A polarimeter or a refractometer would most likely be used for testing a substance for the presence of monosaccharides. These instruments can measure the rotation of polarized light or refractive index, which can help identify the presence of monosaccharides in a solution.
To test the presence of fluoride in water, you can use a fluoride test kit that contains indicators that change color in the presence of fluoride ions. Alternatively, you can send a water sample to a laboratory for more detailed analysis using specialized equipment such as ion chromatography or spectrophotometry.
Yes, the presence of another substance can affect the rate of diffusion. Factors like the nature of the substance, concentration gradient, temperature, and molecular size can influence how quickly a substance diffuses in a system.
The blue color of a laboratory flame is due to the presence of trace amounts of metal ions such as copper or cesium in the flame. These metal ions emit light in the blue part of the spectrum when they are heated in the flame.
Benedict's solution is used to test for the presence of reducing sugars in a solution, particularly glucose and other monosaccharides. It changes color when heated in the presence of reducing sugars, with a positive result indicated by a color change from blue to green, yellow, orange, or red, depending on the amount of reducing sugar present.
An indicator is a substance that changes color in response to the presence of specific substances in a solution. Litmus is a common indicator that changes from blue to red in the presence of an acid and from red to blue in the presence of a base. This color change helps to identify the nature of the solution being tested.
A variety of materials can be used for this purpose, including litmus paper, chemical reagents, chromatography paper, and spectrophotometers. These materials react in specific ways when exposed to certain substances, allowing for detection and identification.

combustion
This is the burning of a substance in the presence of oxygen.

Assays is a procedure to analyze or quantify a substance in a sample to determine the presence and amount, as well as the potency. The fields that involve the use of assays are environmental biology, laboratory medicine, pharmacology, and molecular biology.
Yes, cheese is a substance. The definition of a substance is "the real physical matter of which a thing consists and that has a solid, tangible presence."
