What else can I help you with?
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...
What is the word equation for the reaction bromine and potassium iodide?
Bromine and Potassium iodide react to form Potassium bromide and Iodine.
What happens when silver nitrate solution is added to potassium iodide solution?
A white precipitate of silver iodide forms due to the reaction between silver ions and iodide ions, leaving potassium nitrate in solution. This reaction is a double displacement reaction and is used as a test for iodide ions.
Balance chemical equation of sodium chloride plus potassium iodide?
The balanced chemical equation for the reaction between sodium chloride (NaCl) and potassium iodide (KI) is: 2NaCl + KI → NaI + KCl. This equation ensures that there is the same number of each type of atom on both sides of the reaction.
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 reaction of sodium hypochlorite and potassium iodide?
When sodium hypochlorite (NaClO) reacts with potassium iodide (KI), it forms potassium chloride (KCl), sodium iodide (NaI), and elemental iodine (I2). This reaction can be represented by the equation: 3NaClO + 2KI → KCl + NaCl + NaI + I2.
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
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...
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.
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 reaction if ethyl iodide and potassium acetate?
Ethyl iodide will undergo an SN2 reaction with potassium acetate to form ethyl acetate and potassium iodide. This reaction involves the substitution of the iodine atom in ethyl iodide with the acetate ion from potassium acetate.
What is the word equation for the reaction bromine and potassium iodide?
Bromine and Potassium iodide react to form Potassium bromide and Iodine.
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.
