When FeCl2 is dissolved in water, it dissociates into Fe2 ions and Cl- ions. This forms a solution that conducts electricity and has a yellow-green color.
When an acid is dissolved in water, it increases the conductivity of water. This is because acids dissociate into ions in water, increasing the presence of charged particles that can conduct electricity.
Iron(II) chloride (FeCl2) can be made by reacting iron with hydrochloric acid (HCl). The reaction produces FeCl2 and hydrogen gas (H2). Another method involves the reaction of iron oxide (FeO) with hydrochloric acid to form FeCl2 and water (H2O). FeCl2 can also be obtained by reducing iron(III) chloride (FeCl3) with hydrogen gas (H2) or with another reducing agent.
When FeCl3 is dissolved in water, it dissociates into Fe3 ions and Cl- ions. This forms a solution that is yellow-brown in color due to the presence of the Fe3 ions.
The boiling point of water increases when a solute is dissolved in it. This is because the presence of a solute disrupts the hydrogen bonding between water molecules, making it harder for them to break free and vaporize.
When lye is dissolved in water, it undergoes a chemical reaction that produces heat and forms a caustic solution called sodium hydroxide. This solution is highly alkaline and can cause burns or irritation if it comes into contact with skin or eyes.
Copper is dissolved:2 FeCl3 + Cu = 2 FeCl2 + CuCl2
Ferric Chloride forms hexa-aquacomplexes in water (water hydrates it). So yes it is soluble.
When water evaporates, salts dissolved in the water are left behind and form solid crystals.
Salt is dissolved in water and pepper not.
They are partially dissolved.
Amphetamine has a very low solubility in water.
Perchloric acid is dissociated in water.
nothing happens.
It easily dissolves and is disassociated.
Ionic salts are dissociated in ions.
They have to be soluble in water - dissolved
This object become warmer, or react with water, or is dissolved.
