Best Answer

Because the substance could potentially be extremely toxic or harmful. You must never use an unknown substance in experiments without identifying it first, many tests can be undertaken to determine the cation and anion. These tests include the flame test, solubility tests, precipitate reaction tests and conductivity tests. These do vary depending on the unknown substance.

Knowing the solubility of an unknown substance in water can help to identify what it is.?

Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.


What properties do scientists look for to identify an unknown substance?

Scientists look for properties such as density, boiling point, melting point, solubility, conductivity, and reactivity to help identify an unknown substance. By comparing these properties to known data in a database, scientists can often determine the identity of the unknown substance.


Name several properties of matter that help you identify an unknown substance?

Density, melting point, boiling point, color, odor, solubility, and conductivity are important properties of matter that can aid in identifying an unknown substance. By comparing these characteristics to known data in reference tables, scientists can determine the identity of the unknown substance.

What happens when you add sodium carbonate to an unknown substance?

Sodium carbonate can react with acidic components in the unknown substance to form carbon dioxide gas, which may result in fizzing or effervescence. This reaction can help identify the presence of acidic compounds in the unknown substance.


Why Do You Think Scientists Can Use The Basic Properties Of Matter To Help Identify An Unknown Substance?

Because if a substance can't be known then it has to prove its mass and volume


What can be used to identify an unknown substance?

Just about any property that can be observed or measured can help you reduce the number of options.


If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?

To identify an unknown substance, you would typically use its intensive properties. Intensive properties, such as density, boiling point, and specific heat, are independent of the amount of substance present and are useful for identifying specific materials.


How can density be used to determine the identity of a substancce?

Density can be used to determine the identity of a substance by comparing the density of the unknown substance to the known densities of different substances. Each substance has a characteristic density, so if the density of the unknown substance matches that of a known substance, it can help identify the unknown substance.


How you might use Rf values to identify an unknown substance?

You can compare the Rf value (retention factor) of the unknown substance to that of known substances under the same conditions. If the Rf value matches that of a known substance, it can help identify the unknown substance based on its movement relative to the solvent front on a chromatography plate.

What is meant by a characteristic property of a substance?

A characteristic property of a substance is a unique and specific attribute that is inherent to that substance and helps to identify and distinguish it from others. These properties remain constant regardless of the amount or form of the substance and can be used to determine its identity.
