Is h2po4 excreted from kidney during acidosis?

Answer 1

No.

H2PO4- is called dihydrogen phosphate ion. It is the conjugate base of phosphoric Acid H3PO4 and the conjugate acid of monohydrogen phosphate ion HPO42-

Answer 2

Yes, during acidosis the body binds free protons (which bring about acidosis) to certain bases that cannot be reabsorbed by the kidney.

2 of these molecules that are excreted proton bound molecules are H2PO4 (Dihydrogen Phosphate) and NH4 (ammonia). By binding the protons to molecules that cannot be reabsorbed they are excreted in the urine and the pH of the body returns to normal.

To further counter acidosis the body increases reabsorption of bicarbonate ions in the proximal convoluted tubule to act as buffers - these bind to protons in the blood and neutralise them.

Answer 3

Yes, during acidosis, the kidney excretes H2PO4 (dihydrogen phosphate) to help buffer the excess acidity in the body. This process helps maintain a stable pH and prevent complications associated with acidosis.
