SOLUTIONS AND ACIDS, BASES, SALTS AND NEUTRALIZATION Flashcards
Mixture in which one substance is evenly mixed with another substance.
Solution
Go into solution.
Dissolve
Not able to dissolve.
Insoluble
Able to dissolve.
Soluble
Substance in which a solute dissolves.
Solvent
Molecules in which one end has a positive charge and the other end has a negative charge.
Polar molecule
Solution form when a solute dissolves in a solvent.
Stirring
Strong solution.
Concentrated Solution
Weak solution.
Dilute solution
Solution containing all the solute it can hold at a given temperature.
Saturated solution
Solution containing less solute than it can hold at a given temperature.
Unsaturated solution
Temperature at which a liquid changes to a solid.
Freezing point
Lowering the freezing point of a liquid solvent by adding solute.
Freezing point depression
Temperature at which a liquid changes to a gas.
Boiling point
Raising the boiling point of a liquid solvent by adding solute.
Boiling point elevation
Solution containing more solute than it can normally hold at a given temperature.
Supersaturated solution
Cloudy mixture of two or more substances that settle on standing.
Suspension
Use of chemicals to make the particles in a suspension clump together.
Coagulation
Separation of particles in a suspension by passing it through paper or other substances.
Filtration
Suspension of two liquids.
Emulsion
Suspension in which the particles are permanently suspended.
Colloids
Two or more substances that have been mixed together but not chemically combined.
Mixture
Smallest part of a substance that has all the properties of the substance matter.
Molecule
Is a material formed by chemically bonding two or more chemical elements.
Compound
Material that blocks light.
Opaque
Substance that reacts with metals to release Hydrogen.
Acids
Substance formed when metals react with water.
Bases
Negative ion is made up of one atom of hydrogen and one atom of Oxygen.
Hydroxyl
Substance that changes color in acids and bases.
Indicator
Litmus paper can be used to identify an acid or a base.
Litmus
Neither acidic or basic
Neutral
Measure of the concentration of hydrogen or hydroxyl ions in a solution.
pH scale
Reaction between an acid and a base produces salt and water.
Neutralization
Chemical formula : NaCl
Salt
Occur when parts of two ionic compounds are exchanged, making two new compounds
Double replacement
Are solutions with uniform composition and properties
throughout the solution.
Homogeneous solution
Are solutions with non-uniform composition and
properties throughout the solution.
Heterogeneous solution
Chemical formula : CaCl2
Calcium chloride
- Is a measure of the average kinetic energy of the particles in an object.
- When the temperature increases, the motion of these
particles also increases. - Temperature is measured with a thermometer or a
calorimeter.
