Write the reaction when potassium sulfide is put into water:
This is not a chemical reaction; it is only a dissolution.
A reaction takes place and a gas is released.
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 10g of sodium are put into 100g of water, the reaction produces only 109.6g of sodium hydroxide because of the sodium's solvency. Some of the sodium is displaced in the reaction, and this is why it does not seem to add up.
Write the reaction when potassium sulfide is put into water:
Yes, it is true.
Any reaction occur; sucrose is dissolved in water.
This is not a chemical reaction; it is only a dissolution.
A water solution is obtained.
This compound is soluble in water.
it reacts with water. it forms OH- by reaction.
Co2+ + 2SO4
Any reaction occur.
A reaction takes place and a gas is released.
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-
It produces a bright yellow flame
