Yes, the research question is clear and grammatically correct. However, there are a few suggestions for improvement:
1. Clarify the concentration values:
- Specify the initial concentration of sulfuric acid (e.g., 0.1 M).
- Indicate the concentrations used when diluting the acid (e.g., 0.05 M, 0.025 M, etc.).
2. Emphasize the independent variable:
- Instead of "changing concentration through diluting sulfuric acid," consider saying "how varying the concentration of sulfuric acid through dilution affects..."
3. Specify the unit used for volume of hydrogen gas:
- For example, "as measured by the volume of hydrogen gas (in milliliters) produced?"
Revised research question example:
"What is the correlation between varying the concentration of sulfuric acid (H2SO4) through dilution (initial concentration: 0.1 M) and the rate of reaction with magnesium (Mg, 0.05 g), as determined by the volume of hydrogen gas (measured in milliliters) produced?"
