To simulate the pH of blood, which is 7.4, an undergraduate researcher in a biology lab produced a buffer solution by dissolving sodium dihydrogen phosphate (K_a = 6.2 * 10^-⁸) and disodium hydrogen phosphate (K_a= 3.6 *10^-¹³) together in an aqueous solution. What mole ratio of Na₂HPO₄/NaH₂PO₄ did she need to use?
