What does dissolve oxygen mean in chemistry?
Dissolve oxygen is a type of chemical reaction in which one gas is dissolved into a liquid. In aqueous solutions, oxygen is the most common gas dissolved into water. The water can absorb as much as 20 times more oxygen than the same amount of water will allow air to do.
What does dissolved oxygen mean in chemistry?
What is dissolved oxygen? Dissolved oxygen is a chemical element that is present in water. Many natural processes turn oxygen into dissolved oxygen, including photosynthesis, decomposition, and the respiration of plants and animals. Dissolved oxygen is also produced by some mechanical processes as a byproduct, like boiling, filtering and aeration.
What is dissolved oxygen in water mean?
Dissolved oxygen (DO) refers to the oxygen present in water, whether in lakes, rivers, oceans or groundwater. It can have a major impact on the health of aquatic life and the environment. Low levels of dissolved oxygen (hypoxia) can be dangerous to living organisms, while high levels (hyperoxia) can cause mass die-offs.
What does dissolved oxygen mean in chemistry class?
Dissolved oxygen refers to the oxygen that is present in water, whether it is in ponds, rivers or the ocean. This refers to the amount of oxygen gas that is present in water, rather than the amount of oxygen bound to other chemicals, such as H2O or OH-. The most common water on earth contains around 4 mg of dissolved oxygen per liter of water.
What does dissolve other mean in chemistry?
Dissolve does not only mean that particles are mixed together. It also implies that the substances are combined or chemically bonded together. This is usually not the case with particulate matter. For example, if you dissolve sand in water, the sand grains do not chemically bond with the water. While the sand particles are suspended in the water, they do not change their physical properties.
