calculate the mass of solid needed to make the solution. Explain the steps you took in making each solution and in verifying that it has the correct concentration.
12. 100 ml of solution that is 1.0 M in sodium cation, using sodium chloride.
13. 100 ml of a solution that is 0.7 M in chloride anion, using magnesium chloride (MgCl2).
14. 250 ml of a solution that is 0.34 M in sodium cation, using sodium sulfate decahydrate (Na2SO4, 10H2O).
15. 500 ml of a solution that is 0.25 M in sulfate anion, using sodium sulfate decahydrate.
16. You have three bottles, one filled with 1M NaAc (Sodium Acetate), one filled with 1M HAc (Acetic Acid), and one filled with distilled water. You need to create a buffer solution that has a pH of 4.75 such that when 1ml of 10M HCl is added to 100ml of your buffer, the resulting pH is 3.75 (±0.1). What concentrations of HAc and NaAc do you need to create the buffer solution?
thanks for everone help me
