Account for the low pH values in the amazon river?
abnormally high levels of decomposition with low water flow makes detritus (like leaves ) turn the water brown and increase ph. The water is close to neutral in areas of high movement.
Would you expect a river to have higher PH in the summer or winter?
in the toilet season
What is the pH factor?
In chemistry, pH is a measure of the activity of the hydrogen ion. Pure water has a pH very close to 7 at 25°C. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline.
How is dolomite used with water?
Dolomite can be used in saltwater aquariums to buffer changes in pH of the water
Is the water safe to drink in South Africa?
your Absolutely right when you say 75% of the earth is made of water. But think about this: 97% of every human being on this planet is made up of water. Then take into account all other life on the planet, and your quickly running dry. Then there's the issue with different KINDS of water. We humans (and most other mammals) need to consume Fresh water. This must be within a certain Ph range and be in a certain range of saltiness. Most people think that all water is replaced using the water cycle (if you don't know what that is, google it), but the truth is most water is actually LOST during the process of evaporation. Water may not get as much attention as the energy crises, but it is indeed a major problem the next generation will have to deal with.
How does pH level affects the river?
They affect the river by changing the temperature of the water, if the pH levels are high then the water is warmer and if the pH levels are low then the water is cold.
Colour of pH paper when dipped in river water?
The pH of river water is the measure of how acidic or basic the water is on a scale of 0-14. It is a measure of hydrogen ion concentration. U.S. natural water falls between 6.5 and 8.5on this scale with 7.0 being neutral. The optimum pH for river water is around 7.4. Therefore, the color of pH paper dipped in river water would be a yellowy green around the pH of 7.4.
What has a pH range from 6-8?
Water
What is the pH range for natural water?
4 and 6
Why pH range from 0 - 14?
pH is based on the ionic product of the water. At ionic product of water reaches to 100, then the pH of the solution is 14.
Why the pH of a river sample differ after standing 1 week?
pullution change the pH of water
What is the pH of dirty water?
"Dirty" does not define any particular pH range for water. Water can be contaminated by acids, alkalis or neutral materials.
What is the pH range of mayonnaise?
The specific gravity [relative to water] is 0.91
What is the pH scale of lake water?
Most natural lake waters range from PH=6 to 9
What is the pH range in hot water?
Can be anything, there's no strong link between pH and temperature. -------------- When the temperature is increasing the pH of water is decreasing and the ionic product (Kw) is increasing; at 50 0C the pH of pure water is 6,43. See the link below for the theory and for a table of pH.
What is the pH of drinking water major cities?
Well it depends on what has been in the river.
What is the pH range of aquas solution when the gas is dissolved in water?
The pH is dependent on the gas nature, concentration, pressure and temperature.
