WAEC Chemistry Practical Answers

Burette readings;
|Rough |1st |2nd|3rd|

Final readings in cm³;
|22.00|20.10 |20.20|20.30|

Initial reading in cm³;
|0.00|0.00|0.00 |0.00|

Volume of A (acid) used cm³;
|22.00|20.10|20.20| 20.30|

The average titre
= 20.10+20.20+20.30/3
= 20.20cm³

;Va 20.20cm³

Concentration of A in mol/dm³, Ca = ?

Concentration of A (g/dm³) = 4.40g/dm³.

.m.m of A, H²SO⁴ =(1*2)+(32*1)+(16*4)

Using concentration (mol/dm³) = Concentration (g/dm³)/m.m

Concentration (mol/dm³)

;: Concentration of A(mol/dm³) = 0.045mol/dm³

Concentration of B(mol/dm³) =???
Ca=0.045, Va=20.20, Vb=25.00, na=1, nb=1, cb=?

Using; CaVa/CbVb = na/nb
Cb=CaVanb/Vbna =0.045*20.20*1/25.00*1

Conc. of B(g/dm³) that reacted =??
molar mass of B, Na₂CO₃ = (23*2)+(12*1)+(16*3) = 106g/mol

Conc. of B(mol/dm³) = 0.036mol/dm3
Conc. (mol/dm³) = Conc. (g/dm³)/molar mass

(0.036/1) = Conc. (g/dm³)/106

Conc. (g/dm³) = 0.036*106 = 3.82g/dm³
Conc. of B(g/dm³) = 3.82/dm³

mass of the impurity in 1.0dm³ of B=??
Conc. of impurity (g/dm³) = 7.50 – 3.82 = 3.68g/dm³

:. Mass of impurity= Conc. (g/dm³) x vol. (dm³)
= 3.68×1 = 3.68g

Vol. of CO₂ produced in 1.0dm³ of B = ??

Mole of B= Conc. x Vol. (dm³)
Mole of B = 0.036*1
Mole of B =0.036mol

By proportion,
1mol of Na₂.10₃ = 1mol of CO₂

0.036mol of Na₂.10₃ = xmol of CO₂

mole of CO₂ produced = 1*0.036 = 0.036mol

:. Volume = mole * 22.4 = 0.81dm³
