Question

distinguish between sea water from pure water​

Answer 1

Answer:

Seawater covers 70% of the earth’s surface; it is salty and contains about 2.5% of dissolved salts. Main constituents include chloride, sodium, magnesium, calcium, sulfate, and potassium. In many parts of the world, salt (sodium chloride) is produced by evaporating seawater. Due to the high salt content, sea water is not suitable for domestic supply or for irrigation.

Generally the term freshwater is used for water suitable for domestic use. Probably the purest freshwater is rainwater; however, even rainwater picks up contaminants from the atmosphere. As rainwater infiltrates into the ground or flows through the streams and rivers, it picks some minerals. So domestic supply water also contains some dissolved solids, usually less than 1000 ppm (total dissolved solids or TDS) compared to over 35,000 ppm TDS for seawater.

In areas where freshwater is scarce, seawater is desalinated (a process by which most of the salt is removed) and is then used for domestic supply.

Answer 2

Explanation:

difference are below =

sea water = In sea water lot of salt is mixed. in sea water lot of algae and other animals are there. we never drink see water. it is not good for our body. Seawater's freezing point is lower than that of pure water and its boiling point is higher. It is easier to float objects in seawater than in fresh water.

pure water = we can drink pure water. pure water is good for our health. pure water's freezing point is higher then sea water. pure water has low boiling point then sea water.
