Differentiate between fresh water and sea water.
Answers
Answer:
Freshwater contains less than 0.05% salt, or less than 1% salt by some definitions. Brackish water contains less than 3% salt. And saltwater contains more than 3% salt.
Water is neutral, however it follows that the more salt you dissolve in water, the more basic it becomes (i.e pH greater than 7). Saltwater is therefore the most basic, followed by brackish water, and freshwater is the closest to neutral pH 7.
Seawater is very similar from place to place, where as freshwater varies a lot depending on the type of soil and rock the water is in contact with. Seawater can contain hundreds of trace elements including metals like lead and mercury. Seawater also contains large quantities of chlorine (twice as much even than salt), with somewhat smaller quantities of magnesium, sulphur, calcium, and potassium. Freshwater contains similar elements, but less of them making fresh water purer. Brackish is obviously where salt and fresh water meet and mix such as in estuaries and lakes.
The dissolved oxygen in water type also varies. Oxygen dissolves in freshwater more easily than brackish or salt water. Freshwater also gets the opportunity to dissolve oxygen more often, because of the nature of where you find it such as in small rivers where it flows faster. However temperature is probably the biggest factor when it comes to dissolved oxygen, not the type of water.
The salts that are found in salt water, as well as brackish water, along with other elements break down and become electrically charged ions. These particles are better electricity conductors. This means that electricity flows through salt water more readily and efficiently than it does through fresh water which is why choosing the right metal type for your water type is critical as they react differently depending on the salinity level.
Remember:
Fresh Water – Magnesium
Brackish Water – Aluminium
Salt Water – Zinc
Answer:
Perhaps the biggest difference is in the name itself. Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent.
