The dioxouranium(vi) cation (urany1,uo2)can be seperated and identified using the procedure described in the experiment. the spot test results for this cation with the with the following test reagents are k4fe(cn)6 red-brown
kscn no reaction,dmg/nh3 pale yellow
a: based on these data what would be the best test reagent for uo2
b:the R1 value of uo2 in the solvent system used in this module is 0.68. explain which of the other cation tests used in this expirment it would interfere with,what alternate tesr reaget you would therefore use to identify that other cation and which of the two tests should be performed first
The heat effect of the neutralization reaction NaOH(aq) + HCl(aq) is measured in an open adiabatic solution calorimeter (not a coffee cup calorimeter) The heat capacity of the calorimeter itself is 456 J/K.
