k3po4 ionic or covalent

Molecular Geometry

Molecular Geometry VSEPR At this point we are ready to explore the three dimensional structure of simple molecular (covalent) compounds and polyatomic ions We will use a model called the Valence Shell Electron-Pair Repulsion (VSEPR) model that is based on the repulsive behavior of electron-pairs This model is fairly powerful in its predictive capacity To use the model we will have to

Colligative Properties

Colligative Properties are based on the amount of a substance not what it is Quantity not quality Dissociation-when neutral combinations of particles separate into ions while in aqueous solution Up to this point you have only thought about solution as a particle dissolved in water This is true for many covalent compounds They remain intact (1 mole of particles) C 6 H 12 O 6(s) ==C 6 H

Classifying Electrolytes

Electrolytes are substances which when dissolved in water break up into cations (plus-charged ions) and anions (minus-charged ions) We say they ionize Strong electrolytes ionize completely () while weak electrolytes ionize only partially (usually on the order of 1–10%) That is the principal species in solution for strong electrolytes are ions while the principal specie in solution

Solution Chemistry

Earlier we learned that a homogeneous mixture of two or more substances is called a solution If one of the substances is present in much greater quantities than all the other substances then it is called the solvent The other substances in solution are known as solutes For example when a small amount of NH 4 Cl is dissolved in a large quantity of water we refer to water as the solvent and NH
