What happens to the concentration of oxygen in water when the sewage is added?
The concentration of oxygen decrease.
Why is sewage mixed with air?
Sanitary sewage is treated in plants that mix the raw sewage with bacteria to consume the waste materials. The nature of these bacteria is that they need oxygen to live and grow (they are aerobic bacteria). The plant equipment mixes air into the sewage to increase the transfer of oxygen to the water at much higher rates than quiescent conditions. A an added advantage this mixes the bacteria and sewage so that the bacterial population is much higher and the treatment much faster. The "full" bacteria are separated from the clean water which is discharged to surface watercourses.
What happens if water is added into alcohol?
You get a mix of alcohol and water You get dull beer.
What happens when carbon dioxide is added to a fire?
When carbon dioxide is added to a fire, it displaces oxygen, which is necessary for the fire to burn. This can help extinguish the fire by removing the oxygen fuel source.
What happens to the hydroxide ion concentration in water when a base is added?
No. A base decreases the amount of hydronium, and increases the amount of hydroxide.
When more solvent is added to a solution what happens to the concentration?
When more solvent is added to a solution, the concentration of the solute decreases. This is because the total volume of the solution increases while the amount of solute remains constant, resulting in a more diluted solution.
Why does a septic tank stink?
Because it contains sewage. It may need to be pumped out, or bacteria may need to be added to help digest the sewage.
What happens to an elodea leaf when added a phenol red solution?
When an Elodea leaf is added to a phenol red solution, the leaf will release oxygen through photosynthesis. The oxygen will cause the phenol red solution to change color, indicating the presence of oxygen production.
What happens when HCl is added to NaCl?
the concentration of Cl- increase (common ion), but the pH of the solution remain same.
What happens to the atmosphere during cellular respiration?
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
What happens during the proceess of photsytheies?
Water is split into hydrogen & oxygen, the hydrogen is added to CO2 (to make sugar) and the O2 is discarded.
What happens when iron is added to oxygen?
Nothing unless they are heated. If they are heated it will become iron oxide. Which is the same material that we find the ground
