Calculate the molarities and normalities of the solutions obtained on

1.	Calculate the molarities and normalities of the solutions obtained on mixing.(i) 100 mL of 0.2 M H2SO4 with 50 mL of 0.1 M HCl.
Answer» Your newborn may be VULNERABLE to these 6 serious diseases. Normality of any acid or BASE will be equal to gram-equivalent desolve in given volume N = gram-equivalent/ volume(lt.) When TWO or more compounds or elements react together their gram-equivalent will be equal in simple way, 10 gm-eq of an acid will react completely with 10 gm-eq of base, In given problem, gm-eq. of H2SO4 = NV(lt.) and N = nM where, M = molarity and n = basicity or acidity of an acid or base. gm-eq of H2SO4 = 10020.20.001 =0.04gm-eq gm-eq of NaOH = 1000.210.001 =0.02 remaining gm-eq of H2SO4 = 0.04–0.02 0.02gm-eq Now, gm-eq. = NV = 0.02 Total volume =200ml = 0.2 lt. N0.2 = 0.02 = 0.1N Hope you find it HELPFUL!!!

Calculate the molarities and normalities of the solutions obtained on mixing.(i) 100 mL of 0.2 M H2SO4 with 50 mL of 0.1 M HCl.

Answer»

Your newborn may be VULNERABLE to these 6 serious diseases.

Normality of any acid or BASE will be equal to gram-equivalent desolve in given volume

N = gram-equivalent/ volume(lt.)

When TWO or more compounds or elements react together their

gram-equivalent will be equal in simple way, 10 gm-eq of an acid will react completely with 10 gm-eq of base,

In given problem,

gm-eq. of H2SO4 = N*V(lt.)

and N = n*M where, M = molarity and n = basicity or acidity of an acid or base.

gm-eq of H2SO4 = 100*2*0.2*0.001

=0.04gm-eq

gm-eq of NaOH = 100*0.2*1*0.001

=0.02

remaining gm-eq of H2SO4 = 0.04–0.02

0.02gm-eq

Now,

gm-eq. = N*V = 0.02

Total volume =200ml = 0.2 lt.

N*0.2 = 0.02 = 0.1N

Hope you find it HELPFUL!!!
