Week 1 Content

What is Molarity (M)?

moles of solute/(per) liter of solution

What are aqueous solutions?

water mixtures

What’s a solute?

the thing that gets dissolved

What’s a solvent?

medium that the solute get’s dissolved into

What’s Soluble mean?

able to diffuse into something (there can be limits to this)

What’s miscible mean?

able to form a homogeneous mixture w/ other substance.

Soluble VS. Miscible?

generally is applicable to things VS. 2 substances that are liquids being mixed.

What’s Aqueous mean?

H2O mixture that is homogenous

What does Precipitate mean as a noun?

un-dissolved solid that isn’t in a liquid or solution

What does Precipitate mean as a verb?

the formation of a solid from a liquid or solution

What’s a Covalent bond? what element type is it usually bonded with?

shared e- (non metals)

What’s a Ionic bond? what element type is it usually bonded with?

element/compound will take an electron (metal to non-metal) (ion to ion)

When writing the formula for ionic bonds what element comes 1st then 2nd?

1. Metal

2. Non metal

What’s a SN #?

number of atoms bonded & any lone pairs in relation to the central atom

What’s a dipole dipole force?

when dipoles interact w/ each other

What is a Hydrogen bond?

still a dipole dipole interaction but is a much stronger. Only consist of (N-H, O-H & F-H)

What are the most electronegative atoms?

N, O & F

What are London Dispersion forces?

momentary dipoles, very weak (non-polar covalent can do this too)

What’s an electrolyte?

substance that produces ions in a solution when it dissolves into H2O

What’s an electrolyte solution?

solution that can conduct electricity

what are nonelectroyes?

don’t produce ions in solution & can’t conduct electricity

when it comes to electrolytes → the greater degree of ionization it will correspond …..

with stronger electrolytes.
