Is the question whether or not the substance is water or another liquid, or is the question if the water is completely pure. Either way, the test you perform really depends a lot on what you think it might be or what impurities it might have. There are several electrochemical and spectroscopic techniques that are possible, but I can't be more specific without more information about the question.

One test that can differentiate between a solution and a pure liquid is a boiling point test. A pure liquid will have a specific and consistent boiling point, while a solution will exhibit a boiling point elevation due to the presence of solute particles. By measuring the boiling points, you can determine if the substance is a solution or a pure liquid.
Pure liquid water has a neutral pH of 7.
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.
No, the filtrate may contain dissolved solutes from the liquid being filtered, depending on the filtration method used. It is not always pure, especially if it is a solution rather than a pure liquid.
Yes Nitrogen is a pure substance because pure substances are both compounds and elements. Nitrogen is an element.

A pure liquid is a liquid that is not contaminated with any other compound. If water is pure water, then it is a pure liquid. However, shampoo is not a pure liquid.

no shampoo is not a pure liquid
Water is a pure liquid as it contains only H2O molecules. Shampoo, on the other hand, is a mixture of different ingredients including water, surfactants, fragrances, and other chemicals, making it not a pure liquid.
Pure liquid water has a neutral pH of 7.
it s pure liquid.
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.
You will have to do an experiment to find this out. You can get the proper tools and see what compounds are in both solutions.
The temperature at which a pure solid changes to a liquid is the substance's melting point.
No, the filtrate may contain dissolved solutes from the liquid being filtered, depending on the filtration method used. It is not always pure, especially if it is a solution rather than a pure liquid.
