1.2 solubility in water Flashcards
Solute
A solid that dissolves in a solvent
Solution
A mixture of a solute dissolved in a solvent
Solubility
The ability of a solute to dissolve within a solvent (such as water)
Dissolution
The process of being dissolved
Salinity
A measure of the quantity of dissolved solids in ocean water, represented by parts per thousand (ppt)
Precipitation
Water that falls from the atmosphere to the Earth’s surface as rain, sleet, snow, or hail
Run-off
The flow of water from land caused by precipitation
Evaporation
a change in state from liquid to gas below the boiling point of a substance
Hypersaline
When a body of water has a salinity level greater than 40 ppt
Halocline
A layer of water below the mixed surface layer where a rapid change in salinity can be measured as depth increases
Thermocline
A layer between two layers of water with different temperatures
pH
A numeric value expressing the acidity or alkalinity of a solution on a logarithmic scale
Acidic
Having a pH below 7
Alkaline
Having a pH above 7
Neutral
Having a pH that equals 7
