Question
#Practical: Add small pieces of magnesium and calcium to some dilute hydrochloric in separate test tubes. Observe the reaction, especially noting the rate at which hydrogen is evolved in each.Question, which metal seems to react faster?

In a reaction with dilute hydrochloric acid (HCl), calcium generally reacts faster than magnesium.
When small pieces of calcium are added to dilute hydrochloric acid, you will observe vigorous bubbling and a rapid evolution of hydrogen gas. This is due to calcium being a more reactive metal compared to magnesium.
In contrast, magnesium does react with hydrochloric acid, but the reaction is typically slower, especially at room temperature. You would observe less vigorous bubbling and a slower evolution of hydrogen gas compared to the reaction with calcium.
In summary, calcium seems to react faster than magnesium when added to dilute hydrochloric acid.
