Answer :
To determine which acid solution will react the fastest with a 1 cm piece of magnesium (Mg) ribbon, we need to understand the factors that affect the rate of a chemical reaction. One of the key factors is the concentration of the reactants. In this case, the concentration of the acid solution will play a crucial role in the reaction rate.
The reaction between magnesium and an acid typically produces hydrogen gas and a magnesium salt. The general reaction can be represented as:
[tex]\[ \text{Mg (s)} + 2\text{H}^+ (\text{aq}) \rightarrow \text{Mg}^{2+} (\text{aq}) + \text{H}_2 (\text{g}) \][/tex]
When the concentration of the acid is higher, there are more hydrogen ions ([tex]\(\text{H}^+\)[/tex]) available to react with the magnesium. This increased concentration of reactants leads to an increased frequency of collisions between reactant particles, thereby accelerating the reaction rate.
Given the options:
- 0.1 M acid solution
- 1.0 M acid solution
- 2.0 M acid solution
The 2.0 M acid solution has the highest concentration of hydrogen ions compared to 1.0 M and 0.1 M acid solutions. Therefore, the 2.0 M acid solution will provide more hydrogen ions to react with the magnesium ribbon, resulting in the fastest reaction rate.
In conclusion, the 2.0 M acid solution will react the fastest with a 1 cm piece of magnesium ribbon.
