When an ionic salt like NaCl is added to water, the ions from the salt introduced will attract the water molecules in an effort to "solvate" the ions. This has the tendency to decrease the weak affinity of non-polar oxygen molecules to water and drive the dissolved oxygen out of the polar water. In general, the solubility of a gas in a solvent is affected significantly by the presence of other solutes in the solution.
What else can I help you with?
Does lack of oxygen cause unconsciousness?
yes
What problems does salinity cause to the environment?
salt absorbs moisture from the ground this prevents plant growth also salt crystals are sharp and damage tender growth this causes erotion.
Can not getting enough oxygen make you sleepy?
Yes, not getting enough oxygen can and will make you drowsy, also, not getting enough oxygen can cause brain damage. - Heisenberg
What is the most common cause of fatalities in an oxygen deficient confined space?
asphyxiation
What gas is a major cause of chemical weathering?
I believe you're referring to sulfuric acid, which is in acid rain.
True or false dissolved oxygen in the ocean water causes salinity?
False. Dissolved oxygen in ocean water does not cause salinity. Salinity is primarily determined by the amount of dissolved salts in the water, such as sodium and chloride ions. Dissolved oxygen levels are influenced by factors like temperature, depth, and the presence of photosynthetic organisms.
Which of the following can cause a decrease in dissolved oxygen in the water?
Excessive plant debris
What can cause dissolved oxygen levels to decrease?
Dissolved oxygen levels can decrease due to factors such as high water temperature, increased organic matter or pollution, excessive plant growth leading to oxygen depletion during decomposition, and reduced mixing of water layers.
Can cause an increase in the density of the ocean water?
salt a decrease in temperature and an increasue in salinity
What can cause the increase in the density of ocean water?
salt a decrease in temperature and an increasue in salinity
What can cause an increase in density of ocean water?
salt a decrease in temperature and an increasue in salinity
What's dissolved oxygen?
Dissolved oxygen is the current amount of oxygen in the water. A certain amount of Dissolved Oxygen Is needed to keep the fish alive, if any of the dissolved oxygen decreases by either a little or a lot it can cause changes in the water, normally if the dissolved oxygen decreases so do the fish and aquatics life's life.
What can decrease the amount of dissolved oxygen in water?
Sometimes, water can become overheated, like if it is near a factory or power plant. If the water's temperature increases, then the Dissolved Oxygen (DO) level will decrease, which can cause strain or even death for many fish and marine wildlife.
What is dissolve oxygen?
Dissolved oxygen refers to the amount of oxygen present in water. It is essential for aquatic life to breathe and thrive. Factors such as temperature, water flow, and levels of organic matter can impact the amount of dissolved oxygen in water.
What condition would cause the salinity of ocean water decrease?
A river flowing into the sea is causing the decrease in salinity
What happens if there is too much oxygen in seawater?
Oxygen in the water is called "dissolved oxygen" because quite simply it is just that. The air naturally diffuses into the water and can reach equilibrium with the water. It is virtually impossible to get too much dissolved oxygen in the water because the excess will convert back to gas and bubble out of the water like so much soda water when you pour it out of the bottle. This said, there is no concern for too much dissolved oxygen in the water. Concern arises when dissolved oxygen levels get too low. When this happens more sensitive plants and animals become weak or die. As a side note, weather, temperature, and salinity all effect dissolved oxygen levels. Faster moving water contains more dissolved oxygen because it has more contact with the air than still water. Cold, fresh water holds more oxygen than warm or salty water. This would mean a cold, fast moving, fresh water stream or river would contain the highest amounts of dissolved oxygen, and the salinity of the ocean water would not be ideal for holding as much dissolved oxygen.
What is the salinity in the water that the crab live?
The salinity affects the crabs by altering the size of their internal organs, causing them to swell and decrease, as the salinity does. This drastic change in the crabs can cause death, and colour changes within the crab.
