WebTo determine whether phosphate supplementation, started soon after birth in adequate quantity, would prevent rickets in very low birth weight infants with prenatal deficiency of phosphate, 40 neonates were given an initial dose of 50 mg/day of phosphate administered as a mixture of 189 g of sodium phosphate dibasic (disodium hydrogen phosphate ... WebJan 6, 2016 · Explanation: H 3P O4 +H 2O → H 2P O− 4 + H 3O+ Ka1 = 7.25 ×10−3. H 2P O− 4 + H 2O → H P O2− 4 + H 3O+ Ka2 = 6.31 ×10−8. H P O2− 4 +H 2O → P O3− 4 +H 3O+ Ka3 = 4.8 × 10−13. I assume the one you want is for potassium dihydrogen phosphate, K+ −OP ( = O)(OH)2, i.e. H 2P O2− 4. pKa2 = 7.20. See this link for a discussion ... desk and chair set for teens
