Define the terms hydrophobic and hydropholic and label the appropraite ends of the organic acid?

Answer 1

Semi-permeable, porous membranes useful as filtration and reverse osmosis membranes can have or can consist of a porous layer of a hydrophobic polymer rendered hydrophilic at its surface by the presence of a surfactant containing both hydrophobic and hydrophilic groups, the surfactant being bonded to the polymer. Such a membrane may be made by quenching a previously made dry membrane in a solution of the surfactant and then banking the membrane. Such a membrane may also be made by contacting a membrane manufactured by quenching a dope of the hydrophobic polymer with such a solution of the surfactant prior to the membrance being dried after being formed by quenching. Such a membrane can also be made by forming a dope of the hydrophobic polymer and the surfactant and then quenching the dope to form the membrane, this quenching serving to contact the membrane with the surfactant as it is being formed

Hydropholic:
A procedure is provided for the production of clean, dustless particulate granules from dusty, dirty particles by treatment with a composition comprising a liquid polymeric substance, illustratively, epoxidized soybean oil, and a solid, low molecular weight polymer having a melting point in the range of about 95.degree. to 105.degree. C., illustratively, a polyethylene vinyl acetate copolymer in the proportions of from 1 part of solid polymer to 1 part of liquid polymeric substance to 2 parts of solid polymer to 1 part of liquid polymeric substance. In one modification of the procedure, the ingredients were charged to a Papenmeir mixer and the mixer was run at 1500 RPM until a temperature of 95.degree. C. was reached. The resulting product comprised clean, dustless uniform beads.

Hydrophobic:
Lacking an affinity for water.

Having no affinity for water; not compatible with water. "Water fearing" Also preventing growth of mold and mildew.

("water-fearing") Pertaining to nonpolar molecules that disrupt the hydrogen-bonded structure of water without forming favorable interactions with the water molecules; thus, these molecules are insoluble in water.

[Greek, hydro= water + phobos = fear] Avoiding associations with water; nonpolar.

A property of an object or substrate that causes it to repel water.
www.rainwater.com/glossary/h.html
Means water insoluble and refers to non-polar properties as opposed to polar properties of water. Water soluble, or hydrophilic, molecules do not easily mix with hydrophobic molecules or solutions. Oil is a hydrophobic substance and mixtures of oily and watery molecules tend to minimize their contact surface. Thus the observed separation of oil from water when left standing. ...

aversion to water; a hydrophobic surface will not allow large puddles of water, but rather will form droplets. These surfaces are often termed “de-wetted.”

Water hating, preferring to be wet by oils rather than water. Water repellent. An image area on a plate is typically Hydrophobic.
www.tintas.com/spanish/tech_info/dictionary.html
Repelled by water. Having the property of not mixing readily with water. Hydrophobic compounds are typically non-polar compounds, without charged or electronegative atoms, and often contains many CH bonds.

Water fearing. A term applied to that portion of a detergent molecule that has an affinity for non-water surfaces or substances. The hydrophilic and hydrophobic portions of the detergent molecule have a direct and extremely important role to play in detergent function, such as defluculation, emulsification, suspension, etc. lacking the ability to absorb water.

abnormally afraid of water

In chemistry, Hydrophobe, from the Greek (hydros) "water" and (phobos) "fear", refers to a physical property of a molecule that is repelled by water. Hydrophobic molecules in water often cluster together.

Answer 2

Hydrophobic - afraid of water
Hydrophillic - loves water.

In an organic acid I'll assume you mean something like a fatty acid, a long carbon chain with a carboxylic acid at one end. The hydrophobic end is the carbon chain and the hydrophilic part is the carboxylic acid group.

Answer 3

The hydrophilic (water-loving) part of the molecule is the bit with the -COOH because it is polar and you get a bit of ionization plus hydrogen bonding with water molecules. The hydrophobic (water-fearing) part is the other end, probably ending in a methyl group (CH3), which has no affinity for water - a bit like Vaseline or engine oil.

Answer 4

Where is the organic acid? Do you have a picture of it, that would help. In the meantime, hydrophobic means water-hating, or a molecule that is nonpolar (uncharged) that does not like water. Hydrophilic means water-loving, or polar (two charges), usually a molecule that is soluble in water and is charged.

Answer 5

hydrophobic: water hating. The tendency to have an unfavourable interaction with water (due to high enthalpy, or lower entropy (or both) when in contact with water).
Its the CH3-CH2-... part of the organic acid.
hydrophilic: water loving. :) The tendency to have a favourable interaction with water.
Its the -COOH or -COOminus part of the organic acid.

Answer 6

hydrophobic : water hating or water repelling

hydrophillic : water loving or water attracting


where is the acid?

Answer 7

hydrophobic--afraid of water

hydropholic--absorbs water
