Question

plan an experiment on the effect of sodium chlodride concentration on the volume of oxygen gas produced
​

Answer 1

Answer:

NaCl+O2 ?

there will no reaction takes place because both nacl and oxygen are stavle

Answer 2

Apparatus:

Sodium chloride solution of varying concentrations

Hydrogen peroxide solution (3%)

Measuring cylinder (50 mL)

Test tubes

Rubber stoppers

Delivery tube

Gas syringe

Stopwatch

Distilled water

Procedure:

METHod

Prepare different concentrations of sodium chloride solutions. For example, 0.1M, 0.2M, 0.3M, and so on.

Label the test tubes according to the concentration of sodium chloride solution used.

Add 10 mL of hydrogen peroxide solution into each test tube.

Place the rubber stopper into the test tube.

Insert one end of the delivery tube into the rubber stopper and the other end into the gas syringe.

Fill the measuring cylinder with distilled water and invert it over the open end of the gas syringe to collect the gas.

Wait for 2-3 minutes to allow the reaction to start.

Start the stopwatch and record the volume of gas collected in the measuring cylinder every 30 seconds for a total of 3 minutes.

Repeat the experiment for each concentration of sodium chloride solution.

Calculate the average volume of gas produced for each concentration of sodium chloride solution.

Plot a graph of the concentration of sodium chloride solution against the volume of gas produced.

Repeats: To ensure accuracy, repeat the experiment multiple times and take the average of the results. Also, make sure that the temperature and pressure are constant throughout the experiment.
