Assume you had a very magnified view of a solution of HCl that allowed you to "see" the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear and hydrogen gas would be released. Draw this out using symbols to represent the elements, and write out the balanced equation.
HCl in solution is completely ionized, all that exists are ions.
What does this mean in Chemistry it is a type of acid
2HCl(aq)+Mg(s)----->MgCl2(aq)+H2(g)
In an aqueous solution of HCl, there is H+ ions and CL- ions. (Magnified View)
**ignore the OH- ions present in water which hydrochloric acid dissolve into**
When magnesium is dropped inside the hydrochloric acid, the magnesium will react with hydrochloric acid to form aqueous solution of magnesium chlorine and give out hydrogen gas.
Then in the solution, there will be Mg2+ ions and Cl- ions (Magnified View)
**ignore the OH- ions present in water which hydrochloric acid dissolve into**
In a magnified view of a solution of HCl (hydrochloric acid), we would typically represent the HCl molecules as individual ions. The HCl molecule dissociates in water to form hydrogen ions (H+) and chloride ions (Cl-). We can symbolize the hydrogen ions as H+ and the chloride ions as Cl-.
When a piece of magnesium (Mg) is dropped into the HCl solution, a chemical reaction occurs, resulting in the disappearance of magnesium and the release of hydrogen gas (H2).
Here is a representation of the reaction using symbols:
HCl (aq) + Mg (s) → MgCl2 (aq) + H2 (g)
This balanced chemical equation represents the reaction. "aq" refers to an aqueous solution (HCl dissolved in water), "s" refers to solid magnesium, "aq" represents the resulting magnesium chloride dissolved in water, and "g" denotes gaseous hydrogen.
