Question

A student investigates how the concentration of an acid affects the speed of a reaction with a 0.5 g mass of magnesium at 30°C. Which pieces of apparatus does the student use?

A. P, Q, and R Only
B. P, Q, and S Only
C. Q, R, and S Only
D. P, Q, R, and S

Answer 1

To study the effect of acid concentration on reaction rate, a student would typically use beakers or flasks, a balance, a thermometer, a timer or stopwatch, and pipettes or burettes.

Step-by-step explanation:

To investigate how the concentration of an acid affects the speed of a reaction, a student would need various pieces of apparatus including, but not limited to, the following:

• Beakers or flasks for containing the reaction mixture
• A balance to measure the mass of magnesium
• A thermometer to ensure the solution is at the correct temperature (30°C)
• A timer or stopwatch to measure the rate of the reaction
• Pipettes or burettes to accurately measure the concentrations of acid

This equipment would facilitate precise measurement and control of the variables in question, providing the necessary data to determine the effect of acid concentration on reaction speed.
