پرسش‌هایی که معلم‌ها می‌پرسند

Can a blue Benedict’s tube without heating prove that reducing sugar is absent?

No. Complete the heated test first. A positive result forms an orange-red precipitate; iodine turns blue-black for starch, Biuret violet for protein, and lipids form a cloudy white emulsion.
