Solution

a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase.

Soluble

capability of being dissolved

Solute

the substance being dissolved in a solution.

Solvent

dissolving medium in a solution

Which part of a solution is of larger quantity - the solute or solvent?

Solvent

What is an Alloy, give ex:

A uniform mixture of 2+ metals, Brass and Sterling Silver

What desired qualities do Alloys typically have

If u mess around with proportions, it can have better strength and resistance to corrosion. than pure metals

Suspension

A mixture where the particles in the solvent are so large that they settle down unless stirred.

Colloid

A mixture where the particles are intermediate in size based on the ones in the solutions vs ones in suspensions.

EX: Muddy water, the water is cloudy and there is stuff on the bottom.

What is Tyndall Effect? Give EX:

Particles in a colloid can be homogeneously mixed since we cant see them (salt water), but the particles are big enough to scatter light beams.

Electrolyte

Ionic Solutions that conduct electricity

dissolves in water to conduct electricity

EXAMPLE: Salt in water

Nonelectrolyte

substance that dissolves in water that doesn’t give the solution good conductivity

3 factors of the dissolving process

Increasing surface area of solute (crushing it)

Agitating a Solution (shaking it up)

Heating the solvent up

Saturated Solution

 a solution that contains the maximum amount of dissolved solute.

unsaturated solute

solution that contains less solute than a saturated solute

Supersaturated Solute

solution that contains more solute than the normal saturation

like disolves like means?

Polar dissolves polar and nonpolar dissolves nonpolar.

Immiscible

Liquids that aren’t soluble in eachother

EXAMPLE Oil mixed with Water

Miscible

liquids that dissolve freely in one another in any proportion.

Effervescence

rapid escape of a gas from a liquid in which its dissolved

hand sanitizer and boiling water i guess

Dissociation

the separation of ions that occurs when an ionic compound dissolves.

Ionization

the process of ions that are formed from solute molecules by the action of the solvent.

how is dissociation and ionization different

• Dissociation: ionic compound → existing ions separate.

  • Ionization: molecular compound → new ions are created

Difference between strong and weak electrolyte

They differ in the amount of dissociation or ionization

Colligative Properties

properties that depend on the concentration of the solute particles, but not on their identity.
