When chromium(II) iodide is put into water, it undergoes a redox reaction where chromium(II) ions are oxidized to chromium(III) and iodide ions are reduced to iodine. This results in the formation of chromium(III) hydroxide and iodine.
They form Silver Iodide and Poassium nitrate. Silver Iodide is a yellow coloured compound which forms precipitate in the solution. Potassium Nitrate remains dissolved. These reactions only take place in solution. When both reactants are in solid state then reaction may not occur, or it is too slow to be observed.
When chromium bromide is put into water, it dissociates into ions. The reaction is: CrBr2(s) → Cr2+(aq) + 2Br-(aq).
When an alkali and an acid are put together, it is called a neutralization reaction. This reaction results in the formation of water and a salt.
Write the reaction when potassium sulfide is put into water:
This is not a chemical reaction; it is only a dissolution.

Any reaction occur; sucrose is dissolved in water.
Yes, it is true.
When chromium bromide is put into water, it dissociates into ions. The reaction is: CrBr2(s) → Cr2+(aq) + 2Br-(aq).
A water solution is obtained.
This compound is soluble in water.
it reacts with water. it forms OH- by reaction.
When an alkali and an acid are put together, it is called a neutralization reaction. This reaction results in the formation of water and a salt.
Write the reaction when potassium sulfide is put into water:
Any reaction occur.
It produces a bright yellow flame
The salt should be an Iodide salt. Put the iodide salt into concentrated sulfuric acid. This will oxidize iodide to elementary Iodine.I- + H2SO4 ----> I2 + SO2 + H2O + HSO4-Another way is treating iodide salt with Chlorine, which will oxidize iodide to iodine and chlorine will be reduced to chloride.2 I- + Cl2 ----> I2 + 2 Cl-
