মানবদেহের রক্তে কোন বাফার দ্রবণ (Buffer solution) থাকে?

Question

Accepted Answer

সঠিক উত্তর: NaHCO3 and H2CO3। ব্যাখ্যা:

Human blood contains a buffer of carbonic acid (H2CO2) and bicarbonate anion (HCO3-) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid
