Astandard solution of fescn2 is prepared by combining 9.0 ml of 0.20 m fe(no3)3 with 1.0 ml of 0.0020 m kscn. the standard solution had an absorbance of 0.510. a trial solution was made in a similar manner, but with a more dilute fe(no3)3 reagent. the initial scn– concentration (immediately after mixing) was 0.00080 m. this trial solution had absorbance of 0.240. what is the equilibrium concentration of scn– in the trial solution?
