You put two or more materials together. If you notice changes such as increasing temperature, or appearance of a precipitate, or smoke, or changes in color, this means that those materials react together and make a chemical reaction.
You do that either by normal mixing or by heat...etc and wait for a specific time to see the changes.
In short: tests occur under strict control and adjustment of laboratory conditions.

∙ 12y agoOne way would be to dissolve them in water. Ionic compounds will break into ions and allow the solution to conduct an electric current, whereas covalently bonded substances will not.
Another way would be to find the substance's melting point. Ionically bonded compounds have much higher melting points.

When testing for chemical properties of a substance will one test be enough?
For the safety of findings it is recommended to do more tests.
Which substance in plants and animals could be examined for radioactivity to test his hypothesis?
The substance in plants and animals that could be examine for radioactivity to test its hypothesis in the cell of the plant or animal.
Why is tap water being used as a test substance?
Why is tap water being used as a test substance
What does litmus mean?
a litmus tells us if a substance is acidic or alkaline an acid will turn red litmus paper blue and an alkali will turn blue litmus paper red. if an unknown substance is tested with litmus and the colour did not change, then the substance is said to be neutral or it can be simply water. note that water is needed for acids to show its acidic properties........
What substance does Iodine test for?
carbohydrates, for one

How could you test an unknown compound to determine if it was ionic or covalent?
Conductivity is the easiest way. Ionic compounds conduct electricity in water
How would martel quickly test the Powdery substance in the bowl to determine if it had properties similar to those of the original seawater?
color change
Why substance stick to the test tube?
The ability of a substance to stick on inside part of a test tube depends on its surface tension, that's why substances such as water can stick to a window. And the other reason for sticking of a substance to the test tube could be that the test tube itself is dirty, thus the dirt particles hold the substance in place.
Can you fail a military drug test after smoking pep spice?
No, pep spice has no properties that would make it a dangerous substance, so it is not tested for.
What other substance could trigger a positive test for methamphetamines?
Adderol, ritalin or ecstasy.
How can the chemical properties of a substance be determined?
test its solubitlity by seeing if it dissolves in a solution
Why is it important for scientists to test rain forest plants?
Because a lot of them hold medicinal properties that could be used in pharmaceuticals. They also test them for pollution.
How are a solution and a substance similar?
A substance is any chemical you might have or want to test. A solution is when that substance is dissolved in water. Chemists make solutions, especially with ionic compounds, so they can break apart into their constituent components and react with something else. Water molecules, which are highly polar attract the positive and negative charges the compounds or elements that make up the ionic compound. Solutions are also good for other chemical reactions though, too.
Are substance considered reducing fehlings test also the substance reducing in benedicts test?
yes.
Color hardness texture and taste are properties of matter A. chemical B.physical C. ionic D. volumetric?
Physical matter, of course. :) Saying this cause I just took a bio test. Good luck. x
