50 mL of a solution of 0.0200 M Zn2+ will be titrated with 0.0100 M EDTA in 0.0100 M NH3 at pH 6.0. Ethylenediaminetetraacetic acid (EDTA) can be considered as a tetraprotic acid (H4Y). The stepwise acid dissociation constants are: K1 = 1.02 x 10-2, K2= 2.14 x 10-3, K3 = 6.92 x 10-7 and K4 = 5.50 x 10-11.

A titration using 0.200 M NaOH being added to 40.00 mL of 0.400 M H_2SO_4H2SO4 1. What volume of 0.200 M NaOH is required to observe a pink color (the endpoint of the titration)?
If a solution of 0.10 M Mn²+ and 0.10 M Cd²+ is gradually made basic, what will the concentration of Cd²+ be when Mn(OH)2 just begins to precipitate? Assume no change in the volume of the solution. For Mn(OH)2, Ksp = 1.6 × 10-13 and for Cd(OH)2, Ksp = 7.2 x 10-15; thus, Mn(OH)2 is more ◆soluble than Cd (OH) 2. [Cd²+] = M
Color change table is given.
A student does not filter his/her saturated solution before titrating. Will the calculated Ksp probably be too high, too low, or unaffected? Why? Solid substances are not part of equilibrium equations, so their presence would leave the value of Ksp unaffected. The remaining solids would absorb excess H30+ ions during the titration, making the calculated value of [OH ], and thus Ksp, too low. O The remaining solids would dissolve during the titration to give more OH¯. The calculated Ksp would therefore be too high.
