We have a compound Cr(NO2)3 and we have to determine if this is an ionic compound and whether it is soluble in water or not.
We have to look at what ions this compound is made up of and we will go through each statement one by one.
Cr + (-3) = 0
Cr – 3 = 0
Cr = +3
Which of the following describes the compound Cr(NO2)3? Choose all answers that apply.
a. The compound would be expected to have a relatively low melting point.
b. The compound is ionic.
c. If the compound dissolved in water it would be a strong electrolyte.
d. The compound would conduct electricity if molten.
e. The compound is molecular.
