Question

Sulphuric acid is used in the manufacture of this fertiliser and some has leakedonto fittings made of a magnesium alloy. This reaction produces hydrogen gasMg(s) + H₂SO₄(aq)----- MgSO₄(aq) + H₂(g)

Design a method to measure the rate of this reaction, and list the measurements.

(a) Measure the initial mass of magnesium (g).
(b) Record the volume of hydrogen gas produced over time (mL).
(c) Monitor the temperature of the reaction mixture (°C).
(d) Track the pH of the solution over time.

Answer 1

To measure the rate of the reaction between magnesium alloy and sulphuric acid, you can measure the initial mass of magnesium, record the volume of hydrogen gas produced over time, monitor the temperature of the reaction mixture, and track the pH of the solution over time.

Step-by-step explanation:

To measure the rate of the reaction between magnesium alloy and sulphuric acid, you can:

1. Measure the initial mass of magnesium in grams.
2. Record the volume of hydrogen gas produced over time in milliliters.
3. Monitor the temperature of the reaction mixture in degrees Celsius.
4. Track the pH of the solution over time.
