which acid solution will react the fastest with a 1 cm piece of mg ribbon?
which acid solution will react the fastest with a 1 cm piece of mg ribbon?
Answer
Explanation:
Step1: Recall reaction - rate principle
The rate of a reaction between an acid and magnesium is proportional to the concentration of the acid (assuming all other factors like temperature, surface - area of Mg are constant). Higher acid concentration means more hydrogen ions available to react with magnesium.
Step2: Compare given concentrations
We have three acid concentrations: 2.0 M, 0.1 M, and 1.0 M. Among these, 2.0 M is the highest concentration.
Answer:
The 2.0 M acid solution will react the fastest with the 1 cm piece of Mg ribbon.
