Is there a chemical reaction between PVC and concrete?
Yes, there can be a chemical reaction between PVC and concrete, particularly in the presence of moisture. The alkaline nature of concrete can lead to degradation of the PVC material over time. This can result in the weakening of the PVC pipes or fittings in contact with the concrete. Proper insulation or protection is recommended to prevent this reaction.
What is the chemical bond of PVC?
Polyvinyl chloride (PVC) is a polymer made up of repeating vinyl chloride monomers. The chemical bond in PVC is a covalent bond between the carbon and chlorine atoms in the vinyl chloride monomers. This covalent bond is strong, giving PVC its durability and resistance to heat and chemicals.
What is the process for achieving a blue patina on brass?
To achieve a blue patina on brass, the process involves applying a solution of ammonia and salt to the brass surface and allowing it to oxidize over time. This creates a chemical reaction that results in the desired blue-green color. The brass can also be heated or treated with other chemicals to enhance the patina effect.
Does LPG have a chemical reaction with brass?
You mean like, you've got a propane tank and the brass valve is blue? That's bad, because it isn't LPG that did that. It's anhydrous ammonia, and it's very strong evidence someone's making meth. Meth makers who steal anhydrous--they can't BUY it, they have no reason to--store it in propane tanks.
Why did they use brass shavings and not brass blocks in finding the composition of brass?
Using brass shavings increases the surface area available for chemical reactions, leading to more accurate results in determining the composition of brass. This increased surface area allows for better mixing with reagents, promoting a more thorough reaction. Additionally, shavings are easier to handle and disperse evenly, ensuring that the sample is representative of the overall composition of the brass.

Is brass an ionic compound solid chemical reaction or a base?
Brass is a BASE METAL :)
Why use PVC tee with brass?
In general you would only do this if you need to connect a section of brass piping to a pvc section.
How do you connect PVC to brass?
Yes and NO depending on what kind of piping system. for drain connections yes like tub drains or fixture traps but you need access to all slip/compression fittings. and NO you can not use PVC to brass for like a discharge pipe on a waterheater PRV (pressure relief valve) or any hot water piping system
How do you conet PVC pipe to lead pipe?
Lead wipe a brass nipple into the lead pipe and then use a female adapter x PVC on the brass threads
Does burnished brass and antique brass look the same?
Burnished brass and antique brass almost look exactly the same. They are created by polishing unlacquered brass. This creates a chemical reaction that looks 'burnished' or 'antiqued'. Brass can also look like this after many years and be referred to as antique brass.
What chemical reactions will happen if you connect galvinized copper and brass metal pipes?
There is no chemical reaction that will happen if galvanized pipes are connected to copper pipes via a brass intermediary. The reason is that brass does not react to either copper or zinc, the mineral used to galvanize metal pipes.
What will get in the reaction between PVC and morpholine?
The reaction between PVC (polyvinyl chloride) and morpholine is likely to result in the formation of PVC-morpholine adducts. These adducts can improve the flexibility, thermal stability, and resistance to heat aging of PVC. The reaction is often used in the modification of PVC to enhance its properties.
How morpholine is used for PVC identification?
Morpholine can be used in the identification of polyvinyl chloride (PVC) through a chemical reaction that leads to the formation of specific derivatives. When morpholine is applied to PVC, it can cause the release of hydrochloric acid (HCl), which is a characteristic reaction of PVC. By analyzing the resulting products or observing changes in properties, such as solubility or color, morpholine aids in confirming the presence of PVC in a sample. This method is particularly useful in forensic and material analysis contexts.

How do you connect brass pipe to PVC pipe?
If the brass threaded nipple is a male end and the PVC side is a female end, wrapping thread tape around the nipple and then screwing it into the female PVC end will provide a secure and watertight connection.
