a scientist adds a solution of bromine in an organic solvent to two test tubes. the scientist adds aqueous sodium chloride to one test tube, and aqueous sodium iodide to the other test tube.
the student shakes the mixtures, allows then to settle and records the colour of the organic layer in each mixture.
results:
SODIUM HALIDE AND COLOUR OF ORGANIC LAYER:
sodium chloride- organe
sodium iodide- violet
explain how the students results provides evidence for the trend in reactivity of the halogens down group 17(7) and write and ionic equation for any reaction that takes place.
use your chemical knowledge to explain the trend in reactivity
can someone pls help me with this question
