The addition of 5.0x10–3 total moles of Zn2+ to a 1.0 L solution of NaCN gives a solution of the complex ion [Zn(CN)4] 2– (Kf = 4.17x1019). What is the equilibrium concentration of uncomplexed Zn2+ ions if the concentration of cyanide ions at equilibrium is 0.50 M?

Concentration of = 1.9 *

Explanation:

Find the provided attachment for solution.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
