Magnesium ribbon reacts with dilute hydrochloric acid to produce hydrogen gas.
magnesium+hydrochloric acid→magnesium chloride+hydrogen \text{magnesium} + \text{hydrochloric acid} \rightarrow \text{magnesium chloride} + \text{hydrogen} magnesium+hydrochloric acid→magnesium chloride+hydrogenA student investigated the effect of doubling the concentration of the hydrochloric acid on this reaction.
The student made the following prediction:
"When the concentration of the hydrochloric acid is doubled, the initial rate of reaction will double and the overall reaction will show a greater increase in temperature."
Devise a plan, including the apparatus you would use, to test this student's complete prediction.
You are provided with strips of magnesium ribbon, a thermometer, and two bottles of dilute hydrochloric acid. One bottle of hydrochloric acid is exactly double the concentration of the other.
