What is the formula for phosporus tri-iodide?
Phosphorus tri-iodide refers to Phosphorus(III) Iodide, with formula PI3
Why potassium thiocyanate is added in the titration of sodium thiosulphate with copper?
On addition of the KI to your copper (II) solution, you formed Copper (I) iodine solid and produced the tri-iodide ion. It is the tri-iodide ion that you are titrating with the sodium thiosulfate. The tri-iodine ion is what itercalates into the starch molecules to form the dark blue color you are using as an end point in the titration. Some the the tri-iodide ion formed will adsorb to the surface of the solid copper (I) iodine formed. This must be desorbed for a complete titration. The addition of the potassium thiocyanate, displaces the adsorbed tri-iodine ion, and liberates it for titration.
Name the following compounds SnI4 N2O3 PCl3 and CSe2?
SNI4=Stannic Iodide/TIn (VI) Iodide N203=Nitrogen tri oxide PCl3=Phosphorus tri chloride CSe2=Carbon deselenide
What is a tri-positive ion?
A tri-positive ion is an ion that has a charge of +3, meaning it has lost three electrons. These ions are typically formed by elements that can easily lose three electrons to achieve a stable electron configuration.
In the covalent compound C3H6 the Greek prefix used to represent the cation is?
tri
What is the name of I3?
I3- is known as the triiodide ion (or sometimes tri-iodide ion, for better readability). It arises in equilibrium when elemental iodine (I2) and the iodide ion (I-) are both present.
What is the name of an iodine ion?
An iodide ion is an iodine atom with a −1 charge. Compounds with iodine in formal oxidation state −1 are called iodides. This can include ionic compounds such as caesium iodide or covalent compounds such as carbon tetraiodide.
Why is KSCN used in iodometry of copper?

Is carbon bromide soluble in water?
All four carbon bromides (mono-, di-, tri- and tetra-Bromomethane) are insoluble or immiscible with water.
Why do we rinse the leaf I water?
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.

What is AlI3 in chemistry?
Aluminum (III) Iodide the aluminum uses it's +3 oxidation state therefore it is named Aluminum (III) and since it is ionic the Iodine just uses Iodide
