VOLUMENTRIC ANALYSIS QUESTION

1. 'A' is a solution of tetraoxosulphate(vi) B is a solution containing of potassium hydroxide per 25.0cm3.
(a.) Put A into burette and titrate with 20.0cm3 or 25.0cm3 portion into of B using Methyl Orange as
an indicator. Record the volume of your pipette. Tabulate your burette readings and calculate the average volume of acid used.

(b.) From your result and information provided. Calculate the following
(i.) Concentration of B in mol/dm3
(ii.) Concentration of A in mol/dm3
(iii.) Number of Hydrogen ions in 1.0dm^2 of A.

The equation for the reaction is: H2SO4 + 2KOH -->k2SO4 + 2H2O. {H=1, O=16, K=39}
SOLUTION
Burrete reading(cm3)| Rough | 1st | 2nd | 3rd Final(cm3) | 18.60| 18.00| 20.30| 28.00
Initial(cm3) | 0.00 | 0.00 | 2.30 | 10.00
Vol. Acid used(cm3)| 18.60| 18.00 | 18.00| 18.00
The average volume of acid used = 18.00 + 18.00 + 18.00/3 = 18.00cm3.

(bi.) Mass of KOH per dm3 of B = 39+16+1= 56. Conc. of B = 5.6/56= 0.01mol/dm3.
(bii.) The equation for the reaction is: H2SO4 + 2KOH --> k2SO4 + 2H2O. From the equation ==> Conc of A
* Volume of A
* Mole ratio = CA*18.00/0.10*2 = 1/2
Therefore, CA= 0.10
* 25/2*18'
CA= 0.0694mol/dm3.

(biii.) 1dm3 of 1.0mol/dm3
H2SO4 contains (2*6.0*10^23).
Hydrogen atom ==> 1dm3 of 0.694mol/dm3
H2SO4 contains 2*6.0*10^23 = 8.328x10^22.

(2ai).(iii.) To the second portion of the resulting solution
(2ai), add few drops of BaCl2(aq) followed by excess dil HCl.
(bi.) To about 2cm3 portion of the resulting solution in a test-tube, add NaOH in drops and in excess. (ii.) To another portion of the resulting solution, add few drops of dilute trioxonitrate.
