Question

Problem broken down into 4 individual questions.

Part 1 of 4:

Supply the calculated molarities of the indicated species in the solution mixtures.Assume the solutions are at 25 degrees Celsius.

Problem #C1: Calculate the Molarities for: HC₂H₃O₂ , C₂H₃O₂^-, H⁺

Given the following procedure (straight from lab book).

C. pH of Buffer Solutions:
1. Preparation of Buffer Solution: Weigh 3.3 g of solid sodium acetate trihydrate, NaC₂H₃O₂ * 3H₂O, into a clean 150 or 250 mL beaker. Using graduated cylinders, add 46 mL of deionized water and 4.0 mL of 6.0 M HC2H3O2. Mix thoroughly. Measure 19.0 mL of this into each of two clean beakers. Label as "A" and "B". Measure the pH of this buffer solution using the remaining 10 mL.
