What is a highly pure sample of water is called?
This water is named ultrapure water or Kohlrausch water.
Steps to see if adding salt to water change the temperature at which it boils?
To test if adding salt to water increases the boiling point of the water, do the following: boil a sample of pure water until it boils. Measure the temperature at which the pure water boils. Take another sample of pure water and add salt to it, then boil this sample under the same conditions. Measure the temperature at which the salt water boils. If the latter temperature is higher, salt does increase the boiling point of water.
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.
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
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
A sample of a substance with pH 7?
Pure water has a pH of about 7.
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.
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.
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.

Take another sample of pure water and add salt to it, then boil this sample under the same conditions. Measure the temperature at which the salt water boils. If the latter temperature is higher, salt does increase the boiling point of water.
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.
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.
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. :)
A sample of water under study was found to boil at 102 degrees celsius at normal temperature and pressure is the water pure?
No. Pure water boils at 100 degrees Celsius or less.
