CAN YOU PLEASE PROVIDE A STEP BY STEP SOLUTION? thank you Questions - Calculate what the concentration of [H2PO4-] (weak acid) and [HPO42-] (the conjugate base) should be in the phosphate buffer to meet these requirements. - Calculate the number of moles of the two buffer components required. - Calculate the exact mL of the weak acid required to create your buffer (D1) Information given Prepare 100 mL of a phosphate buffer: With a pH of 7.45 whose pH will drop by only 0.2 pH units when 0.020 moles of H3O+ are added to 1.0 L of the buffer In the lab you will be provided with stock solutions of 0.50 M H2PO4- and 1.0 M NaOH with which to prepare your phosphate buffer. (The NaOH is used to prepare the conjugate base HPO42- from its weak acid H2PO4-)
