What is the major force that drives nonpolar substances out of aqueous solution?
Increased entropy of solvent water molecules.
What happens when granulated sugar touches water?
When granulated sugar and water come in contact, the water molecules surround the individual sugar molecules, and the sugar molecules go into solution. You end up with an aqueous solution of sugar.
Are transmembrane proteins amphipathic?
yes, transmembrane proteins have both polar and non-polar regions. This is because these proteins are dispersed through the membrane almost like pieces of stones. So, to be inside the hydrophobic region of the phospholipid bi-layer AND also outside of it in the water or aqueous solution they transmembrane protein needs to be amphipathic.
What is an aqueos solution?
An *aqueous* solution is formed when a substance is dissolved in water. The term "aqueous" stands for the latin word "aqua" which means water.
How is an aqueous solution different from other solutions?
In an aqueous solution the solvent is water.
What is the solution process with water as the solvent?
This solution is called water solution or aqueous solution.
What type of solution has the highest concentration of water molecules?
That is what is known as an aqueous solution.
What bond occurs in a phospholid?
Phospholipids are amphipathic molecules with two hydrophobic fatty acids and a hydrophilic phosphate-containing group linked to glycerol. When placed in an aqueous solution, water forms a shell around the hydrophobic lipid, a situation that not only prevents water from making hydrogen bonds with other water molecules, but also reduces freedom of movement, making the water molecules more ordered.
Why do amphipathic molecules form micelles in water?
Amphipathic molecules are by definition those that contain both hydrophobic (water hating) and hydrophilic (water loving) regions. The area of the molecule that likes water tends to stay in the aqueous region whereas the region of the molecules that hates water tends to cluster with other hydrophobic regions. This untimately results in the hydrophobic regions packing together and forming a region that is impervious to water molecules. Such a structure is called a micelle
What is the major force that drives nonpolar substances out of aqueous solution?
Increased entropy of solvent water molecules.
Why is sugar sweeter in aqueous solution than in the solid state?
In solution, sugar molecules can more easily reach the "sweet" receptors in the tongue.
Water is a solvent in a(n) what solution?
'An Aqueous' solution. NB The word 'aqueous' comes from Latin ; 'aqua' meaning 'water'.
What happens when granulated sugar touches water?
When granulated sugar and water come in contact, the water molecules surround the individual sugar molecules, and the sugar molecules go into solution. You end up with an aqueous solution of sugar.
What gives an aqueous solution of an acid the properties of an acid?
An acid gives its properties to an aqueous solution by making free its (acidical) H+ ions (protons) and donating this to the solvent molecules: water, so H3O+ is formed.
Do dipole orient themselves toward other dipole molecules?
Dipole molecules, those having a negatively charged pole and a positively charged pole, if they are in a liquid medium such as an aqueous solution, will orient themselves according to Coulomb's Law, with negative poles close to positive poles and distant from other negative poles.
Are transmembrane proteins amphipathic?
yes, transmembrane proteins have both polar and non-polar regions. This is because these proteins are dispersed through the membrane almost like pieces of stones. So, to be inside the hydrophobic region of the phospholipid bi-layer AND also outside of it in the water or aqueous solution they transmembrane protein needs to be amphipathic.
What is hydration of ion in aqueous solution?
The water molecules surround the negative ions and positive ions and pull them away into the solution. This process is called dissociation
