Na⁺ and Cu²⁺ Ion Calculations in 20ppm SO₄^2- Solutions

Notes:

• An additional 2-3 mL H₂O was added to each solution to aid the dissolving of the PVOH
• Heat was reduced when solutions began to boil too rapidly
• While transferring solutions to Teflon dishes, loss of sample within the small beakers (sample loss = incomplete sample transfer)
