Is barium iodide soluble?
Yes, barium iodide is soluble in water. It will dissolve and dissociate into barium ions (Ba2+) and iodide ions (I-) in solution.
How many moles of the iodide ions are present in 45.6 ml of a 4.00 x 10-3 M solution of Cobalt (II) iodide?
To find the number of moles of iodide ions in the solution, first calculate the total moles of Cobalt (II) iodide (CoI₂) in 45.6 ml of a 4.00 x 10⁻³ M solution. Moles of CoI₂ = concentration (M) × volume (L) = 4.00 x 10⁻³ mol/L × 0.0456 L = 1.824 x 10⁻⁴ moles. Since each CoI₂ produces two iodide ions (I⁻), the total moles of iodide ions will be 1.824 x 10⁻⁴ moles × 2 = 3.648 x 10⁻⁴ moles of iodide ions.
Where does the potassium go in the potassium iodide catalyst reaction with hydrogen peroxide?
In the potassium iodide catalyst reaction with hydrogen peroxide, potassium iodide (KI) dissociates in solution to provide potassium ions (K⁺) and iodide ions (I⁻). The iodide ions act as a catalyst, facilitating the decomposition of hydrogen peroxide (H₂O₂) into water (H₂O) and oxygen gas (O₂). The potassium ions remain in the solution as spectators, balancing the charge but not participating directly in the reaction. Thus, the role of potassium in this context is primarily as a counterion.
Reaction of metabisulfite with iodin?
The reaction between metabisulfite and iodine forms iodide ions and bisulfite ions. The metabisulfite reduces the iodine to iodide ions, while itself is oxidized to bisulfite ions. This reaction is commonly used as a titration method to determine the concentration of iodine in a solution.
Is potassium iodide strong weak or non electrolyte?
Potassium iodide (KI) is considered a strong electrolyte. When dissolved in water, it completely dissociates into potassium ions (K⁺) and iodide ions (I⁻), allowing it to conduct electricity efficiently. This characteristic is typical of strong electrolytes, which fully ionize in solution.
How many ions in hydrogen iodide?
Two ions: H+ and I-
How many barium ions are there in 250 mL of a barium iodide solution that has an iodide ion concentration of 0.125 M?
The number of barium ions is 0,188.10e23.
Why is Mgl2 formed by inoic bonding?
There are magnesium ions and iodide ions in magnesium iodide.
When solid sodium iodide dissolves in water what is one of the aqueous ions?
One of the aqueous ions formed when solid sodium iodide dissolves in water is iodide (I⁻).
Potassium iodide base or acid?
Potassium iodide is a salt and will dissociate into potassium ions and iodide ions in water, so it is considered a base.
What is the colour of Chlorine in its reactions with the bromide and iodide ions?
Chlorine is yellow in its reactions with bromide ions and brown-red in its reactions with iodide ions.
Is barium iodide soluble?
Yes, barium iodide is soluble in water. It will dissolve and dissociate into barium ions (Ba2+) and iodide ions (I-) in solution.
What is the name if an ionic compound that consists of lithium ions and iodine ions?
lithium iodide (LiI)
What statement correclty describe potassium iodide kl?
there is a one-to-one ratio of potassium ions to iodide ions
What happens when sodium iodide dissolves in water?
When sodium iodide dissolves in water, it dissociates into sodium ions (Na+) and iodide ions (I-). These ions are surrounded by water molecules in a process called hydration. The resulting solution will conduct electricity due to the presence of these ions.
What is the chemical formula for barium ions and iodide ions?
The chemical formula for barium ions is Ba2+ and for iodide ions is I-.
What is an example of a Halides?
fluoride, chloride ions, bromide ions, iodide ions
