A stock solution of Na_2S_2O_3 is prepared by adding 20.40 grams of solid Na_2S_2 O_3 to enough water to make 250.0 ml of solution. A 25.0 ml sample of that stock solution is then diluted to a final volume of 500.0 ml. What is the concentration of sodium ions in the resulting solution (in mol/L)?
A solution of 50.0 mL of 0.045 M Ca(NO,), is prepared. What volume (in mL) of 1.90 M NaOH must be added to the calcium nitrate solution to begin to precipitate solid Ca(OH), from the solution? K = 6.5 x 10 Hint: Solid Ca(OH), will begin to precipitate at the point where an equilibrium exists between the solid and aqueous ions. The volume of NaOH required, will be very small so you don't have to consider the dilution of the...
