Potassium bromide (KBr) is water soluble, when met with water it will dissolve. The dissolution of KBr in water is an endothermic reaction, the enthalpy change is about +19.8 Kj/mol.
Does anyone know why the solution process occurs even though the enthalpy is a relatively high positive number which should mean weaker bonds?
What else can I help you with?
What are the observations when chlorine reacts with potassium bromide?
When chlorine gas reacts with potassium bromide, the chlorine will displace bromine in the compound forming potassium chloride and bromine gas. The color of the mixture will change from colorless to reddish-brown due to the formation of bromine gas.
What is the Reaction between fluorine and potassium bromide?
When fluorine reacts with potassium bromide, the fluorine displaces bromine from the compound to form potassium fluoride and bromine gas. This is a redox reaction where fluorine is reduced and bromine is oxidized.
When a potassium atom reacts with a bromine atom the potassium atom will?
lose only one electron
When a potassium atom reacts with bromine the potassium atom will?
lose one electron to form a potassium ion with a +1 charge.
Potassium iodide reacts with bromine forming potassium bromide plus iodine?
The reaction between potassium iodide and bromine produces potassium bromide and iodine. This is a redox reaction where bromine gets reduced to bromide ions, while iodide ions get oxidized to form elemental iodine. The balanced chemical equation for this reaction is 2 KI + Br2 → 2 KBr + I2.

Chlorine gas reacts with pottassium bromine yielding potassium chloride and liquid bromine?
The reaction between chlorine gas and potassium bromide results in the formation of potassium chloride and liquid bromine. The balanced chemical equation for this reaction is 2KBr + Cl2 -> 2KCl + Br2.
Which elements are in KBr?
The elements in this formulae are Potassium (which is a metal which reacts with water on contact) and bromine ( which is a non-metal that is a liquid at room temperature).
What compound is made in the reaction between bromine and potassium?
The compound made in the reaction between bromine and potassium is potassium bromide (KBr). Bromine reacts with potassium to form a white crystalline solid compound.
What are the observations when chlorine reacts with potassium bromide?
When chlorine gas reacts with potassium bromide, the chlorine will displace bromine in the compound forming potassium chloride and bromine gas. The color of the mixture will change from colorless to reddish-brown due to the formation of bromine gas.
Why potassium (K) reacts easily with bromine (Br)?
Potassium reacts easily with bromine because potassium's outer electron shell has only one electron, making it highly reactive and able to readily form a bond with bromine. Bromine, on the other hand, has a strong tendency to gain one electron to achieve a stable electron configuration. This combination of factors leads to a quick reaction between potassium and bromine.
What is the Reaction between fluorine and potassium bromide?
When fluorine reacts with potassium bromide, the fluorine displaces bromine from the compound to form potassium fluoride and bromine gas. This is a redox reaction where fluorine is reduced and bromine is oxidized.
Why does bromine react with potassium?
Bromine reacts with potassium because it is a more reactive halogen than bromine. Potassium will readily donate an electron to bromine to form an ionic compound (potassium bromide) in order to achieve a more stable electron configuration. This reaction is typically vigorous and exothermic.
What happens when potassium reacts with water and oxygen?
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.
When a potassium atom reacts with a bromine atom the potassium atom will?
lose only one electron
When a potassium atom reacts with bromine the potassium atom will?
lose one electron to form a potassium ion with a +1 charge.
What is the reaction between potassium astatine with bromine?
When potassium astatine reacts with bromine, it forms potassium bromide and astatine. The reaction is likely to be quite vigorous due to the high reactivity of astatine and the relative electronegativity difference between the two elements.
