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...
