NaH2PO2. In qualitative analysis when H2S is passed through an aqueous solution of salt … Description:sodium hypophosphite CAS No. Sodium phosphinate. Sodium hypophosphite. If the acid is stronger than the base then the salt is an acidic salt and if the base is stronger than the acid then it is a basic salt. The BMED process was optimized in terms of current density, NaH2PO2 salt concentration and initial NaOH concentration of the base solution. *Please select more than one item to compare NaH 2 PO 2 … This is because (i) H2SO4 reduces HI to I2 (ii) HI is of violet colour (iii) HI gets oxidised to I2 (iv) HI changes to HIO3 . 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. Note: In John's answer the formula of the phosphorous acid is incorrect - it is generally regarded as a dibasic acid. Sodium Hypophosphite (CAS NO.7681-53-0) is used for pharmaceutical and electroless nickel plating, it is used as a strong reductant.In the method of electroless nickel plating, a durable nickel-phosphorus film can coat objects with irregular surfaces, and can widely be used ionics, aviation and the petroleum field.It also can be used as a food additive. 1.
