Add an excess of potassium iodide to copper sulphate solution how much is excess?
The amount of excess potassium iodide depends on the stoichiometry of the reaction between potassium iodide and copper sulfate. One equivalent of potassium iodide is needed to react with one equivalent of copper sulfate. Excess potassium iodide would be any amount added beyond this stoichiometric ratio.
When you add lead nitrate and Potassium Iodide and filter them what is the solid?
The solid formed when adding lead nitrate and potassium iodide and filtering the mixture is lead iodide. Lead iodide is a yellow precipitate that forms by the reaction between lead nitrate and potassium iodide.
What happens when you add potassium carbonate to cobalt chloride?
When you add potassium carbonate to cobalt chloride, a double displacement reaction occurs. Potassium carbonate reacts with cobalt chloride to form potassium chloride and cobalt carbonate. The cobalt carbonate will likely precipitate out of solution as a solid.
Why is it inadvisable to add acid to your diluted bleach before adding the iodide?
Mixing acid with bleach can produce toxic chlorine gas. Adding iodide to bleach can also produce toxic fumes. Therefore, combining the two reactions could result in the production of a harmful mixture of gases, posing a serious health risk.
What happens when potassium iodide is added to lead II nitrate?
When potassium iodide is added to lead II nitrate, a double displacement reaction occurs. This reaction forms insoluble lead II iodide as a yellow precipitate and potassium nitrate as a soluble salt. The net ionic equation for this reaction is Pb2+ (aq) + 2I- (aq) → PbI2 (s).
Add an excess of potassium iodide to copper sulphate solution how much is excess?
The amount of excess potassium iodide depends on the stoichiometry of the reaction between potassium iodide and copper sulfate. One equivalent of potassium iodide is needed to react with one equivalent of copper sulfate. Excess potassium iodide would be any amount added beyond this stoichiometric ratio.

The solid formed when adding lead nitrate and potassium iodide and filtering the mixture is lead iodide. Lead iodide is a yellow precipitate that forms by the reaction between lead nitrate and potassium iodide.
What is the ionic charge of potassium iodide.?
The ionic charge of potassium iodide is determined by the groups of the elements. Potassium is in the 1st column of the periodic chart, so it is group 1, and forms a +1 cation. Iodine is a halogen (group 7) and will add an electron to fill its shell with 8 electrons, so its charge is -1.
How do you make iodine from potassium iodide?
To make iodine from potassium iodide, you can add an oxidizing agent like hydrogen peroxide to a solution of potassium iodide. This will cause the iodide ions to oxidize into molecular iodine, which will precipitate out of the solution. The iodine can then be collected and purified through further chemical processes.
What else do you add besides salt?
Table salt contain also potassium iodide or iodate (as a source of iodine) and an anticaking agent.
What happens if you add acid and chlorine at the same time?
Nothing
Why potassium iodate is added to potassium iodide in iodometry titration?
Potassium iodate is added to potassium iodide in iodometry titration to provide a more stable source of iodine in the reaction. This ensures that the reaction proceeds reliably and accurately, as potassium iodate releases iodine more consistently than potassium iodide. This helps to improve the precision and reliability of the titration results.
When add nitrous acid to potassium iodide solution?
When nitrous acid is added to a potassium iodide solution, a redox reaction occurs where the nitrous acid is reduced to nitrogen gas and iodide ions are oxidized to iodine. This reaction can generate iodine, which can be observed as a color change in the solution from colorless to brown/yellow due to the formation of elemental iodine.
How do you prepare nesslers reagent?
To prepare Nessler's reagent, dissolve 7g of mercuric iodide and 35g of potassium iodide in distilled water, and then add 100g of potassium hydroxide pellets. Once the solution is clear, dilute it with water to make 1 liter of Nessler's reagent. This reagent is commonly used for detecting ammonia in solutions.
What happens when you add potassium carbonate to cobalt chloride?
When you add potassium carbonate to cobalt chloride, a double displacement reaction occurs. Potassium carbonate reacts with cobalt chloride to form potassium chloride and cobalt carbonate. The cobalt carbonate will likely precipitate out of solution as a solid.
Why is it inadvisable to add acid to your diluted bleach before adding the iodide?
Mixing acid with bleach can produce toxic chlorine gas. Adding iodide to bleach can also produce toxic fumes. Therefore, combining the two reactions could result in the production of a harmful mixture of gases, posing a serious health risk.
What is the difference between starch solution and iodine solution?
Starch solution is a solution of starch in water, typically used to detect the presence of iodine. Iodine solution is a mixture of iodine and potassium iodide in water, used as an indicator for the presence of starch. In other words, starch solution contains starch and iodine solution contains iodine.
