Because it can dissolve a wide variety of substances.
“Like dissolves like.”
Serve as solvent (blood and cells), temperature regulation, saliva (digestive), joint lubrication (e.g. synovial fluid), blood pressure regulation, air moisturization, nutrients transportation, shock absorber, hydrolysis reactions.
Water molecules exist in equilibrium with hydrogen ions (H+) and hydroxide ions (OH-).
A homogeneous mixture that contains small dissolved particles.
When it contains dissolved ions.
It allows water to absorb a lot of heat before it evaporates, helping to regulate temperature.
Anions are surrounded by a hydration shell of water molecules arranged with their hydrogen atoms closest to the anion.
Yes, any phase of matter can form solutions.
Because oxygen is more electronegative compared to hydrogen, leading to uneven sharing of electrons and partial charges on the atoms.
A minor component of a solution that is dissolved in the solvent.
Hydrogen bonds are strong enough to dissolve polar molecules and separate charges but weak enough to allow movement of water and solutes.
Blood or some drugs.
High heat of vaporization, strong surface tension, high specific heat capacity, and high boiling point.
Due to hydrogen bonds and electrostatic interactions with water molecules.
A solution where water is used as the solvent.
It indicates that the equilibrium favors the reactant (water molecules), meaning only very small amounts of H+ and OH- ions are present.
The substance present in a lesser amount.
A liquid in which a solute is dissolved to form a solution.
The oxygen atom of water interacts with inorganic cations to surround them with a hydration shell.
Yes, if the attractive forces between ions and water are stronger than the attraction between the ions in the crystal.
Due to hydrogen bonding between water molecules.
A mixture in which particles are dispersed throughout the bulk of a fluid but are not dissolved.
Kw = [H+][OH-]
The substance present in a larger amount.
Electrostatic attraction.
In a suspension, particles are finely divided but not dissolved, unlike in a solution.
H+ = OH- = 10^-7
Yes, compounds with many nonpolar C-C and C-H bonds are soluble in nonpolar solvents.
A liquid mixture in which a minor solute is uniformly distributed within the solvent.
When it contains atoms or neutral molecules.
Yes, they are soluble in water.
Water is composed of 2 hydrogen atoms and 1 oxygen atom.
