B. add acid to water .
C. mix acid and water simultaneously .s
D. add water to acid in a shallow container .

Answer

To answer the question "The correct way of making a solution of acid in water is to", we need to follow these steps:

### Step-by-Step Solution:

1. **Understand the Process**: When making a solution, we need to mix an acid with water. However, the order in which we mix them is crucial for safety.

2. **Identify the Incorrect Method**: The first method is adding water to acid. This is dangerous because when water is added to concentrated acid, it reacts vigorously, releasing a large amount of heat. This heat can cause the glass container to break, leading to spills and potential burns.

3. **Identify the Correct Method**: The correct method is to add acid to water. When acid is added to water, the heat generated is absorbed by the water, which helps to dissipate the heat and reduces the risk of an explosion or breakage of the container.

4. **Safety Precautions**: Always add acid to water slowly and in small amounts (drop by drop) to control the reaction and heat generation.

5. **Conclusion**: Therefore, the correct way to make a solution of acid in water is to add acid to water.

### Final Answer:
The correct way of making a solution of acid in water is to **add acid to water**.
