What colour is the precipitate formed when sodium hydroxide reacts with potassium iodide?
They are not soluble, therefore they do not precipitate or form a color....a.k.a....no reaction...
Colour of aqueous iron 2 sulphate before potassium iodide is added?
The color of aqueous iron(II) sulfate is typically pale green. When potassium iodide is added, it reacts with iron(II) ions to form a dark brown precipitate of iron(II) iodide.
When chlorine is added to potassium iodide solution the colour changes from colourless to a dark reddy brown why does this happen?
The dark red-brown color change occurs because the chlorine oxidizes iodide ions to form iodine, which reacts with excess iodide ions to form triiodide ions. These triiodide ions absorb light in the visible range, resulting in the dark red-brown color observed in the solution.
What is the color of the flame of potassium iodide?
The flame of potassium iodide is typically violet or purple in color.
Why test sodium peroxoborate with sulphuric acid and potassium iodide?
Sodium peroxoborate is tested with sulfuric acid and potassium iodide to determine the presence of peroxides. When sodium peroxoborate reacts with sulfuric acid and potassium iodide, oxygen gas is released, causing iodine to be liberated from the potassium iodide. The presence of iodine can be observed by a color change from clear to brown or blue-black due to the formation of iodine.

What colour change is seen when excess potassium iodine is reacted with chlorine?
When excess potassium iodide is reacted with chlorine, the solution changes from colorless to dark brown due to the formation of Iodine (I2). Excess potassium iodide reacts with chlorine to form iodine, which imparts the dark brown color to the solution.

Why chlorine turns moist starch iodide paper blue?
Chlorine gas reacts with the potassium iodide in the moist starch iodide paper to produce potassium chloride and iodine. The iodine then reacts with the starch in the paper to form a blue complex. This color change is used as a test for the presence of chlorine gas.
How does ferric chloride reacts with potassium iodide solution?
When ferric chloride (FeCl3) is added to a solution of potassium iodide (KI), it reacts to form iron(III) iodide (FeI3) and potassium chloride (KCl). The iron(III) iodide produced is a brownish-red color, indicating the presence of the Fe3+ ion. This reaction can be represented by the following chemical equation: 2FeCl3 + 6KI -> 2FeI3 + 6KCl
What happens to potassium iodide when it gets oxidised?
When potassium iodide is oxidized, it forms iodine. Potassium iodide loses electrons hence it is oxidized. This reaction can be observed by the change in color of the solution from colorless to brown/yellow due to the formation of iodine.
What is the Reaction of iron sulphate with potassium iodide?
When iron sulfate reacts with potassium iodide, a double displacement reaction occurs where potassium sulfate and iron(II) iodide are formed. The balanced chemical equation for this reaction is FeSO4 + 2KI → FeI2 + K2SO4. This reaction is characterized by a color change from yellow (iron sulfate) to brown (iron(II) iodide).
What is the reaction between bleach and potassium iodide?
When bleach is mixed with potassium iodide, it undergoes a redox reaction. The bleach oxidizes the iodide ions to produce iodine, which can be observed as a brown color. This reaction can be used to test for the presence of bleach in a solution.
What is the colour of the endpoint for sodium hypochlocrite and potassium iodide?
The endpoint color of sodium hypochlocrite and potassium iodide is not listed.
