Question

Find the odd one out. Give a reason for your answer.

Salt solution, milk, juice, and alcohol

Answer 1

• Salt solution is composed of common salt $\left(\mathrm{NaCl}\right)$ and water.
• Milk is composed of carbohydrates dissolved in water. These carbohydrates consist of Carbon and hydrogen
• Juice also contains organic acid, which means Carbon element in another form.
• Alcohol has a chemical formula ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$. Hence, it also contains Carbon.

Therefore, the odd one out is Salt solution.
