Here's a breakdown of what happens:
* The reaction: Zinc is more reactive than hydrogen, so it displaces hydrogen from hydrochloric acid. This is a single displacement reaction.
* The equation:
```
Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)
```
* Explanation:
* Zn(s): Solid zinc metal.
* 2HCl(aq): Aqueous hydrochloric acid (dissolved in water).
* ZnCl₂(aq): Aqueous zinc chloride (dissolved in water).
* H₂(g): Hydrogen gas, which is released as bubbles.
Observations:
* You'll see bubbles of hydrogen gas forming and escaping from the solution.
* The solution will heat up as the reaction is exothermic.
* The zinc metal will dissolve as it reacts with the acid.
* The solution will change color from clear to pale yellow as zinc chloride forms.
Safety Precautions:
* This reaction produces flammable hydrogen gas. Avoid flames or sparks near the reaction.
* Hydrochloric acid is corrosive. Wear appropriate safety gear, including gloves and eye protection.
* Work in a well-ventilated area.
