If you want less oxygen breathe it in from the water or get a fish to do it

What does high oxygen in water mean?
An oxygenated water (with a higher concentration of oxygen).
Which environment has the greater concentration of dissolved oxygen salt water or fresh water?
fresh water
What are biochemical oxygen demands?
BOD is the oxygen necessary for living organisms in a sample of water for the degradation of organic compounds.
What direction will oxygen diffuse?
Diffusion is when a molecules spread from an area of high concentration to an area of low concentration so the oxygen will move away from the other oxygen molecules that were in a high concentration to an area with a lower concentration. An example you would relate this to would be if you were to put a drop of food coloring into a glass of water.
What is BOD in chemistry?
Its full form is biological oxygen demand.Answer:The 5 day Biological Oxygen Demand (BOD5) is a measure of how much biologically usable dissolved organic material is present in a water sample. The units used are mg/liter (mg/L). The material can be eaten up bu microbes which remove oxygen in thee water. If this happens the low oxygen levels in the water make it unusable and or hazardous to fish.BOD5 is measured by putting a sample of the contaminated water in a sealed container, oxygenating it, then adding a microbial culture. The level of oxygen is measured at the end of 5 days and the concentration of organics is calculated.Companion tests include Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC)
How is a sample oxygen different from a sample of a water?
Oxygen is just O and water is H2O
What is the percent oxygen concentration if the water temperature is 10 degrees celsius and the oxygen concentration is 12 ppm?
The concentration of oxygen in water is 88,88 %.
What happens to the concentration of oxygen in the water when the sewage is added?
The concentration of oxygen decrease.
What happens to the concentration of oxygen in water when the sewage is added?
The concentration of oxygen decrease.
how does temperature affect the concentration of dissolved oxygen?
Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.
What does high oxygen in water mean?
An oxygenated water (with a higher concentration of oxygen).
How do you calculate COD value in a sample?
The COD can be estimated from the concentration of oxidizable compound in the sample, based on its stoichiometric reaction with oxygen to yield CO2 (assume all C goes to CO2), H2O (assume all H goes to H2O), and NH3 (assume all N goes to NH3), using the following formula:COD = (C/FW)(RMO)(32)Where C = Concentration of oxidizable compound in the sample,FW = Formula weight of the oxidizable compound in the sample,RMO = Ratio of the # of moles of oxygen to # of moles of oxidizable compound in their reaction to CO2, water, and ammoniaFor example, if a sample has 500 wppm of phenol:C6H5OH + 7O2 → 6CO2 + 3H2OCOD = (500/94)(7)(32) = 1191 wppm
How can pollution affect the level of oxygen in water?
The concentration of oxygen in waters decreases.
What is the product of the concentration of two minerals in water sample called?
The solubility product.
The relative concentration of water molecules in a liquid sample is called?
the water concentration or water content. It refers to the amount of water present in relation to the total volume or mass of the liquid sample. This can be measured using various methods, such as through direct measurement or using techniques like titration or spectrophotometry.
Can the calcium concentration of a sample increase over time?
Only by evaporation of the solvent (water?)
Which environment has the greater concentration of dissolved oxygen salt water or fresh water?
fresh water
