Ringer solution contains.

Options

A. iodine and salt
B. Acetic acid and wax
C. sodium and potassium ions
D. water and acid fuchsine

Answer

**Step-by-Step Solution:**

1. **Understanding Ringer's Solution**: Ringer's solution is a type of isotonic solution that is used in biological and medical contexts. It is designed to mimic the composition of bodily fluids.

2. **Components of Ringer's Solution**: The primary components of Ringer's solution include various salts dissolved in water. These salts are essential for maintaining osmotic balance and providing necessary ions for cellular functions.

3. **Identifying Key Ions**: The main ions present in Ringer's solution are sodium ions (Na⁺) and potassium ions (K⁺). Additionally, it contains calcium ions (Ca²⁺) and bicarbonate ions (HCO₃⁻).

4. **Analyzing the Options**: The options provided are:
- Iodine and salt
- Acetic acid and wax
- Sodium and potassium ions
- Water and acetic fixin

5. **Selecting the Correct Option**: Among the options, the one that accurately represents the components of Ringer's solution is "sodium and potassium ions." The other options do not correctly describe the contents of Ringer's solution.

6. **Conclusion**: Therefore, the correct answer to the question "Ringer's solution contains" is sodium and potassium ions.
