This is wrong it is exothermic. Potassium chloride is snow salt. it is used because not only does it react with the snow to create hydrochloric acide and potassium hydroxide (both with much lower freezing points) but, the EXOTHERMIC reaction also helps melt the snow
No, it is endothermic. The only reason we add salt to snow is to lower the melting point. If you're curious, dissolve as much KCl in a beaker as you can as quickly as you can. The water temperature will drop dramatically.
What else can I help you with?
What is the word equation for the reaction bromine and potassium iodide?
Bromine and Potassium iodide react to form Potassium bromide and Iodine.
Is the dissolution of lithium iodide endothermic or exothermic?
The dissolution of lithium iodide is typically exothermic because more energy is released when the bonds in the solid lithium iodide are broken than is required to break the bonds between water molecules.
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 happens when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube?
A yellow precipitate of lead iodide is formed due to the reaction between potassium iodide and lead nitrate. This reaction is a double displacement reaction, where the potassium from potassium iodide swaps places with the lead from lead nitrate, forming the insoluble lead iodide.
Iron plus potassium iodide?
When iron reacts with potassium iodide, it forms potassium iodide. The reaction can be written as 2Fe + 2KI → 2K + 2FeI. Potassium iodide is a salt and is commonly used as a nutritional supplement.
What will produce if HCl react with potassium iodide?
In a water, potassium iodide, What_happens_when_you_react_potassium_iodide_with_hydrochloric_acidsolution, heat is absorbed and an endothermic reaction occurs. No physical changes.
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 reaction between silver nitrate and potassium iodide?
The reaction between silver nitrate and potassium iodide forms silver iodide precipitate and potassium nitrate. This reaction is a double displacement reaction where the silver ions from silver nitrate switch places with the potassium ions in potassium iodide.
Is the dissolution of lithium iodide endothermic or exothermic?
The dissolution of lithium iodide is typically exothermic because more energy is released when the bonds in the solid lithium iodide are broken than is required to break the bonds between water molecules.
What is the word equation when potassium reacts with iodine?
The word equation for the reaction between potassium and iodine is: potassium + iodine → potassium iodide.
What happens when potassium iodide react with lead nitrate?
When potassium iodide reacts with lead nitrate, a double displacement reaction occurs. The potassium ion and the lead ion switch places to form potassium nitrate and lead iodide. This reaction results in the formation of a yellow precipitate of lead iodide.
