Which solvent will dissolve fingerprint marks(oil) ? water or chloroform Solutions Warmup Answer Section SHORT ANSWER 1. ANS: solubility = 14.3 g per 100 g water molality = moles per kg solvent molality= sol/100*10(100’s/kg)/molarmass= 1.12 m molality= 14.3/100*10(100’s/kg)/127.5495= 1.12 m PTS: 1 2. ANS: solvent solute PTS: 1 3. ANS: temperature molecular mass polarity of solvent and solute (same ionic polar ok ionic nonpolar notok) PTS: 1 4. ANS: temperature agitation particle size PTS: 1 5. ANS: Homogeneity absense of settling particles will subdivide (dissolve) PTS: 1 6. ANS: it will have a negative slope (decrease with increase in temperature) PTS: 1 7. ANS: The polarity of water “binds” molcules together, density of oil causes it to rise to top. PTS: 1 8. ANS: Liquids that do not mix together, like oil and water. PTS: 1 9. ANS: water, because like dissolves like polar or ionic ok nonpolar with polar of ionic not ok nonpolar - nonpolar ok PTS: 3 10. ANS: water, because like dissolves like polar or ionic ok nonpolar with polar of ionic not ok nonpolar - nonpolar ok PTS: 3
