3. If you didn't have a pH meter, how would you make 1.00 L of 40.0 mM potassium phosphate buffer at pH 6.96, given ONLY potassium phosphate monobasic (KH₂PO4) and potassium phosphate dibasic (K₂HPO4)? These are the only two chemical available -no strong acid or base are needed. Include details such as masses and when/how you would bring the volume up to 1L. Show your calculations. Use pka2=7.20 for phosphoric acid.
