The Effect of Different Concentrations on the Rate of Reaction between Magnesium Ribbon and Hydrochloric Acid:

Research Question:

Does doubling the concentration of hydrochloric acid; double the rate of reactions when magnesium ribbon reacts with hydrochloric acid?

Hypothesis:

I believe that if we double the amount of hydrochloric acid concentration, the rate of reaction will also double. This maybe the case, because there is double the amount of particles reacting, hence, double the amount of collisions per second, causing double the amount of successful collision per second due to double the amount of kinetic energy. Hence, the reaction would finish in half the time.

Independent Variable

Dependent Variable

Controlled Variable

Concentration of hydrochloric acid- greater the amount of concentration, faster the rate of reaction.

Volume of carbon dioxide gas produced in a certain amount of time- there must be a correlation between the acid concentration and the rate of reaction.

Temperature- the temperature can affect the rate of reaction. Hence, must be kept at constant by thermostat to have accurate result.

Length of Magnesium Ribbon- must be kept at constant as longer the length the faster
