####53. A 5 molar solution of H2SO4 is diluted from 1 litre to a volume of 10 litres, the normality of the solution will be :

[1991]

(a) 1N

(b) 0.1N

(c) 5N

(d) 0.5N

Show Answer

Solution:

54 .

(a) 5MH2SO4=10NH2SO4, (. Basicity of H2SO4=2 )

N1V1=N2V2, 10×1=N2×10 or N2=1N

(a) Mg2++Na2CO3MgCO3+2Na+

1g eq. 1g eq.

1g eq. of Mg2+=12g of Mg2+=12000mg

=1000 milli eq. of Na2CO3

12mgMg2+=1 milli eq. Na2CO3
