TGS Collision Theory Magnesium and Hydrochloric Acid JBI

A student investigates the reaction between magnesium and hydrochloric acid.

Write a word equation for this reaction.

What ions does hydrochloric acid release?

The student investigated how changing the concentration of the hydrochloric acid affects this reaction. Each test tube below contained a different concentration of hydrochloric acid. The diagrams show the results of this experiment.

Which test tube had the most concentrated acid?

The student investigated how changing the concentration of the hydrochloric acid affects this reaction. Each test tube below contained a different concentration of hydrochloric acid. The diagrams show the results of this experiment.

Why did you chose your answer to Q3 as the test tube with the most concentrated acid?

The student investigated how changing the concentration of the hydrochloric acid affects this reaction. Each test tube below contained a different concentration of hydrochloric acid. The diagrams show the results of this experiment.

Which test tube had the least concentrated acid?

The student investigated how changing the concentration of the hydrochloric acid affects this reaction. Each test tube below contained a different concentration of hydrochloric acid. The diagrams show the results of this experiment.

Once the reaction in each test tube had finished, which will have produced the most gas?

Suggest one control variable for this experiment

State the effect of increasing the concentration on the rate of reaction and why
