Chemical Reactions and Measurements

The video tutorial demonstrates a chemical experiment involving the mixing of ethanol and concentrated sulfuric acid in a test tube. The mixture is sealed with a gas outlet tube and heated. The resulting gas is tested for reactions with potassium permanganate and bromine water, with observations noted for each interaction.

How much ethanol is added to the test tube?

• 4 milliliters

• 1 milliliter

• 2 milliliters

• 3 milliliters

What is the volume of concentrated sulfuric acid added to the test tube?

• 4 milliliters

• 2 milliliters

• 3 milliliters

• 1 milliliter

What is used to close the test tube after adding the chemicals?

• A rubber stopper

• A gas outlet tube

• A cork

• A glass lid

Which chemical is used to observe the interaction with the gas first?

• Bromine water

• Potassium permanganate

• Ethanol

• Sulfuric acid

What is the second solution used to observe the gas reaction?

• Bromine water

• Ethanol

• Sulfuric acid

• Potassium permanganate
