Its endothermic...
In my experiment, it went from 26 to 25 degrees celsius...

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.

∙ 11y agoYes, dissolving KClO3 in water is an endothermic reaction. I remember doing this back in 1967, and I remember being startled by the thin film of condensation of water on the outside of the test tube, along with the sudden drop in temperature of the solution.

∙ 13y agoit's exothermic because the q (heat) value is negative.

∙ 9y agopotassium chloride in water is a endothermic reaction.An endothermic reaction is any chemical reaction that absorbs heat from its environment.

it becomes hotter, therefore exothermic.
What is the reaction between bleach and potassium iodide?
the reaction between bleach anb potassium iodide is KI+NaCl2--->KCl2+NaI
Lead and potassium iodide equation?
No reaction.
What is the precipitate of lead nitrate and potassium iodide?
In the reaction: Lead (Ⅱ) Nitrate + Potassium Iodide → Potassium Nitrate + Lead (Ⅱ) Iodide.. all nitrates are soluble and lead(ii)iodide is insoluble.

Bromine and Potassium iodide react to form Potassium bromide and Iodine.
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.

No, reaction
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than the lattice energy of rubidium iodide because lattice energy is inversely proportional to atomic radius.
Write word equations to descrbe the reaction silver iodide and potassium acetate?
There is no reaction, because silver iodide is very insoluble.
Would a reaction occur if you mixed potassium chloride with iodine?
No - there would be a reaction though if Chlorine and Potassium Iodide were mixed
