The Inorganic Chemistry – Flashcards

question
-A solution occurs when molecules of the substance are evenly dispersed among molecules of another substance. -Homogeneous and Heterogeneous are the two forms of mixture
answer
What are the two kinds of mixtures? What is a solution?
question
The combination of two or more substances that are not chemically bonded and not fixed proportions to one another. There are two forms of mixture. Homozygous and Heterozygous are the two forms of mixture.
answer
What is a mixture?
question
Most abundant substance in a solution and is usually a liquid, but can consist of a liquid, solid,mor gas also known as the phases of matter.
answer
What is a solvent?
question
answer
Ionic bonding?
question
Due to its polar nature its able to be apart of both forms of mixtures.
answer
Water is a good solvent?
question
Molecules have no charge and are considered neutral
answer
Non ionic bond
question
Molecules have a charge and are never neutral
answer
Ionic
question
So many substances can dissolve into water in various ways
answer
Water is a universal solvent?
question
What is salinity?
answer
Includes total concentration or quantity of all dissolved inorganic solids or more precisely ions called dissolved salts.
question
35, which is equivalent to 35 ppt 35g/kg Kg= 10 Various in salinity as small as 0.01 are of great value significance to oceanographers.
answer
Average Salinity
question
There's a great deal of variations of salinity in specific areas: from near zero at the mouths of rivers to more than (40 ppt) in confined areas like the Red Sea.
answer
Variations
question
Proportion of salinity doesn't change in seawater, only the amount of relative water changes. Salinity changes when when freshwater enters into the ocean mostly from rivers and rain or even as water evaporates.
answer
Proportion
question
Results when freshwater mixes into estuaries with a total salinity of (0.6 ppt) to (30 ppt).
answer
Brackish water
question
Saturated or nearly saturated with dissolved salts which develop in areas with high evaporation and little inflow of freshwater. Brine also develops where salt domes dissolve at the seafloor, as common as in the Gulf of Mexico.
answer
Brine water
question
Most dissolved salts in seawater exist as dissociated ions.
answer
Disassociated Ions
question
-Halite - most abundant of all Hamites is (NACl)
answer
Sodium Chloride (rock salt)
question
Properties of a liquid that may be altered by the presence of a solute Ex. Since pure water has nothing dissolved into it, it has no colligative properties. Colligative properties usually have to do with seawater. Freshwater can have Colligative properties as well but not as much as seawater. The quantity of the solute decides how strong the Colligative properties will be.
answer
Colligative Properties
question
-Raised Boiling Point: Seawater boils at a slightly higher temperature than pure fresh water. -Decreased Freezing Temperature: As salinity increases, water resist freezing. This is why salt is sometimes used on the road during ice and snowstorms. Seawater freezes at a slightly lower temperature than fresh water. -Ability to Create Osmotic Pressure: (osmos means to thrust) A law if chemistry that fluids diffuse from high area to low area of concentration until concentration equalizes. -If there is seawater on one side of a semipermeable membrane and fresh water in the other, a pressure exist from the fresh waters tendency to diffuse through the membrane.
answer
Colligative Properties of Seawater
question
Reached once enough water has moved to equalize the solute concentration on both sides of the membrane.Osmosis and Osmotic pressure are crucial to many biological process.
answer
Equilibrium
question
-Electrically conductive : Salts in seawater act as electrolytes, substances that conduct electricity once dissolved in water. -Decreased Heat Capacity: it takes less heat to raise the temperature if seawater than to raise fresh water to the same degree - Slowed Evaporation: attraction between ions and water molecules keeps water from evaporating easily. Seawater will evaporate more slowly than fresh water, all else being equal.
answer
Colligative Properties
question
Th constant relationship of proportions in seawater.
answer
Principle of Constant Proportion
question
Dissolved salts that do not change proportions
answer
Conservative Constinuients
question
No matter how much the salinity varies, the proportions of several key inorganic elements and compounds DO NOT ChANGE. This is useful because when you know how much of one element there is, you can determine how much there is of all of the other elements as well. Only the amount of water and salinity changes.

CTD
question
Thermistor, which is a semiconductor having resistance that varies and predictably with temperature
answer
Temperature is measured by a
question
Is determined by measuring current flowing between two platinum electrodes sealed in a tube of non conducting glass.
answer
Conductivity
question
Constant runoff, rain, erosion, and other natural forces create sea salts.
answer
Where do sea salts come from?
question
No it's it, it's actually pretty steady and there's no signs of the ocean becoming more or less saltier.
answer
Is the ocean getting saltier?
question
Tropical regions tend to be saltier than temperate regions
