Why is it important not to taste unknown substances that are being used during an experiment?
The substance may be poisonous.
What is the purpose of adding an indicator to an unknown solution?
Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
What is meant by a mixed melting-point determination?
"Mixed melting point determination" is a term used in chemistry. Organic substances have a fixed temperature at which they liquify. If a chemist wants to determine the nature of an unknown substance, he can determine it by these means. If the unknown substance does not melt at the usual temperature, it can be said to be impure. If the chemist has two unknown substances and wants to determine what they are, he may mix equal parts of each and start the liquification process. If the combination melts at the usual temperature, the chemist can say that both are the same. If the chemist wants to determine the nature of an unknown substance, he may mix a fixed amount of a known substance with a fixed amount of an unknown substance, it can be estimated, what the unknown substance is.
What 5 industries or organizations that employ analytical chemists to identify unknown substances?
That company that makes fruit shoots because they are so goddamn delicious.

When you are measuring the melting point of a mixture which consists of two unknown substances how can you find out what substances does the mixture consists of?
heat it
How do I know if it's a sperm stain or something else?
Unknown substances can be analysed by a chemist.
Knowing the solubility of an unknown substance in water can help to identify what it is.?

Why you can separate a mixture without any change in the identity of the substances?
Why a mixture can be seperated without any changes in the identity of the substance is unknown publicly. However, it is known that the seperation of these substances usually involve the process of mechanical filtering or decanting.
Why are solubility tests helpful to determine unknown substances?
A simple solubility test can be used to identify an unknown substance. Most substance will make a precipitate when around certain molecules.
