Arey, pehle toh yaad rakhna: pH = pKa + log([salt]/[acid]). Acetate buffer ke liye, maan lo acetic acid hai aur sodium acetate uska salt. Dono ke concentrations daal do, simple calculation ho jaayegi. Mujhe yeh tab samjha jab maine apni bahan ko padhate waqt chart banaya, rang-birange kagaz par likha — jaise dukaan mein patang ke rang alag dikhte hain, waise hi equation alag lagegi. Log kehte hain yeh mushkil hai, par tum dekhna, bas pKa yaad kar lo, phir toh sirf hisaab hai.
