What is difference between sea water and rainwater?
Sea water is salty due to the presence of dissolved salts like sodium and chloride, while rainwater is relatively pure and contains very low concentrations of salts. Sea water also contains various minerals and trace elements, whereas rainwater is mostly composed of water molecules. Additionally, sea water has a higher density compared to rainwater.
Can rainwater have a pH of 7?
Yes, rainwater typically has a pH slightly lower than 7, around 5.6-6.5 due to the absorption of carbon dioxide from the atmosphere. However, if rainwater is collected in a clean environment with minimal air pollution, its pH can be close to 7.
Why does it take a long time for polluted groundwater to become pure again?
Polluted groundwater takes a long time to become pure again because the contaminants need to naturally degrade or be filtered out by soil and rocks as the water moves through the ground. Additionally, the size of the aquifer, the type of contaminant, and the depth of the pollution can all affect the timeframe for purification. Treatment methods may also be needed to speed up the process.
Is a potassium dichromate a pure substance or a mixture in dissolved water?
Potassium dichromate is a pure substance in solid form. When dissolved in water, it forms a solution, which is a homogeneous mixture of potassium dichromate and water molecules.
Can hydrogen fluoride be dissolved in pure water?
Yes, hydrogen fluoride (HF) can dissolve in pure water to form hydrofluoric acid (HF). This process is exothermic and releases heat. The resulting solution is corrosive and requires caution when handling.
Is groundwater more pure than rainwater?
This depends on the zone: sometimes the groundwater is polluted or the rain water is acidic and contain particles collected from the atmosphere.
Is rainwater is pure water?
No, it is not always pure. In nature it is considered the purest form of water, which it is. However as it falls to the ground it mixes with a large number of impurities present in the air and hence becomes impure.
What to do to simulate rainwater on your plants?
The best way to simulate rain water for your plants is to use distilled water. It will provide a pure form of water which is free of chemicals found in tap water.
Is ocean water and pure water and rainwater are mixtures?
yes its made of oxygen and hydrogen
Does rainwater have vitamin B12?
No, rainwater would be pure water if it weren't for the contaminates is picks up from the air while falling.
Is ground water polluted?
It very much depends on the area; some groundwater is polluted but other groundwater is pure.
Rainwater is the purest form of water - true or false?
Yes, it is true but pure rain only I have said so because today we experience acid rains as well.
Is rainwater is pure form of water or distillted water?
It is based as salt water but then turned into pure water. 1. The ocean water evaporates into water vapor leaving all the salt and other chemicals behind 2.The water vapor turns into clouds 3.The clouds build up in water so much they rain. So yes rain water is pure
Which samples are pure water?
Samples that are pure water include distilled water, rainwater, and water that has been filtered through a reverse osmosis system. These samples do not contain any dissolved minerals or impurities.
Which is pure water rain water or distilled water?
Both rainwater and distilled water are forms of pure water as they contain minimal impurities. Distilled water is water that has been boiled and condensed, removing impurities like minerals and contaminants. Rainwater, on the other hand, can pick up pollutants from the atmosphere as it falls but is generally considered pure unless contaminated by environmental factors.
What percentage of earths water is pure?
Virtually none. Ever fresh rainwater or snow has dissolved impurities in it.
Is rainwater a poor conductor?
To produce rainwater, it first evaporates, only collecting pure water with nothing else, then it condenses into clouds, that are still made of pure water. When it becomes rain, it is still pure water, so it will not conduct electricity well. It's molecules carry no electric charge and there are no ions in solution to carry charges, so it would not be a good conductor.
