Add a solution of Sodium carbonate, Na2CO2, to the mixture. If it is NaCl, no noticeable rxn will take place.since the least soluble product would be Na2CO2, which is still soluble. If it is CaCl2, the product would be CaCO2 (calcium carbonate). and a precipitate would be formed, very insoluble in water.

Why is it misleading to identify a solid compound just from a lone mp determination?
A single melting point determination may not be enough to accurately identify a solid compound because different compounds can have similar or identical melting points. Additional tests such as infrared spectroscopy, mass spectrometry, or elemental analysis are needed to confirm the identity of a compound.
An unknown compound A gave the following results with spot tests?
Can you please provide the results of the spot tests for compound A?
What tests can be conducted to identify the infectious agent of meningitis?
Tests commonly conducted to identify the infectious agent of meningitis include cerebrospinal fluid analysis for cell count, protein, glucose levels, and culture, as well as polymerase chain reaction (PCR) testing to detect specific genetic material of bacteria, viruses, or fungi. Blood cultures and imaging studies such as CT scans or MRIs may also be used to help identify the source of infection.
Why is it important to carry out colour test?
Color tests are important because they can provide valuable information about the chemical composition of a substance. By observing the color change or reaction, we can deduce the presence of specific functional groups or elements in the sample. This can help identify substances, monitor chemical reactions, or assess the purity of a compound.
Would you try to identify a Gram positive coccus using the Enterotube II?
The Enterotube II is not typically used to identify Gram-positive cocci. It is primarily used to identify and differentiate Enterobacteriaceae - a family of Gram-negative bacteria commonly found in the intestines. To identify Gram-positive cocci, other tests such as catalase, coagulase, and hemolysis tests are more appropriate.

What are Coombs' tests?
Coombs' tests are blood tests that identify the causes of anemia
An unknown compound A gave the following results with spot tests?
Can you please provide the results of the spot tests for compound A?
How is the meltin point of a pure solid used in identifying it?
Since each compound has a specific melting point, knowing the melting point can narrow down the possibilities so that only a few additional tests are needed to identify the compound.
How could you identify two unknown white crystals such as salt and sugar?
If you can isolate the compound individually first, that's the best thing. Further to this, anion and cation tests will tell you what kind of salt it is. There are also tests to determine simple sugars.
Tests to identify metals?
There are many different tests that can be used to identify different metals. Using a magnet is a popular test to distinguish metals.
Why do scientists use precipitation tests?
to identify minerals
What can be accomplished by neurological tests?
Neuropsychological tests can identify syndromes associated with problems in a particular area of the brain.
What is an iki test?
It tests for the presence of starches in an organic compound..
What tests you could use to discover if a compound were ionic or molecular?
Dissolve them in water. If the solution conducts electricity, then the solute is an ionic compound. If not, then it is a molecular compound.
Is multiple choice tests hyphenated?
No, "multiple choice tests" is not hyphenated. The term "multiple choice" functions as a compound adjective describing the noun "tests," but they are typically written as two separate words when used in this context. However, if used as a compound adjective before a noun, it would be hyphenated, as in "multiple-choice tests."
Can you name the tests that scientists use to identify minerals?
hardness and streak
