Question

Note:
Consider the reaction between Fe3+ and NCS ions. The equilibrium constant for this
reaction is 620.4. Calculate the equilibrium concentration of NCS ion in a solution that
contains 10.0mL of 0.05 M ferric nitrate in 1M HNO3, 2.0mL of 5.0*10-4 M NaNCS, and
8.0mL of distilled water. Assume that all the NCS is converted to FeNCS2+.
ㄷ
(A) 6.07x10-8 M
(B) 3.04x10M
(C) OM
(D) 1.00x10
E​
