Web of Chemistry Knowledge
Solution
A solution is made by dissolving solute in a solvent.
Solution
Homegenous Mixture
Solute
Material that is dissolving, often in a lower amount.
Solvent
Material that dissolves, often present in greater amounts.
Soluble/Insoluble
Soluble
Solid solute completely dissolved in the liquid solvent.
Insoluble
Solid solute did not dissolved in the liquid solvent.
Concentration
Relative amounts of solute and solvent.
Diluted
Less amount of solute in a less amount of solvent.
Concentrated
More amount ofsolute in a lessamount of solvent.
Units of Concentration
Percent by Mass (%m/m)
Percent by Volume (%v/v)
Mass/Volume Percent (%m/v)
Parts per Million (ppm)
Parts per Billion (ppb)
Solubility
If the solvent's polarity and the solute's polarity are comparable, the solvent will dissolve the solute.
Factors that Affect Solubility
Structure
If the solvent's polarity and the solute's polarity are comparable, the solvent will dissolve the solute.
Temperature
Most solids become more soluble in water as the solution's temperature rises. But as temperature rises, gases become less soluble.
Pressure
The solubility of gases is exactly proportional to the pressure of the gas above the liquid (but not of liquids or solids).
Types of Solution
Unsaturated
Contains less solute than a saturated solution.
Satured
Contains the maximum amount of solute in a given amount of solvent.
Supersaturated
Contains more solute than a saturated solution.
Matter
Matter is anything that occupies space and has mass
Properties of Matter
Characteristics that allows a matter to be distinguisable from other substance
Physical Properties
Physical property is a characteristic that observe and measure without changing the composition of a substance.
Kinds of Physical Properties
Intensive property, does not depend on the amount of substance being examinded
Extensive property, depends on the amount of the substance.
Physical Changes
Process wherein the physical properties of a substance changes without changes from the chemical composition.
Chemical Properties
Chemical properties are descriptions of the ability of a substance to undergo a chemicalchange.
Chemical Changes
Chemical change is a process where one or more substancesare converted into one or more new substances, may be called chemical reaction.
Evidence
Permanent or sudden change in color, temperature, or odor, bubbling, evolution of gas, formation of precipitate
States of Matter
Three States of Matter
Physical Properties
Solid
Has a fixed shape where it remains rigid and not set by container.
Liquid
Has no fixed shape and can be poured. It also takes the filled shape of the container.
Gas
Has no fixed shape and also takes up and fills the shape of the container.
Molecular Level
Solid
Has little spaces in between particles but vibrates on their position. There's little to no volume change when applied moderate pressure.
Liquid
Has some free space in between particles where it moves past from one another. It is compressed lightly when moderate pressure is applied.
Gas
Has wide space wherein particles moves freely. It is compressed when moderate pressure is applied.
Kinetic Molecular Theory of Matter
All matter consists of extremely tiny particles which are in constant motion.
Kinetic Energy
It is the energy of the moving object.
If the speed of the object increases, the kinetic energy increases as well. Hence, when the speed of the object decreases, the kinetic energy decreases.
When particles are heated, they move faster. thus, when they are cooled, they move slower.
Transformation of Different States
Melting - Solid to Liquid
Evaporation - Liquid to Gas
Sublimation - Solid to Gas
Condensation - Gas to Liquid
Freezing - Liquid to Solid
Deposition - Gas to Solid
Classification of Matter
Atom is the smallest unit of matter that retains its chemical properties
Molecules are composed of two or more atoms bound together in a discretearrangement.
Pure Substance
Composed of one pure substance that has a fixed chemical composition.
Element
Substance that cannot be broken down into simpler substances even by a chemical reaction.
Compound
Substance composed of two or more elements combined in definite proportions.
Mixture
Composed of two or more pure substances and may or may not have uniform composition.
Heteregenous
Mixture in which the composition is uniform throughout the mixture.
Homogenous
Mixture in which the composition is not uniform throughout the mixture.
