a controlled substance can mean many things. it is generally a drug or chemical whose manufacture, possession, and use are regulated by a government. if you are talking about marijuana for example, in many places it is regulated in a way where little to no amount is allowed to be consumed, possessed or sold. alcohol is also controlled, but it is controlled in a way where it must be taxed and cannot be too pure. it cannot be consumed by people below a certain age.
No, Valtrex is not considered a controlled substance in most countries. It is a prescription medication used to treat herpes infections.
In the Biuret test, the control substance typically used is a solution containing a known concentration of proteins, such as bovine serum albumin (BSA). This control helps establish a baseline for comparison with the test samples, ensuring that any color change observed is due to the presence of proteins. A negative control, often a solution without proteins, may also be included to confirm the specificity of the test.
The process is called dilution. It involves adding water to a substance to reduce its concentration or strength. This method is commonly used in chemistry labs to control the concentration of solutions.
A defoaming agent is typically used to reduce bubbling in a substance. These agents work by breaking the surface tension of the bubbles, causing them to collapse and disappear. Defoaming agents can be added directly to the substance that is bubbling to help control and prevent excessive foaming.
Water is often used as a control sample because it is a neutral substance that does not interfere with the experiment. By comparing the results from the experimental samples to the control sample of water, researchers can more accurately determine the effects of the variables being tested. Additionally, water is readily available, inexpensive, and easily controlled for consistency.
no
The density of any substance is constant, we don't control it. However, by finding the density of any substance, it can be used to help identify the substance.
Usually water is the best control substance for the Sudan IV test.

Congestion control mechanisms are tools that control how backed up a substance may get. Traffic congestion control mechanisms can be stop lights, for example.
