Refractometer used for-------:

A ) Protein

B ) Fats

C ) Vitamin

D ) Sugar ✅


Explanation:

Refractometer is used for 👉 measuring the refractive index of a substance.

Refractometer is used for measuring 👉 sugar content in a solution, especially in liquids like fruit juice, honey, or soft drinks.

This is done by measuring the refractive index, which changes based on how much sugar is dissolved.

A refractometer is an optical instrument used to measure the refractive index of liquids or solids, which helps determine concentration, purity, or composition.

📌 Key Uses:

  • Determine sugar content (e.g., in fruit juice, honey)
  • Check salinity (e.g., in aquariums or seawater)
  • Measure concentration of solutions (e.g., in chemical labs)
  • Test urine specific gravity (in medical diagnostics
  • The sugar content is often expressed in °Brix (degrees Brix), which indicates grams of sugar per 100 grams of solution.
