What color does starch change to in the presence of potassium iodide and sodium hyphoclorite?
Starch changes to a blue-black color in the presence of potassium iodide and sodium hypochlorite. This reaction is commonly used as a test for the presence of starch in a solution.
Sodium nitrate plus potassium iodide?
When sodium nitrate (NaNO3) reacts with potassium iodide (KI), it forms sodium iodide (NaI) and potassium nitrate (KNO3). This reaction is a double replacement reaction, where the positive ions from each compound switch places. The chemical equation for this reaction is: NaNO3 + KI → NaI + KNO3.
Does potassium iodide react with sodium carbonate?
Yes, potassium iodide would react with sodium carbonate to form potassium carbonate and sodium iodide. This reaction is a double displacement reaction where the cations and anions are exchanged between the compounds.
What is the reaction of acetone sodium hydroxide and potassium iodide?
When acetone is mixed with sodium hydroxide and potassium iodide, no significant chemical reaction occurs due to the absence of a strong oxidizing or reducing agent in the combination. The reaction is non-redox and no new compounds are formed.
Which shows the possible products of a single-replacement reaction nickel and zinc chloride chlorine and sodium potassium nitrate and lead iodide?
Nickel and zinc chloride: Nickel chloride and zinc Chlorine and sodium: Sodium chloride Potassium nitrate and lead iodide: Potassium iodide and lead nitrate
Sodium hypochlorite reaction with potassium iodide?
When sodium hypochlorite reacts with potassium iodide, the following reaction takes place: 2 NaOCl + 2 KI -> 2 NaI + 2 KCl + O2 This reaction forms sodium iodide, potassium chloride, and oxygen gas as products.
What color does starch change to in the presence of potassium iodide and sodium hyphoclorite?
Starch changes to a blue-black color in the presence of potassium iodide and sodium hypochlorite. This reaction is commonly used as a test for the presence of starch in a solution.

Which shows the possible products of a single-replacement reaction nickel and zinc chloride chlorine and sodium potassium nitrate and lead iodide?
Nickel and zinc chloride: Nickel chloride and zinc Chlorine and sodium: Sodium chloride Potassium nitrate and lead iodide: Potassium iodide and lead nitrate
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...
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
Sulfuric acid is added to the bleach and iodide solution to acidify the solution and promote the reaction between hypochlorite and iodide to produce iodine. The iodine produced is then titrated with sodium thiosulfate to determine the concentration of hypochlorite in the sample. Acidifying the solution helps in stabilizing the generated iodine for a more accurate titration.
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.
What is the reaction of Sodium bisulfite with sodium hypochlorite?
Sodium bisulfite reacts with sodium hypochlorite to form sodium chloride and sodium sulfate as products. The reaction is used to remove excess hypochlorite in water treatment processes.
What is the reaction of sodium hypochlorite and sodium bisulfite?
The reaction between sodium hypochlorite and sodium bisulfite produces sodium chloride, water, and sulfur dioxide gas. This reaction is commonly used to neutralize the bleaching effects of sodium hypochlorite in water treatment processes.
What is the chemical equation for the iodization of salts?
Iodine in the iodized salt exist as iodine salts (potassium iodide/iodate or sodium iodide/iodate).These salts are dissolved and dissociated in the organism as NaCl.
