Explanation: Differentiate between basic and acidic salt you need to guess the acid and base from which the cation and anion of the salt are derived. 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. 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. Compare Products: Select up to 4 products. (Price VAT, 21% incl.
