We’re being asked to determine the appropriate solvent/s for barium nitrate (Ba(NO3)2) which is an ionic compound. Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.
Since Ba(NO3)2 is an ionic compound, an appropriate solvent is a polar compound with a strong IMF, which means there might be more than 1 correct answer for this problem. So for this, we need to draw the Lewis structures of the given choices and determine their polarity.
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present and draw the Lewis structure for the molecule.
Step 3: Determine the polarity of the molecule.
Pick an appropriate solvent to dissolve barium nitrate (ionic). Check all that apply.
a. Methanol (CH3OH)
b. Ethanol (CH3CH2OH)
c. Toluene (C7H8)
d. Carbon tetrachloride (CCl4)
e. Hexane (C6H14)
f. Water (H2O)
