Predicting Solubilities Decide which compound will be more likely to dissolve in the given liquid. Think about the IMF between the solvent and each solute. 1. Solvent: methanol (CH3OH) Solutes: carbon diselenide and oxygen dichloride - 2. Solvent: carbon disulfide Solutes: methanol (CH3OH) and lithium chloride 3. Solvent: water Solutes: carbon tetrachloride and ammonia

these are the unknowns
3. Consider "Like dissolves Like" Polar solutes dissolve in and solutes dissolve in nonpolar solvents. Compounds_ and ___ have bonds and are soluble in which is polar. Compound is not soluble in water but is soluble in nonpolar solvent called _so it has _bonds. Compound is soluble in water but does not electricity so it must have bonds joining some parts that are (polar, nonpolar) 4. Based on conductivity, a) Which of the unknowns are electrolytes?...

1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...
