Sodium phosphate dibasic (NaH2PO4), also referred to as disodium phosphate, is a generally used phosphate salt in biochemistry research because of its versatile properties. It is a key component within the preparation of phosphate buffer saline (PBS) and phosphate buffer, a commonly used buffer resolution in many biological purposes. In addition to its buffer properties, NaH2PO4 is also used as a precipitating agent to form silver orthophosphate (Ag3PO4) powders, making it a precious instrument ...
