Mixtures and Solutions

Flashcards about Mixtures and Solutions

What are Heterogeneous Mixtures?

Mixtures with no uniform composition or which will eventually have no uniform composition.

Give some examples of Solid Heterogeneous Mixtures?

Trail mix, salad, your backpack, concrete.

Give some examples of Liquid Heterogeneous Mixtures?

Muddy water, oil and water, soups, milk.

Give some examples of Gas Heterogeneous Mixtures?

Smoke, fog, mist.

What is a Suspension?

Heterogeneous mixtures with large particles that will settle over time.

What are Colloids?

Heterogeneous mixtures with mid-sized particles which will not settle out over time.

What is the Tyndall effect?

The scattering of light when one shines a light into a colloid in contrast to light not scattering when shone through a solution.

What is Brownian motion?

Random motion of particles in a fluid due to their collision with the particles in the fluid.

What are Homogeneous Mixtures?

Mixtures with uniform composition.

What is a Solution?

Homogeneous mixtures in which one pure substance dissolves in another.

Give some examples of Solutions?

Salt water, sugar water, vinegar, etc.

What does Soluble mean?

Ability to dissolve in a certain substance.

What does Miscible mean?

Ability for a liquid to dissolve in a certain other liquid.

What does Insoluble mean?

Inability to dissolve in a certain substance.

What does Immiscible mean?

Inability for a liquid to dissolve in a certain other liquid.

What is Molarity?

Common measure of concentration that tells you how many moles of solute are dissolved per liter of solution.

What is Solvation or Dissolution?

The process in which solvent particles surround solute particles to form a solution.

What does Agitation mean in the context of dissolution?

Shake or stir the thing.

What does Surface area mean in the context of dissolution?

Break up the thing.

What does Temperature mean in the context of dissolution?

Heat the thing.

What is Solubility?

Property of a solute to dissolve in a particular solvent.

What does Saturated mean?

As much stuff as can be dissolved is dissolved.

What does Unsaturated mean?

As much stuff as can be dissolved is not dissolved.
