Psilocybin is a natural product of psychotropic "magic" mushrooms and has the Following structure: HO HO O=0 Psilocybin The pK a Of the first phosphate oxygen is 1.3, the pK. Of the second phosphate oxygen is 6.2, And the pKa Of the tertiary amine is 10.4. What is the average charge of psilocybin when Dissolved in your carbonic acid buffer of pH=6?

Highlight your values of A,B,C and D.  For your question: A mL of B mol/L sodium phosphate solution is combined with C mL of  D mol/L calcium bicarbonate.  (Calcium bicarbonate is soluble.) A       mL B      mol/L C       mL D      mol/L 75.0 ml 0.300 67.5 0.350   Before you begin your reaction, you must accurately produce 1.500 L of your sodium phosphate solution from sodium phosphate trihydrate solid.  Write out a procedure to explain all the steps you will take in the lab when making the solution to ensure that your solution concentration is accurate.  Please include calculations that show the required mass of solid.  Also include the correct names of all equipment used.
