Why is masking agent used during EDTA titration?
Masking agents are used during EDTA titrations to prevent interference from other metal ions that could potentially complex with the EDTA before the intended metal ion of interest. By using a masking agent, the undesired metal ions are selectively masked or complexed, allowing for accurate titration of the target metal ion without interference. This ensures that the titration results are precise and reliable.
Which smelling agent is added to LPG to detect leacks?
A chemical called Ethyl Mercaptan is added to LPG to give it a distinct odor. This odor acts as a warning sign in case of a leak, allowing people to detect gas leaks more easily.
What is the precipitating agent used to precipitate sulfate?
Barium chloride is commonly used as a precipitating agent to precipitate sulfate ions as insoluble barium sulfate. This reaction is often utilized in analytical chemistry to detect the presence of sulfate ions in a solution.
Which one is used to detect and identify the prensence of liquid or chemical agents?
A chemical agent detector is used to detect and identify the presence of liquid or chemical agents. These detectors are crucial for identifying hazardous substances in various environments, including industrial, military, and emergency response settings.
Which oxide cannot act as a reducing agent?
An oxide that has its oxidation number as +2, such as magnesium oxide (MgO), cannot act as a reducing agent because it has already lost electrons to oxygen and is in its highest oxidation state. This makes it unable to donate more electrons to reduce another species.
