Which of the following best describes the components of seawater?
Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.
Why is sea water called a mixture?
Textbook solution The substances present in the mixture is not chemically combined. Sea-water is classified as a mixture. Because, sea-water is made up of more than two substances, that is salt and water. The salt is dissolved in water and the salt is consider as solute and water is consider as solvent.
What are the different components of salt solution seawater mixture?
Ocean water is a homogenous mixture of salt in water. It contains about 3 percent sodium chloride. Ocean water is the type of mixture called a solution, because the salt is dissolved in the water. Water is the solvent, and sodium chloride is the solute.
What are the properties of seawater?
Seawater has unique properties: it is saline, its freezing point is slightly lower than fresh water, its density is slightly higher, its electrical conductivity is much higher, and it is slightly basic.
What is the chemical formula of sea water?
The chemical composition of sea water is relatively simple to interpret – it’s H2O with a few extras. If you collect a sample of ocean water and take it to the laboratory, a chemist will quickly identify six major ions.
Why sea water can be classified as H * * * * * * * * * * as well as heterogeneous mixture?
This is because sea water can be classified as both homogeneous and heterogeneous mixture. It is called as homogeneous because it contains dissolved salts in it and it may be also called as heterogeneous as it contains various insoluble components too as sand, microbes etc. Hence, option A is correct.
What are 5 mixtures?
Other Common Mixtures
- Smoke and fog (Smog)
- Dirt and water (Mud)
- Sand, water and gravel (Cement)
- Water and salt (Sea water)
- Potassium nitrate, sulfur, and carbon (Gunpowder)
- Oxygen and water (Sea foam)
- Petroleum, hydrocarbons, and fuel additives (Gasoline)
Is salt a solute in seawater?
Ocean water is the type of mixture called a solution, because the salt is dissolved in the water. Water is the solvent, and sodium chloride is the solute.
What is the major property of seawater?
Answer: Temperate is one of the major property of seawater. It always varies from region to region. The surface temperature of the sea water decreases from the equatorial area towards the poles.
Is the major property of seawater?
The most important thermodynamic property of seawater for studies of oceanic circulation is its density (denoted ρ).
What are the six Colligative properties of seawater?
The colligative properties of seawater include:
- Electrically conductive. Ability to conduct an electrical current.
- Decreased heat capacity. Takes less heat to raise the temperature of seawater.
- Slowed evaporation. Seawater evaporates more slowly than fresh due to the attraction between ions and water molecules.
Can humans drink sea water?
Why can’t people drink sea water? Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body’s kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly.
What’s the difference between an ocean and a sea?
The term sea is used to describe the global, interconnected water body covering 70% of the Earth’s surface, whereas oceans refer to the individual basins within this global sea. An ocean is a vast body of water encompassing 70% of the Earth, whereas a sea refers specifically to a large, inland, saline body of water.
Which is the following statement best describes seawater?
Which of the following statements best describes seawater? Seawater is pure water (H20). Seawater is a solution. The chemical composition of seawater has little spatial variability. The salinity of seawater is negligible. the atmosphere only. minerals only.
What makes up the chemical composition of seawater?
The chemical composition of seawater has little spatial variability. The salinity of seawater is negligible. the atmosphere only. minerals only. marine organisms only. the atmosphere, marine organisms, minerals, and ocean sediments. 0.05%. 3.5%.
