Question : During dehydration what is the substance that is usually lost by the body ?
Option 1: Sugar
Option 2: Sodium chloride
Option 3: Calcium phosphate
Option 4: Potassium chloride
Correct Answer: Sodium chloride
Solution : The correct option is sodium chloride.
During dehydration, the substance that is commonly lost by the body is sodium ions (Na+) along with chloride ions (Cl-). Together, they create sodium chloride. When a person becomes dehydrated, they frequently lose not just water but also important electrolytes such as sodium chloride through processes such as sweating, vomiting, diarrhoea, or insufficient fluid intake. Maintaining adequate electrolyte balance is critical for many biological activities, including nerve transmission, muscular contraction, and fluid balance. Dehydration can cause an imbalance in these electrolytes, which can be harmful to health.
