Sodium hypophosphite. phosphinic acid). Start Now! Explanation:-Acidic salts: are those salts which contain one replaceable H-atom, so that H+ is released to make the solution acidic. Сoding to search: P4 + 3 NaOH + 3 H2O = PH3 + 3 NaH2PO2. The pH in a solution of a salt of H₂PO₄⁻ is the average of pKa₁ and pKa₂: pH = (2.12 + 7.21)/2 = 4.66 (See the link below for a proof of this in class notes at the left of the page: slides11.pdf) So, since the pH is less than 7, the solution is acidic. Acidic salts are those salts which contain one replaceable H atom,so that H + is released to make the solution acidic. It’s chemical formula is NaH2PO2.H2O and molecular weight is 105.99.
