Iron(II) nitrate and hydrocyanic acid react to form the hexacyanoferrate(II) ion, [Fe(CN)6] -4 (aq), with a formation constant of 1.438x1035 . This complex ion has an intense blue color in solution
. a. If you add 182.734g of iron(II) nitrate solid to 750.0mL of 0.8324M CN-1 (aq) solution, what is the concentration of CN-1 (aq) still in solution when the reaction reaches equilibrium?
b. Copper(II) also forms a complex ion with cyanide ions, tetracyanocuprate(II) ion, [Cu(CN)4] -2 (aq), with a formation constant of 1.028x1025 . This complex ion has an intense green color in solution. If 10.0mL of 0.500M Cu+2(aq) and 10.0mL of 0.500M Fe+2(aq) are both added to 500.0mL of 20.0mL of CN-1 (aq), explain what you would expect to see.

Consider the following equilibrium: ⇌ Fe[CN]63−(aq) + 6H2O(l) John was trying to prepare his famous tye-dyed t-shirts. He knows that he can control the cyanide concentration in solution by using the complex ion and his knowledge of equilibrium. To get the most intense colors, he needs more cyanide in solution. The equilibrium above is exothermic as written. Explain whether John should make his shirts in hot or cold water. Explain why controlling the pH of the solution would help/hurt John’s...
