Titration (Oxalic Acid)

(a) To prepare 100ml of M/40 solution of oxalic acid.                                                

(b)Using this calculate the molarity and strength of the given KMnO 4  solution.  

APPARATUS AND CHEMICALS REQUIRED –

Oxalic acid, weighing bottle, weight box, volumetric flask, funnel, distilled water, chemical balance, beakers, conical flask, funnel, burette, pipette, clamp stand, tile, dilute H 2 SO 4 , KMnO 4  solution.

(a) THEORY –

Oxalic acid is a dicarboxylic acid having molar mass 126gmol -1 . It is a primary standard and has the molecular formula COOH-COOH.2H 2 O. Its equivalent mass is 126/2 = 63 as its  n  factor is 2 as per the following reaction:

COOH-COOH → 2CO 2  + 2H +  + 2e – .

• Weigh a clean dry bottle using a chemical balance.
• Add 3.15g more weights to the pan containing the weights for the weighing bottle.
• Add oxalic acid in small amounts to the weighing bottle, so that the pans are balanced.
• Remove the weighing bottle from the pan.
• Using a funnel, transfer the oxalic acid to the volumetric flask.
• Add a few drops of distilled water to dissolve the oxalic acid.
• Make up the volume to the required level using distilled water .
• The standard solution is prepared.

(b)  T HEORY –

• The reaction between KMnO 4  and oxalic acid is a redox reaction   and the titration is therefore called a redox titration.
• Oxalic acid is the reducing agent and KMnO 4  is the oxidizing agent.
• KMnO 4  acts as an oxidizing agent in all the mediums; i.e. acidic, basic and neutral medium.
• KMnO 4  acts as the strongest oxidizing agent in the acidic medium and therefore dil. H 2 SO 4  is added to the conical flask before starting the titration.
• The titration between oxalic acid and KMnO 4  is a slow reaction, therefore heat the oxalic acid solution to about 60 0 C to increase the rate of the reaction.

  IONIC EQUATIONS INVOLVED:  

Reduction Half:    MnO 4 –  + 8H +  + 5e –   →  Mn 2+  + 4H 2 O] X 2

Oxidation Half:     C 2 O 4 2-   →  2CO 2   + 2e –  ] X 5

Overall Equation:   2MnO 4 –  + 16H +  + 5C 2 O 4 2-  → 2Mn 2+  + 10CO 2  + H 2 O

  INDICATOR – KMnO 4  acts as a self indicator.

  END POINT – Colourless to light pink (KMnO 4  in the burette)

  PROCEDURE –

1. Fill the burette with KMnO 4  solution.

2. Pipette out 10ml. of oxalic acid solution into the conical flask.

3. Add half a test tube of dil. H 2 SO 4  and heat the solution to about 60 0 C to increase the rate of the reaction.

4. Keep a glazed tile under the burette and place the conical flask on it.

5. Note down the initial reading of the burette.

6. Run down the KMnO 4  solution into the conical flask dropwise with shaking.

7. Stop the titration when a permanent pink colour is obtained in the solution.

8. This is the endpoint. Note down the final burette reading.

9. Repeat the experiment until three concordant values are obtained.

  OBSERVATION TABLE:  (TO BE PUT UP ON THE BLANK SIDE USING A PENCIL)

Volume of Oxalic Acid solution taken = 10mL

Concordant Value = 10.5mL

  CALCULATIONS:  (TO BE PUT UP ON THE BLANK SIDE USING A PENCIL)

Calculation of amount of oxalic acid to be weighed to prepare 100ml M/20 solution:

  Molecular Mass of Oxalic Acid = 126g/mole

1000 cm 3  of 1M oxalic acid require 126g oxalic acid.

1000 cm 3  of M/40 oxalic acid require =126/40g = 3.15g

Using formula:

N 1 M 1 V 1  = N 2 M 2 V 2

Where N 1 = 5   (for KMnO 4 ), V 1 =   10.5            , M 1  = ?

N 2 = 2   (for oxalic acid), V 2  =   10ml, M 2  = 1/40

M 1  = [2*(1/40)*10]/[5*10.5] = 1/105M = 0.0095M

S trength = M X Molar Mass = 158 *( 1/105) = 1.504g/L

  RESULT-  (ON RULED SIDE ) –

The Molarity of KMnO 4  =   0.0095M

And the strength of KMnO 4  =     1.504g/L

Thanks for guidance

Helpful , to a large extent

Thanks for guidance and good theory

Thanq for giving information regarding practicals

Calculation is 100% right….. Bcz in our school sir has told from other formula….. M1V1/N1 =M2V2/N2….plz tell which one is right….

In ur formula N1 and N2 are stoicio.. Coeff of kmno4 and (cooh)2 in balanced formula respectively

formula for the calculation of normaility—- no.of gram equivalent = normality x volume no. of gram equivalent = molarity x volume x n-factor correct formula is- M1 X V1 X N1 = M2 X V2 X N2

Gorgeous one guys 🤗

Gorgeous one guy 🤗

Really it is very nice 🐞🐞🐞

Thanks a lot for this free notes…

Thanks for help

is this observations are right…??

How to prepare M/10 kmno4

Oxalic acid ka weight 0.315 g hoga n ki 3.15g

much helpful to me really thank you …..

I think the weight of oxalic acid should be 0.315g not 3.15g because we have to make 100ml solution not 1000ml solution.

Really helpful 👍, thanku

Very helpful👍

Mazza aaya👌

Very Helpful. Thanks!!

Thank you from the bottom of my heart.😘😘😘😘😘

Thankyou so much for this pratical
