minerals and soluability and stuff test 1

if it can be physically pulled apart or not.

if its composed of a solvent and a solute.

dissolving a substance in water is often a prerequisite for chemical change.

individual entities of solute dispersing through ought a solvent.

ionic compounds seperating into there ions.

process by which an electrically neutral atom or molecule is converted to an ion. usually happens to acids.

• ionic compunds: dissocciate into ions which cause solution to conduct electricity. 
• bases: dissociate into ions which cause solution to conduct electricity.
• acids: ionize in water to form ions.

• 1. bonds between particles of the solute break (this process is endothermic)
• 2. some of the intermolecular forces in the solvent also break (endothermic)
• 3. attraction between particles of the solvent and solute result in new intermoleculer chemical bonds (exothermic)

its endothermic if energy is absorbed from its surroundings, its exothermic if energy is released into the surroundings.

a solution in which no more solute can dissolve, the solution is at maximum concentration.

some solute can still be dissolved in it.

there is an excess of solute dissolved per solvent. this happens when you stir or other means of agitation.

the concentration of a saturated solution.

temperature, pressure and chemical properties of both solute and solvent such as polarity.

• solids have high solubility at high temps
• gases have high solubility in low temps and high pressure.
• liquids have high solubility in water at high temps
• elements have low soluability
• ionic compounds you have to find out
• molecular compounds have higher solubility if there polar or have hydrogen bonding.

dissolving and crystalization are taking place at the same rate.

compares quanitity of solute to quanitity of solution.

measure of
