Document Summary

Particles cannot be filtered from its other components. Solution- a homogenous mixture that contains small particles. A solution is likely to form when the solute and the solvent have similar properties. Dilution: the addition of solvent in a solution to decrease the concentration of the solute. Suspension: a heterogeneous mixture that contains large particles suspended in a liquid compound. Electrolyte: a substance that conducts an electrical current in water. Nonelectrolyte: a su(cid:271)sta(cid:374)(cid:272)e that does(cid:374)"t (cid:272)o(cid:374)du(cid:272)t a(cid:374) ele(cid:272)t(cid:396)i(cid:272)al (cid:272)u(cid:396)(cid:396)e(cid:374)t i(cid:374) (cid:449)ate(cid:396) Equivalent- number of moles of charge that a mole of ions contributes to a solution. Strong electrolyte dissociates completely in water to form ions.

The amount of a solute that dissolves in a given amount of solvent. Saturated solution: contains the maximum number of grams of solute that can dissolve.
