysis, it reacts with water (H2O). The water molecule provides a hydrogen ion (H⁺) and a hydroxide ion (OH⁻) which are used to break the glycosidic bond.

4. **Products of Hydrolysis**:
- The hydrolysis of lactose results in the formation of two monosaccharides:
- **Galactose**: One of the products formed after the hydrolysis.
- **Glucose**: The second product formed after the hydrolysis.

5. **Final Result**:
- Therefore, the expected products of the hydrolysis of lactose are **galactose and glucose**.

### Summary of Products:
- **Galactose**
- **Glucose**
