Heterogeneous mixture

Ace your homework & exams now with Quizwiz!

Freezing point

...of a solution will decrease when a solute is added

Boiling point

...of a solution will increase when the solute is added.

Emulsion

A colloid in which liquids that don't mix are spread throughout each other. Ex cream. Appear uniform but it's not

Solubility curve

A comparison of the solubility of a substance when the temperature of the solvent is varied

Homogeneous mixture

A mixture that looks uniform even when examined closely bc individual components are evenly dispersed and too small to be seen. All are solutions

Suspension

A mixture where particles can settle out when allowed to stand. Filtered Are immiscible

Colloid

A mixture with smaller particles of a suspension and they dispersed throughout each other. (Can't filter)

Non polar m

A molecule where electrons are shared equally in a covalent bond

Polar molecules

A molecule where electrons are shared unequally in a covalent bond

Ionizing

A process where ions are formed when a substance is dissolved in water

Concentrated

A solution with a large amount of solute.

Dilute

A solution with a small amount of solute

pH

A value that identifies the concentration of H+1 ions in a solution, which is used to determine how acidic or basic solution is

Strong acids

Acids that are completely ionized in aqueous solution (100%)

Weak acids

Acids that ionize slightly in aqueous solution.

Colligative properties

Any property that can be changed due to change in the number of particles in the solution 1.conductivity 2.boiling point 3.freezing point

Strong base

Bases that complete dissociate to form OH-1 ions

Weak bases

Bases that react with water to form the hydroxide ion and the conjugate acid of the base.

Acids

Compounds that form hydrogen compounds when dissolved in water

Bases

Compounds that form hydroxide ions when dissolved in water. OH-1

Unsaturated solution

Contains less than the maximum amount of solute to dissolve in a solvent

Supersaturated solution

Contains more than the maximum solute that can be dissolved at that temperature in a solvent

Saturated solution

Contains the maximum amount of solute that can dissolve in a solvent

Strong electrolytes

Electrolytes where nearly all the solute dissolves in the solvent and separates

Alloy

Homogenous mixture of two or more metals

Heyerogenous mixture

Mixtures that dont have fixed compisitions. Can see the diff. phased

Salt refers to any ionic compound

Negative and positive. Metal plus nonmetal

Hydrogen bonds

Occurs when a hydrogen atom bonded to a highly electronegitive atom is attracted to a lone pair on an atom in another molecule

Neutralization Reactions

Reactions in which a acid and a base react

Electrolytes

Solutes in solutions that will conduct electric currents

Non electrolytes

Solutes in solvents that will not conduct electric currents

Conductivity

Special material that conducts electricity. -it's determined based on the solute Ionic conducts and covalent won't conduct electricity

3 types of heterogenous mixtures

Suspension colloid Emulsion

Solubility

The maximum amount of solute that can dissolve in a 100 g of a solvent at a certain temperature and pressure.

Solvation

The process of the solvent surrounding the solute for dissolving

Concentration

The quantity of solute that is dissolved in a given volume of solution

Tyndall effect

The scattering of light due to particles in a mixture

Solvent

The substance that dissolves the solute

Solute

The substance that dissolves. Separates into the smallest particles.

Indicators

Ways to measure pH. They change colors in specific ranges to determine if a substance is acid or base

Weak electrolytes

When only some on the solute dissolves in solvent and separates

Dissociate

When the compound splits to form two new ions
