What is the combining ratio of potassium and bromine?
The combining ratio of potassium and bromine is 1:1, meaning that one atom of potassium combines with one atom of bromine to form potassium bromide (KBr).
What do you get if you react potassuim with cold water?
potassium hydroxide
Simple distinguished test between saturated and unsaturated compounds?
One simple test to distinguish between saturated and unsaturated compounds is the bromine water test. Saturated compounds do not react with bromine water (no color change), whereas unsaturated compounds will decolorize the bromine water due to addition of bromine across the double bond in the unsaturated compound.
Why Kerosene does not decolourise bromine water while cooking oils do.?
Kerosene does not decolourise bromine water because it is a saturated hydrocarbon, meaning it lacks double or triple bonds that can react with bromine. In contrast, cooking oils contain unsaturated fatty acids, which have carbon-carbon double bonds. These double bonds can react with bromine, leading to the decolourisation of the bromine water as it forms brominated compounds. Thus, the presence of unsaturation in cooking oils is the key factor in this reaction.
Why does on aqueous solution of iodine will not react with an aqueous solution of potassium bromide.?
An aqueous solution of iodine (I₂) will not react with an aqueous solution of potassium bromide (KBr) because iodine is less reactive than bromine in terms of oxidation potential. In this case, iodine cannot oxidize bromide ions (Br⁻) to bromine (Br₂), as bromide is a stronger reducing agent. Therefore, no reaction occurs between the two solutions.
Does bromine water react with potassium chloride?
Yes, bromine water (Br2) will react with potassium chloride (KCl) to form potassium bromide (KBr) and chlorine gas (Cl2) as products. This reaction typically involves the displacement of bromine by chlorine in the compound.
Will chlorine and potassium bromide react?
Yes, chlorine will react with potassium bromide to form potassium chloride and bromine. This is a displacement reaction where the more reactive chlorine displaces bromine from potassium bromide.
What is the word equation for the reaction bromine and potassium iodide?
Bromine and Potassium iodide react to form Potassium bromide and Iodine.
What react with potassium?
all of the halogens: bromine, fluorine, oxygen, chlorine and iodine. and it is highly reactive with water.
Why bromine does not react with aqueous potassium chloride?
Bromine does not react with aqueous potassium chloride because it is less reactive than chlorine. Chlorine is more electronegative than bromine and hence has a higher tendency to displace bromine from its compounds. Consequently, bromine remains unreactive in the presence of aqueous potassium chloride.
How does potassium bromide react with other elements?
Potassium bromide can react with elements like chlorine to form potassium chloride and bromine. It can also react with sulfur to form potassium sulfide and bromine. Additionally, it can react with metals like magnesium to form magnesium bromide and potassium.
Can liquid bromine react with potassium iodide?
Yes, liquid bromine can react with potassium iodide to form potassium bromide and elemental iodine. This reaction is a displacement reaction, where the more reactive element (bromine) displaces the less reactive element (iodine).
Do chlorine and potassium bromine react?
Yes, the reaction is:Cl2 + 2 KBr = 2 KCl + Br2
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 would happen if bromine water and potassium astatide were added together?
A reaction would occur between bromine water and potassium astatide, resulting in the displacement of bromine by astatine. This would lead to the formation of potassium bromide and astatine would be released. The solution would likely change color as astatine is a highly reactive halogen with distinctive coloration.
What kind of bond is potassium and bromine?
An ionic bond will form between potassium (K) and bromine (Br). This compound, potassium bromide, KBr, is a salt, which is, in general, the combination of a metal (a Group 1 or Group 2 element) and a halogen (a Group 17 element). All salts are bonded ionically.
Does Bromine react with water?
no
