Now let's see how to make 1 N and 1M H2SO4 from 98% concentrated H2SO4 .
This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84
H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml)
let's use formula
density = mass / volume
volume = mass of HCl / density
98.08 / 1.84
V = 53.30 ml
Here we are making 1M and 1N H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%.
Let's use formula
1M H2SO4 (98%) = 53.30 ml [ V ]
100% = X
X = 53.30 ml × 100% / 98%
X = 54.38 ml
we need to dilute 54.38 ml of 98%. concentrated H2SO4 into 1000 ml Volumetric flask In order to make 1 M H2SO4.
1M H2SO4 = 945.62ML (WATER) + 54.38ML H2SO4 98%.
Let's see how to make 1N H2SO4
. In case of H2SO4 molarity & Normality are different Because-
H2SO4 = H2 + SO4
H2SO4 contain 2 H+ ion means Basicity Of H2SO4 = n = 2
Normality = molarity × n
n = [Basicity of H2SO4 ]
N= M×2
Consider molarity is 1
N= 1 × 2
N = 2
it means if molarity of H2SO4 is 1 then Normality is 2. And molarity is 0.5 then Normality is 1.
If
1M H2SO4 = 945.62ML (WATER) + 54.38ML H2SO4 98%.
Then
1N H2SO4 = 972.81 ML (WATER) + 27.19 ML H2SO4 98%.
To make 1N H2SO4 solutions we need to dilute 27.19 ML 98% concentrated H2SO4 into 1000 ml Volumetric flask.
