Question

If a solution is formed by mixing 0.1 M H2SO4(100ml) and 0.1M HCl(200ml), then molarity of[H+] in resulting solution is???

Answer 1

$\huge\bigstar\underline\orange{Answer}$

given,

Molarity of H2SO4 = 0.1M

and its volume is 100ml

Molarity of HCl= 0.1M

its Volume= 200ml

now, apply formula

N1V1 + N2V2 = N(V1+V2)

here, N= Normality

V1= volume of H2SO4

V2 = volume of HCl

putting the values in formula we get,

(0.1×2) × 100 + 0.1 × 200 = N(100+200)

• Note:- converted molarity into normality by multiplying it with valency factor,

• valency factor for H2SO4 is 2

now,

20 + 20 = N × 300

N = 40/300

N = 4/30

concentration = [H+] = N = 4/30

N= 0.133
