Which of the following is a conservative constituent of the oceans?
a) Na, K, SO4, Br, B and F have constant ratios to Cl and each other, everywhere in the ocean. These elements are conservative.
What are the non-conservative constituents found in the ocean?
Other non-conservative components include Ca2 + and SiO4 2 . These ions are incorporated into the solid parts of marine organisms, which sink to greater depths after the organisms die. The silica gradually dissolves, since the water is everywhere undersaturated in this substance.

Does the ocean have salt?
The concentration of salt in seawater (its salinity) is about 35 parts per thousand; in other words, about 3.5% of the weight of seawater comes from the dissolved salts. In a cubic mile of seawater, the weight of the salt (as sodium chloride) would be about 120 million tons.
What are the 8 constituents parts of seawater?
The average concentration of the important constituents (in parts per million) is: bicarbonate, 58.4; sulfate, 11.2; chloride, 7.8; nitrate, 1.0; calcium, 15.0; magnesium, 4.1; sodium, 6.3; potassium, 2.3; iron, 0.67; and silica, 13.1.
What are the two principle dissolved constituents in river water?
The dissolved load of the world’s rivers comes from the following sources: 7 percent from beds of halite (NaCl) and salt disseminated in rocks, 10 percent from gypsum (CaSO42H2O) and anhydrite (CaSO4) deposits and sulfate salts disseminated in rocks, 38 percent from limestones and dolomites, and 45 percent from the …

What are the 4 most common ions in seawater in order from greatest to least?
The most abundant dissolved ions in seawater are sodium, chloride, magnesium, sulfate and calcium.
Where are the highest ocean surface salinities found?
tropical central gyre The salinity of surface seawater is controlled primarily by the balance between evaporation and precipitation. As a result the highest salinities are found in the so-called sub-tropical central gyre regions centered at about 20 to 30 North and South, where evaporation is extensive but rainfall is minimal.
Is the ocean acidic or basic?
The ocean’s average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
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 is the most common dissolved constituent is seawater?
sodium chloride The most common substance dissolved in ocean water is sodium chloride.
Is coal a solution?
Coal and soil are heterogeneous mixtures and they cannot be classified as solutions.

What was the basic philosophy of the Conservative?
The conservatives favoured tradition, culture and nationally denied beliefs and customs and thought that these factors drove external changes in the society. The basic philosophy of the conservatives was they stressed the importance of tradition and established institutions and customs.
Why is sea water blue?
The ocean acts like a sunlight filter. The ocean is blue because water absorbs colors in the red part of the light spectrum. … The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water. Most of the ocean, however, is completely dark.
Why is rainwater not salty?
The heat will cause the water at the bottom of the large container to evaporate. … The salt, however, will not evaporate with the water and so, the water in the glass should taste clean. This is why rain is fresh and not salty, even if it comes from seawater.
Why is the ocean salty funny?
What elements are in the ocean?
The composition of Earth’s oceans varies from place to place. Since the oceans are mostly water, the elements hydrogen and oxygen are the most common. Sodium and chlorine are found in the salt in ocean water. Earth’s atmosphere is made up of a combination of gases, including nitrogen, oxygen, and carbon dioxide.
What element is seawater?
MINERAL MAKEUP OF SEAWATER
| ELEMENT | MOLECULAR WEIGHT | PPM IN SEAWATER |
|---|---|---|
| Chloride | 35.4 | 18980 |
| Sodium | 23 | 10561 |
| Magnesium | 24.3 | 1272 |
| Sulfur | 32 | 884 |
Is pure water an element?
Water, H2O, is a pure substance, a compound made of hydrogen and oxygen.
How is salt removed from the oceans?
Evaporation. Evaporation of isolated bodies of sea water accounts for removal of large amounts of salt from the ocean. … These minerals represent dissolved salts that have been removed from sea water by evaporation and are mined for table salt and other uses.
What are the three general components of river water?
Rivers transport three main materials downstream water, sediment, and organic material.
Which water contain more oxygen river or ocean?
Water flows into the Bay from streams, rivers and the ocean. Ocean waters generally have more oxygen. River waters are fast-moving, which helps oxygen from the air mix in.
How much salt is in a cup of ocean water?
Exercise 18.4 Salt Chuck To understand how salty the sea is, start with 250 mL of water (1 cup). There is 35 g of salt in 1 L of seawater so in 250 mL (1/4 litre) there is 35/4 = 8.75 or ~9 g of salt. This is just short of 2 teaspoons, so it would be close enough to add 2 level teaspoons of salt to the cup of water.
Why does oil not dissolve in water oceanography?
Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.
What happens when a glass of cold water is warmed to room temperature?
Which of the following is likely to happen when a glass of cold water is warmed to room temperature? … The water will absorb air as the solubility of its dissolved air increases. Small air bubbles will form as the solubility of its dissolved air decreases.
