Homogenous, 1nm-1um, and not transparent are __

Colloid

What can light not pass through (For example water and milk)

A colloid

What solution has less than maximum amount of solute that can dissolve in the solvent?

Unsaturated solution

What solution has the maximum amount of solute that can dissolve in the solvent?

Saturated solution

Soluble is what

dissolves

Insoluble is what

does not dissolve

What compound uses the term like dissolves like ? For example Polar + Polar= Soluble

Molecular compounds

For Ionic Compounds Group 1A, Ammonium, Nitrate, and Acetate are ?

always soluble

For Ionic compounds, Hallid’s (F,Cl,Br,I) are always soluble unless paired with what?

Ag, Mg, Pb

For Ionic Compounds, Sulfate is soluble unless paired with

Hg,Pb,Ca,Sr, and Ba

Define a Solution

The mix of a Solute and a Solvent. Solute being added to a solvent with solute having less amount and solvent having most amount

Define solubility

How much can be dissolved

Solid in liquids , Whats the change between Temperature and solubility?

Temperature goes up, and solubility goes up

Gases in Liquids, what’s the change between Temperature and Solubility?

Temperature goes up, and solubility goes down

Electrolytes

Substances that form Ions in solution

What electrolytes Break into ions and are great conductors ?

Strong Electrolytes

What electrolytes partially break apart ?

Non electrolytes

Concentration =

solute/solution

What is Dilution?

The process of adding more solvent to lower concentration

What is Osmosis?

The process of solvent moving across a semipermeable membrane toward the higher concentration

Solvent always moves to the side with the higher concentration of solution ..

Osmotomic Pressure

What is the normal Saline Solution of a happy balanced cell ?

0.9% NaCl or 5% glucose

What is the process of an isotomic soultion?

The Concentration of the soultion is equal to the concentration inside the cell

What is the process of an Hypotonic soultion?

The Concentration of a cell is higher than the concentration of the solution, causing it to swell and rupture (hemolysis)

What is the process of an Hypertomic soultion?

The concentration of a cell is lower than the concentration of the soultion, which will cause the cell to shrink (crenation)

What is Dialysis?

Water aand small ions move, leaving proteins
