What is a highly pure sample of water is called?
This water is named ultrapure water or Kohlrausch water.
What is the most important type of intermolecular forces between molecules in a sample of pure water?
Hydrogen bonding
What is the full name of the separation technique to obtain pure water from sea water?
simple distillation
Is yellowish clear and odorless water an example of pure water?
no, pure water is absolutely clear. it doesnt have any color whatsoever. if there is a yellowish color, it means there are impurities in the sample.
Is pure water a compound or a mixture?
Pure water is a compound of hydrogen and oxygen.
How is a sample oxygen different from a sample of a water?
A sample of oxygen is a pure gas composed of oxygen molecules (O2), while a sample of water is a liquid composed of hydrogen and oxygen atoms (H2O). These substances have different physical properties and chemical compositions, with oxygen being a gas and water being a liquid at room temperature.
What is a highly pure sample of water is called?
This water is named ultrapure water or Kohlrausch water.
Is soda water a pure mixture?
No. Pure water is a compound and therefore a pure substance
Why do properties of a pure substance do not vary from sample to sample?
The properties of a pure substance do not vary from sample to sample because there is no reason for them to. Why would they? Water is water, and if you take any sample of water from any stream, lake or ocean and remove all the "stuff" in it to leave only the water, all the samples will behave the same way physically and chemically. The chemical properties of a substance (and the physical ones, too) are set by what the substance is. And these properties define the way the substance behaves in the universe as a whole. There is no reason for any water found on, say Mars, to behave any differently than any water here on Earth - or anywhere else in the universe.
What is the function of methylene blue solution on polluted water samples?
Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.
What purpose is is served when water is used instead of a sample substance?
For example to establish a zero point for an instrument or to make a measurement on water considered as a pure sample.
Why is saltwater considered a mixture?
Salt water is a mixture and not a pure substance. We define pure substances as those that contain atoms or molecules of the same type. Examples of pure substances are elements (such as iron, silver, gold, etc.), compounds (such as water, sodium chloride, etc.), etc. A pure substance has a uniform composition. In comparison, a mixture does not have a uniform composition of its constituents and can be divided into them by simple physical means. Salt water does not have a uniform composition and we can divide salt and water by simple physical process of evaporation (by boiling the salt water). Thus, salt water is a mixture, with salt as the solute and water as the solvent. In fact, salt water is a homogeneous mixture and can be termed as a solution.
What is a sample of a matter either single element or a single compound that has a definite chemical and physical properties?
a pure substance. :)
How will you determine that a given sample of water is pure or polluted?
To determine if a sample of water is pure or polluted, you can conduct physical, chemical, and biological tests. Physically, you can assess clarity, color, and odor. Chemically, you can test for contaminants such as heavy metals, pesticides, or excess nutrients using methods like spectrophotometry or chromatography. Biologically, analyzing for harmful microorganisms or pathogens through microbiological assays will provide insight into the water's purity.
What test do you apply to sea water to become pure water?
simple distillation
Which will freeze faster pure water or or a mixture?
Pure water will freeze at a higher temperature than a mixture containing water. Therefore, if a means for extracting energy from a sample of pure water is the same as a means for extracting energy from a sample of a mixture containing water, the pure water will freeze first.
Why are milk and fruit juices not considered pure substances?
They are aqueous solutions of various compounds in water, so they consist of many separate pure substances. Many of these can be separated by simple physical means (filtering, evaporating, centrifuge).
