Why alkali metal is poor complexing agent?
Because alkali metal is weak oxidizing agent. complexing agent is related with reduction.
What are complexing agent?
complexing agents are ligands that are capable forming complexes with metal ions by the formation of coordinate bond
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
What is a common name for NH3?
The common name for NH3 is ammonia. Ammonia is often used as a household cleaning agent in a solution of ammonium hydroxide.

Why should excess complexing agent be avoided in gravimetric analysis?
To increase solubility product constant by complexation
What is a common name for NH3?
The common name for NH3 is ammonia. Ammonia is often used as a household cleaning agent in a solution of ammonium hydroxide.
Why group 1 element poor complexing agents?
They ease with which they donate their outermost electrons which makes them good reducing agents
Why NH3 is poor reducing agent while BiH3 is a strong redusing agent?
A good reducing agent is something that can easily lend a hydrogen atom. Nitrogens Hydrogens are in a subshell that is much closer to the nucleus of the Nitrogen atom. This smaller radius results in a greater attraction between the electrons H+ and N share. Bismuth (Bi) has a much larger radius, so the forces are more diluted, and the H+ is more easily removed from the Bi. Because the Nitrogens H+ in NH3 is harder to remove it is a mild reducing agent. Bismuth has a H+ that can be removed easily so it is a stronger reducing agent.
What is the reaction when you mix copper chloride and ammonium hydroxide?
This is an addition reaction that is also a complexing reaction. The ammonia complexes the copper and acts as a ligand. Tetra-amine Copper Chloride is formed which is a deep inky blue color. [Cu(NH3)4]2+ [Cl-]2 + 4H2O
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
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.
What molecule can form hydrogen bonds with others like it?
NH3
