Salt or sodium chloride one is a metal poisonous and the other is gas poisonous to humans but combined is beneficial t humans. A very long time ago the seas were not salty . Salt comes from the earth as a solvent element when rains washes it eventually to the seas as consequence the seas are getting saltier and saltier .
What else can I help you with?
Is seawater is mixture?
yes
What is the matter of seawater?
Sea water is water with a few thousand different dissolved salts and a variety of dissolved or suspended organic compounds.
Difference between seawater and fresh water?
Seawater has a higher salinity level due to dissolved salts, whereas fresh water has a very low salinity level. Seawater is found in oceans and contains various minerals, while fresh water is found in rivers, lakes, and underground reservoirs. Seawater is not suitable for drinking or agriculture without desalination, while fresh water is typically safe for consumption and irrigation needs.
What contains dissolved salts and minerals?
Seawater, underground aquifers, and mineral springs typically contain dissolved salts and minerals. These dissolved substances contribute to the flavor and composition of the water, and are essential for the health of aquatic life.
The proportion of dissolved substances in sea water is usually expressed in?
The proportion of dissolved substances in seawater is typically expressed in parts per thousand (ppt) or salinity, which is the concentration of dissolved salts in seawater.
Is ground water salt water?
groundwater can be fresh, or can have various salts and/or minerals dissolved in it
What are the materials needed to obtain fresh water from seawater?
It will need a Reverse Osmosis membrane to filter out salts from the water.
What is heavier sea or fresh water?
Technically, neither. They are both the same weight but not exactly weigh anything as water can alter our weight.
Is evaporating steam from sea water reversible?
Yes, the process of evaporating steam from seawater is reversible. When seawater is heated, it turns into steam through evaporation, which can then condense back into liquid water when cooled. This phase change is part of the water cycle and can be repeated multiple times. However, the dissolved salts and impurities in seawater do not evaporate with the water, so the condensed water would be fresh, while the remaining seawater would be saltier.
How is the sea water purified into drinking water in United Arab Emirates?
The process is called desalinisation. There are a few processes, but the main ones is done by heat. It involves taking seawater (which is water containing dissolved salts). Heating the seawater to boiling point and allowing, the pure water evaporates as steam, the steam is collected and condensed back into fresh water. The dissolved salts cannot evaporate become concentrated as "brine", this concentrated salt water is then pumped back into the sea, and the fresh water pumped to consumers. Most emirates use natural gas (which is abundant in the region) to heat the water to boiling point.
Which type of water is denser fresh water or salt water?
Water that contains dissolved salts is more dense than pure water; consequently, seawater is denser or has more mass per unit volume than freshwater. Temperature, however, is one of the most important factors controlling density in the ocean.
What percentage of 100mls of seawater is pure water?
It varies depending on what part of the ocean it is measured. Approximately 96.5% of seawater is water. The rest is dissolved salts. See related link for more information.
