Latin name for royal water is X. It is a mixture of Y and Z in the ratio 3: 1. Some of the properties of X are different from Y and Z. What are X, Y and Z respectively?

Options

A. Aqua regia, `HCl, HNO_(3)`
B. Aqua regia, `HNO_(3), HCl`
C. `H_(2)SO_(4), H_(2)O,SO_(2)`
D. `H_(2)SO_(4),H_(2)S, SO_(3)`

Explanation

To solve the question, we need to identify the substances represented by X, Y, and Z based on the clues provided.

### Step-by-Step Solution:

1. **Identify X (Royal Water)**:
- The question states that the Latin name for royal water is X. The term "royal water" is commonly known as "aqua regia."
- Therefore, we conclude that **X = Aqua Regia**.

2. **Identify Y and Z**:
- The problem mentions that aqua regia (X) is a mixture of Y and Z in the ratio of 3:1.
- Aqua regia is made by mixing concentrated hydrochloric acid (HCl) and concentrated nitric acid (HNO3).
- In this mixture, the ratio of HCl to HNO3 is 3:1.
- Hence, we can assign:
- **Y = HCl (Hydrochloric Acid)**
- **Z = HNO3 (Nitric Acid)**

3. **Summarize the Findings**:
- We have identified:
- **X = Aqua Regia**
- **Y = Hydrochloric Acid (HCl)**
- **Z = Nitric Acid (HNO3)**

### Final Answer:
- X = Aqua Regia
- Y = Hydrochloric Acid (HCl)
- Z = Nitric Acid (HNO3)
