Why alkali metal is poor complexing agent?
Because alkali metal is weak oxidizing agent. complexing agent is related with reduction.
What is the name of the complexing agent used to determine the total hardness?
caco3
What is the full name of the complexing agent used to determine the total hardness?
caco3
Why nh3 is good complexing agent?
it has a LONE pair of electrons that is sterically unhindered
What is the purpose of an auxiliary complexing agent in an EDTA titration of a metal ion?
The purpose is for the agent to "bind to a metal strongly enough to prevent metal hydroxide from precipitating, but weakly enough to give up the metal when EDTA is added." -Quantitative Chemical Analysis, 8th edition, Daniel C. Harris

Why should excess complexing agent be avoided in gravimetric analysis?
To increase solubility product constant by complexation

What is a chelating agent for pools?
A chelating agent (also known as a complexing or sequestering agent) is a compound that forms stable complexes with metal ions. Control of metal ion activity in aqueous systems is the main use of chelating properties so precipitation of sparingly soluble salts such as those of of calcium and magnesium with inorganic anions, fatty acids and anionic surfactants can be avoided. Typical applications are scale control and water softening.
Why resorcinol is used as a reagent in test in seliwanoff test?
Resorcinol is used as the complexing agent to provide the color reaction, although the exact nature of the colored product is not known. Since resorcinol favors electrophilic aromatic substitution, the reaction may be similar to the Molisch Test.
Why group 1 element poor complexing agents?
They ease with which they donate their outermost electrons which makes them good reducing agents
Why are stannic halides rendered more inert by complexation?
The complexing "agent" changes the level of ionisation of the stannic halide. This makes it less likely to react with another ionic compound. The stannic halide itself also alters the pull/push of radicals (in this case P) attached to the carbon rings (Ph) in the complex as well.
What is the diffrenece between a physical change and a chemical change?
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
How many agents are in Lego agents?
Agent Fuse, Agent Chase, Agent Swift, Agent Swipe, Agent Trace, Agent Alan and Agent Dmetrie.
