ज्या सामूल्य (pH) ला प्रथिण कलिळांवर असलेला भार विरुद्ध होतो त्याला ____________ असे म्हणतात. / The pH at which the charge on protein colloid is reversed is called
1)गोठण बिंदू / Coagulation Point
2)उर्णन बिंदू / Flocculation Point
3)उदासीन सामु (pH) बिंदू / Neutral pH Point
4)समविद्युत् बिंदू / Isoelectric Point✓ Correct
The pH at which the net charge on a protein colloid or amino acid is zero and the electrophoretic movement is zero is called the Isoelectric point.
