What is the range of tds in seawater?
The total dissolved solids (TDS) in seawater typically range from 33,000 to 37,000 parts per million (ppm). This measurement includes salts, minerals, and other dissolved substances present in seawater.
How are density and salinity related?
Density and salinity are directly related in seawater - as salinity increases, the density of seawater also increases. This is because dissolved salts and other substances in seawater add mass without significantly changing the volume, thereby increasing the overall density. Conversely, a decrease in salinity will lead to a decrease in density.
What are the percentage of salt in seawater?
The average salinity of seawater is about 3.5%, which means that approximately 35 grams of salt are dissolved in 1,000 grams of seawater. This salinity can vary slightly depending on location and other factors.
Which ONE of the following is NOT one of the sources of dissolved salts in seawater?
Rainfall is NOT one of the sources of dissolved salts in seawater. Salt in seawater comes from the erosion of rocks on land, underwater volcanic activity, and the release of minerals from hydrothermal vents.
Why can't you just evaporate a liquid to find out what substances were dissolved in it?
Evaporating a liquid to determine its dissolved substances can be limited because some substances may decompose or react with each other upon evaporation, altering their original form. This can lead to inaccurate results. Additionally, some substances may not evaporate along with the solvent, leading to an incomplete analysis of the dissolved components.

What is dissolved in seawater?
Seawater contains a variety of dissolved substances, with the most abundant being sodium and chloride ions from salt (sodium chloride). Other common elements and compounds found in seawater include magnesium, calcium, sulfate, and bicarbonate ions, as well as dissolved gases like oxygen and carbon dioxide. Organic matter including proteins, carbohydrates, and fats also exist in seawater in smaller amounts.
Is seawater a element or compound?
Seawater is a mixture of different elements and compounds. It is primarily composed of water and contains dissolved salts, minerals, and other substances. So, seawater is not an element but a complex mixture of different compounds.
Is seawater an element?
No; seawater is essentially a mixture of water, salt and other substances such as sand.
Why is it correct to say seawater is a mixture?
Seawater is a mixture because it is a combination of different substances, such as salt, water, minerals, and other organic matter. These substances are not chemically bonded together, so they can be separated through physical processes like evaporation or filtration.
How are density and salinity related?
Density and salinity are directly related in seawater - as salinity increases, the density of seawater also increases. This is because dissolved salts and other substances in seawater add mass without significantly changing the volume, thereby increasing the overall density. Conversely, a decrease in salinity will lead to a decrease in density.
The dissolved materials in seawater are thought to originate from chemical weathering of rocks on the continents and also from?
volcanic activity on the ocean floor. These processes release ions and minerals into the water, contributing to the composition of seawater. Biological processes such as the decay of organic matter and the excretion of ions by organisms also play a role in the dissolved materials found in seawater.
What are the percentage of salt in seawater?
The average salinity of seawater is about 3.5%, which means that approximately 35 grams of salt are dissolved in 1,000 grams of seawater. This salinity can vary slightly depending on location and other factors.
What is the principal source of dissolved substance in ocean?
Chemical weathering of rocks on the continents is one source of elements found in seawater. The second major source of elements found in seawater is from earth's interior. Through volcanic eruptions, large quantities of water vapor and other gases have been emitted into the atmosphere.
What organ that filters wastes and other dissolved substances out of the blood?
liver
What organ filters waste and other dissolved substances out of the blood?
liver
Organs the filter waste and other dissolved substances out of the blood?
The kidneys.
