Chem P5 most common planning questions and topics

[borntofly]

Please post the most common chemistry P5 question types you know and you have been asked by your teacher to go through.

the ones i know are:

1. Determining rates
2. Enthalpy changes.
3. Volumetric Analysis

umm.. i don't remember more haha.

Please please everyone post what you know for chem p5

 

[cieko..]

Solubility !!

 

[borntofly]

okay:
let's add it,

1. Determining rates
2. Enthalpy Changes
3. Solubility
4. Volumetric analysis

let's add more, please, it would be great help if we know specifically what we need to focus on.

chromatography
titration

 

[cieko..]

i don think chromatography is asked in Paper 5??

 

[Xam]

anythng can cme for designing.

 

[borntofly]

I scanned through the past papers and these are the types i found:

1. Enthalpy Changes (sometimes using Hess's Law)
2. Determination of Solubility
3. Water of Crystallization (percentage of water lost)
4. Percentage by mass of some elements or compounds in other compounds
5. Elemental Analysis
6. Ion Tests (Qualitative Analysis Notes given)
7. Compostion of given solutions
8. Redox

Please add if you know other types. and if you are interested please post the basics to design each of these types.

Dear friends, please post important notes on planning and analysis that your teacher has given you. thanks.
I desperately need your help for p5.

Why don't you practice p5 past papers ...I think they will really help you alot ... And yeah you can see the relevant experiments from p3 as well

 

[borntofly]

thanks. i will try them.

 

[zahraahmed]

electrophoresis as well!!!

 

[blueindigo]

really?? we need to know all the electropheresis for p5????

 

[zahraahmed]

hey if it can come in paper 5 of biology (bio applications also has the same electrophoresis as chem applications booklet)
so it can also come in chemistry paper 5.
besides he's gave Kpc in paper 5 of chemistry already showing that he CAN give ANYTHING from the applications part as well.

 

[ManishAdhikari]

I shall add one more finding PKa too may be important although not asked yet.

 

[borntofly]

So the list is increasing:
1. Enthalpy Changes (sometimes using Hess's Law)
2. Determination of Solubility
3. Water of Crystallization (percentage of water lost)
4. Percentage by mass of some elements or compounds in other compounds
5. Elemental Analysis
6. Ion Tests (Qualitative Analysis Notes given)
7. Compostion of given solutions
8. Redox (Electrolysis)
9. Electrophoresis
10. Calculating pH, pka, pkb and ksp.

Thanks everyone.

 

[borntofly]

I missed the determining rates one.

1. Enthalpy Changes (sometimes using Hess's Law)
2. Determination of Solubility
3. Determination of rates of reaction
4. Water of Crystallization (percentage of water lost)
5. Percentage by mass of some elements or compounds in other compounds
6. Elemental Analysis
7. Ion Tests (Qualitative Analysis Notes given)
8. Compostion of given solutions
9. Redox (Electrolysis)
10. Electrophoresis
11. Calculating pH, pka, pkb and ksp.

 

[zahraahmed]

hey add some experiment on the organic section as well who knows whether it turns up in paper 5 as well?

 

[Youme&I]

Wow.... tats a lot. paper 5 is a few days ahead and surely need helps in this question! hellpp me guys!!! before its too late!

Hey guys! I m still not sure about paper 5 chemistry, for example a question from Nov10/53 question 1

Using the apparatus shown in (c) design a laboratory experiment to test your prediction
in (a). In addition to the standard apparatus present in a laboratory you are provided with the
following materials.

• 2.00 mol dm–3 aqueous hydrogen peroxide
• a supply of manganese(IV) oxide
(i) Complete the table below to show how you would prepare five solutions of aqueous
hydrogen peroxide. Make sure that the correct units are recorded.
expt No. volume of H2 O2 volume of H2O concentration of H2O2
1
2
3
4
5

Note That: I just dont understand where to get all the amounts to fill in to the table!

can anyone tell me how to explain the anamolies........................

can anyone tell me how to explain the anamolies........................

what anamolies do u exactly mean??
