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.
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 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.
What happens when potassium iodide is added to lead II nitrate?
The first step is to change the words into the chemical formulas. Pb(NO3)2 + KI Then since there are two ionic compounds, it is going to be a double replacement reaction. This means that the two anions (negatively charged ions) will be switched in the products. So the next step is to form the chemical equation. Pb(NO3)2 + KI --> PbI2 + KNO3 The next step is to balance the equation. 1 Pb(NO3)2 + 2 KI --> PbI2 + 2KNO3 Then the next step would be to use stoichometry and convert the given grams of Lead (II) Nitrate to Potassium Iodide and the given grams of Potassium Iodide to Lead (II) Nitride. After that, you would find which one takes up more than the given amount of grams and that would be the limiting reactant.

How can I make elephant toothpaste using potassium iodide?
To make elephant toothpaste using potassium iodide, mix hydrogen peroxide with dish soap and food coloring in a container. Then, add potassium iodide to the mixture and watch as the foam erupts like toothpaste.
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?
Run an electrical current through the solution while in an electrolytic cell. This is a process called Electrolysis which causes the KI molecules to dissociate to form K+ and I- Iodide will eventually come to equilibrium with itself to get rid of the negative charge and form I2
What else do you add besides salt?
Table salt contain also potassium iodide or iodate (as a source of iodine) and an anticaking agent.
Why potassium iodate is added to potassium iodide in iodometry titration?
Iodometric titration means the titration of triiodide. Preparation of triiodide can be prepared by adding solid iodine to excess potassium iodide, however since iodine sublimes it is more difficult to weigh than potassium iodate. The triiodide would then need to be standardized with primary standard grade arsenious oxide. A better way is to weigh potassium iodate and add to a small excess of potassium iodide. The two ions (iodide and iodate) will also form the needed triiodide in an acidic environment. If the reagent is made fresh this way it can be used to standardize thiosulfate. Iodide iodate of known normality can also be used to titrate unknown concentrations of sulfite. For example, steam boiler treatment applications.
What happens if you add acid and chlorine at the same time?
Nothing
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.
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 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.
