Measuring the Molar Volume of a Gas

What safety precautions should be taken?

Draw a Diagram of the required equipment:

Describe the Procedure

What does the graph look like? Label the axes

What's the equation for ethanoic acid and calcium carbonate

Why is it more accurate to find the CaCO3 by weighing the test tube with it in then tipping it out and reweighing the test tube than to weigh the empty test tube at the start.

Identify the major source of error caused by the procedure used.

What change to the procedure or apparatus could be made to eradicate this error?

Find the concentration of a solution of NaOH

Safety Precautions

Procedure:

Why should the pipette be rinsed with the NaOH solution after washing it with water?

Why is there no need to dry the conical flask after washing it out between trials?

Find the concentration of solution of HCl

Safety:

Procedure:

Hydrolysis of Halogenoalkanes

Safety:

Procedure #1:

Procedure #2:

Reactivity:

CH3CH2CH2CH2Br+ H20 --->

Hwy is water used as the nucleophile rather than OH- ions?

Why is ethanol used in this reaction

Investigate the oxidation of ethanol

Safety:

Draw the Diagram:

Procedure:

Distillation apparatus

Test performed on the distillate:
1- pH
2- Add a few drops of acidified sodium dichromate solution to 1cm3 of the distillate and warm in a 60C water bath
3- Add a quarter of a spatula of CaCO3 to 1mc3 of the distillate.
4- Add magnesium strip
5- Add Fehling's solution and warm.

CH3CH2OH+2[O] ---[H+]-->

2CH3COOH+Mg --->
2CH3COOH+ CaCO3 --->

Investigate the chlorination of 2-methylpropan-2-ol

Safety:

Procedure:

Procedure continues....

How would you test for the product that's made?

CH3CH2(CH3)(OH)CH3+ HCl --->

What is removed from the crude product when it is shaken with NaHCO3?

Identify unknown organic liquids and inorganic solids

Safety:

Procedure #1:

Procedure #2:

Calculate the enthalpy change for the thermal decomposition of KHCO3

Safety:

Procedure:

K2CO3 + 2HCl -->

KHCO3 + HCl -->

How would use the results to calculate the enthalpy change of decomposition of potassium hydrogencarbonate?

Why is it not possible to measure the enthalpy change of decomposition directly?

Explain why reactions are conducted in a polystyrene cup rather than a glass beaker
