What does emulsion test detect?
The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.
Which laboratory equipment would most likely be used for testing a substance for the presence of monosaccharides?
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.
What does a substance contain if you add iodine and it turns black?
If a substance turns black when iodine is added, it indicates the presence of starch in the substance. Iodine forms a blue-black complex with starch molecules, leading to the color change. This reaction is commonly used to test for the presence of starch.
What substance does iodine solution test for?
Iodine solution tests for the presence of starch. It turns from brown to blue-black in the presence of starch.
What is thermometric substance?
These are materials used in thermometer whoses property varies with temperature
What does emulsion test detect?

Is material singular?
Yes, material is singular when referring to a singular entity or substance. For example, "The material used in this project is steel."
What is the difference between hardness and texture?
Hardness usually is used to describe the difficulty of separating the molecules of a material or substance. The texture is simply how the material or substance feels.
What turns color in the presence of strach?
In the presence of starch, iodine turns purple.
Which laboratory equipment would most likely be used for testing a substance for the presence of monosaccharides?
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.
What is iodine used as an indicator for?
Iodine is used as an indicator for starch. When a substance has iodine added to it, then it will turn into a dark blue color. This is a sign that the substance indeed has starch in it.
What is a substance used to change the colour of a other material that is a three letter word?
dye
What does a substance contain if you add iodine and it turns black?
If a substance turns black when iodine is added, it indicates the presence of starch in the substance. Iodine forms a blue-black complex with starch molecules, leading to the color change. This reaction is commonly used to test for the presence of starch.
What is material frequency?
Material frequency refers to how often a particular material or substance is used or encountered in a given context, such as in a specific industry, product design, or research material. It is used to determine the prevalence and importance of a material in a certain field.
What substance does iodine solution test for?
Iodine solution tests for the presence of starch. It turns from brown to blue-black in the presence of starch.
What substance is in sand that is used in making transistors?
Silicon is the substance in sand that is used in making transistors. Silicon is used as the raw material for producing the silicon wafers, which are then processed to create the transistors.
What is thermometric substance?
These are materials used in thermometer whoses property varies with temperature
