🧪💡 How to calculate Normality of a solution?
To find the Normality (N) of a solution, use this simple formula:
N=Given mass/Equivalent weight×Volume (L)
N=Equivalent weight×Volume (L)Weight of solute (g)
🧠 Example:
👉 What is the normality of a solution that contains 19.6 g of H₂SO₄ in 20 mL of solution?
✨ Step-by-step:
Molar mass of H₂SO₄ = 98 g/mol
Basicity (number of H⁺ ions) = 2
Equivalent weight = 98 ÷ 2 = 49 g/equiv
Volume in L = 20 mL = 0.020 L
Now plug into the formula:
N=19.649×0.020=19.60.98=20 N
N=49×0.02019.6=0.9819.6=20N
📌 Final Answer:
✅ The normality is 20 N

What’s the difference between Inversion and Reciprocal Translocation?
Let’s make it simple!
🔄 Inversion
A piece of one chromosome breaks off, flips around, and sticks back on in the opposite direction!
No extra or missing DNA — just reversed.
Happens inside the same chromosome.
Can be harmless, but may cause problems during reproduction.
Two types:
Paracentric (centromere NOT involved)
Pericentric (centromere IS involved)
🔁 Reciprocal Translocation
Two different chromosomes break and swap pieces with each other!
Usually no DNA lost — just moved around (called "balanced").
If some DNA is lost or duplicated, it’s called "unbalanced" — and that can cause problems.
Might not affect the person, but can cause miscarriages or genetic conditions in children.
⚡ Quick Summary:
Inversion = Flip within ONE chromosome.
Reciprocal Translocation = Swap between TWO chromosomes.
