1. The document is a chemistry quiz that asks the student to identify the best solvent to dissolve various substances based on the principle of "like dissolves like". 2. For oil-based paint, the student identifies carbon tetrachloride and n-hexane as good solvents because they can dissolve other non-polar organic materials like oils and grease. 3. For latex paint, the student explains that water is a suitable solvent because latex paint is water-based and ionic/polar compounds dissolve in polar solvents like water.

CHEMISTRY 1
NAME: Tupaz, IshiPearlC.
SECTION: BMLS 1-E
I. Given the following solvents:
a. water
b. isopropyl
c. n-hexane
d. carbon tetrachloride
Using the general rule that like dissolves like, which solventwould you choose to
dissolvethe following? Justify your answers.
1. Bike
2. Oil-based paint
3. Latex paint
4. Soap
5. Candle wax
6. Dichlorodiphenyltrichloro ethane, DDT
Answer:
1. Ma’amI don’tknowpo which solventstatedabovecan dissolvea wholebike.
2. Carbon tetrachloride and n-hexane can dissolve oil-based paint because
other organic materials such as oils, fats and grease are dissolved very well
by carbon tetrachloride and because oil-based paint and n-hexane are non-
polar, n-hexane can dissolve oil-based paint.
3. Latex or water-based paints can be cleaned up with just soap and water
because ionic and polar compounds dissolve in polar solvents.
4. The soap becauseof the two separateparts of the molecule can be dissolved
bywater, thesoap moleculeis watersolubleand can dissolvefatsatthe same

2. time. The fats are drawn to the soap's non-polar tail part, while the polar
head dissolves the entire complex (soap + fat) in water.
5. Since carbon dissolves other organic materials such as oils, fats and grease
very well, Isopropyl can dissolve candle wax.
6. Using carbon tetrachloride because DDT can dissolve dichlorodiphenyl
trichloro ethane or DDT is extremely fat soluble (dissolves easily in fat), but
is poorly insoluble in water. Itappears to accumulate in the fatty tissues due
to its " fat loving " nature.
