You dissolve 3.25 g of sodium oxalate (Na_2C_2O_4) in sufficient water to produce a final solution volume of 100.0 mL. Assuming all of the solid dissolves, calculate the solution pH. You have available 1.00 L volumes of the three following solutions: 1.00 M HCl, 1.00 M NaOH and 1.00 M NaH_2PO_4. You wish to prepare 500.0 mL of a buffer solution that maintains a pH of 2.50. Indicate which two of these three solutions you would use to produce this buffer, and calculate the volume of each of these two solution you would need to mix to get the desired volume and pH value for the buffer.
