A chemist is studying a reaction involving the reaction of magnesium and hydrochloric acid to produce hydrogen gas a magnesium chloride. The method that she will likely use to measure the rate of reaction is
a) measuring the volume of gas used up
b) measuring the volume of gas produced
c) measuring the volume of liquid used up
d) measuring the volume of magnesium chloride produced
e) measuring the volume of magnesium produced
b) measuring the volume of gas produced
are you sure?
Yes, I am sure. When magnesium reacts with hydrochloric acid, one of the products is hydrogen gas. Therefore, by measuring the volume of gas produced, the chemist can determine the rate at which the reaction is occurring.
The chemist is likely to measure the rate of reaction by measuring the volume of gas produced. Gas production is a common method for determining the reaction rate in many chemical reactions, as it provides a clear indication of the progress of the reaction.
To measure the volume of gas produced, the chemist can set up the reaction in a sealed container with a gas collection apparatus, such as a gas syringe or a gas burette. As the reaction proceeds, hydrogen gas is produced, and its volume can be measured directly using the gas collection apparatus. The rate of reaction can then be calculated by determining the change in volume of gas over a specific time period.
Therefore, the correct answer is option b) measuring the volume of gas produced.
