1. Let us assume that Cd(OH)2(s) is completely insoluble, which signifies that the precipitation reaction with NaOH(aq) (presented in the transition) would go to completion.
Cd2+(aq)+2NaOH(aq) â Cd(OH)2(s)+2Na+(aq)
If you had a 0.500 L solution containing 0.0230 M of Cd2+(aq), and you wished to add enough 1.34 M NaOH(aq) to precipitate all of the metal, what is the minimum amount of the NaOH(aq) solution you would need to add? Assume that the NaOH(aq) solution is the only source of OHâ(aq) for the precipitation.
Express the volume to three significant figures and include the appropriate units.
minimal volume of NaOH(aq) solution = ______________
2. What mass of a 0.358 % KCN solution contains 1190 mg of KCN?
Express the mass to three significant figures and include the appropriate units.
