What happens to the conductivity of water when an acid is dissolved in it?
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.
How FeCl2 is made?
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.
What happens when FeCl3 is dissolved in water?
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.
What happens to the boiling point of water if something is dissolved in it?
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.
What happens when lye is dissolved in water?
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.
