sir ferrous sulphate or iron sulphate me kya antar hai
sagar iron d' block ka element hai jis karan se do tarah ke valancy so karta hai(lesser valancy wale ko ferrous aur greater valancy wale ko feric kaha jata hai jab yah kisi compound or molecule ka formation karta hai) agar sirf iron sulphate diya hua hai iska matlab ye ya to ferrous sulphate hoga or ferric sulphate) I hope ur all doubt will be clear if not then feel free to ask.
