Bhai, pehle group ka reagent HCL hota hai, fir H2S wala! Correct order yaad rakh, warna meri tarah Pb+2 ko Cu+2 samajh baithoge! 🤦♂️ Mujhe practical mein fail hone ka dukh isliye hua kyunki maine order mix-up kar diya tha... aaj bhi yaad hai jab meri solution galat colour de rahi thi! Isliye sun, sirf reagents ratt mat, unka sequence bhi yaad rakh! 💪
