How do you conduct the solubility test?
To conduct a solubility test, add a small amount of the substance to a test tube of solvent (such as water) and observe whether it dissolves. If it dissolves, the substance is soluble; if it does not dissolve, the substance is insoluble in that solvent. Repeat the test with different solvents to determine the solubility characteristics of the substance.
Is liquid nitrogen combustable?
No, nitrogen, whether solid, liquid, or gas, is relatively inert.
Is yellow acid or alkali?
Yellow is not a definitive indicator of whether a substance is an acid or an alkali. The color of a substance is not directly related to its pH or acidity levels. pH testing is required to determine if a substance is acidic or alkaline.
A substance that is used to determine an acid or base is called?
An indicator is a substance that is used to determine whether a solution is acidic or basic by changing color based on the pH of the solution. Examples of indicators include litmus paper, phenolphthalein, and bromothymol blue.
What is a characteristics of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
Is water soluble flammable?
Whether a substance is water soluble has little to do with whether it is flammable.

Which substance would be most appropriate to determine whether a substance contains simple sugars such as glucose?
Benedict's solution
What 2 factors determine the state of a substance?
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
What things could be used to determine whether a substance is an acid or a base?
litmus paper.
What is an experiment that can determine whether a solid white substance is a lipid or a carbohydrate?
Rub the substance on a paper bag, if it leaves a grease stain, it is a Lipid.
How can you determine whether a substance is hydrophilic or hydrophilic?
To determine whether a substance is hydrophilic or hydrophobic, you can assess its molecular structure and polarity. Hydrophilic substances typically contain polar functional groups that can form hydrogen bonds with water, leading to increased solubility in water. In contrast, hydrophobic substances are usually non-polar and do not interact favorably with water, often repelling it. Conducting a solubility test by mixing the substance with water can also provide insight; if the substance dissolves well, it is likely hydrophilic, while poor solubility indicates hydrophobic characteristics.
Is liquid nitrogen combustable?
No, nitrogen, whether solid, liquid, or gas, is relatively inert.
How does a biologist determine whether a thing is living or nonliving?
Biologists determine whether a thing is living or nonliving by a list of characteristics. These characteristics include the ability to reproduce, the ability to eat, the ability to grow and the ability to excrete waste.
How do you determine whether a given gas was nitrous oxide or nitric oxide?
nitrous oxide: At room temperature, it is a colorless, non-flammable gas, with a slightly sweet odor and taste.
