Solution=

Solute+solvent

What is a strong electrolyte?

Salt that readily ionizes,splits, in water what i

What is a weak electrolyte?

Salt that will lose one ion off a molecule in water

What does increased temperature do to solubility ? (Solubility curve)

Increasing temp increases solubility

What is Henry’s law?

If a cap is put on a container then the molecules that have converted from liquid to gas will be forced back into the liquid phase.

What is the mass percent equation?

Mass of the solute/mass of the solvent+solute *100

What is the mass volume percent equation ?

Grams of solute/milliliters of solution *100

What is the equation for molarity?

Mols of the solute/liters of solution

What is the equation for dilution of a solution ?

Dilution =c1*v1=c2*v2

What is boiling point elevation?

The boiling point of a substance is elevated when more solution is added

Isotonic

An even amount of water entering or leaving the cell

Hypertonic
