WebHalo Naufan, saya bantu jawab ya. pH Larutan tersebut adalah 9 + log 2. Garam CH3COONa merupakan garam basa yang terbentuk dari asam lemah CH3COOH dan basa kuat NaOH. Garam ini akan terhidrolisis parsial, dimana ion CH3COO- akan bereaksi dengan air menghasilkan ion OH-. WebNumber of m.moles of CH3– COOH in 250ml of 0.2M solution = (250 x 0.2)= 50 m.moles CH3-COOH + NaOH===> CH3-COONa+ H2O So 1m.mol of NaOH will react with 1m.mole of CH3-COOH to form 1 m.mole of CH3– COONa Therefore in the mixture there will be (50–1)= 49 m.moles of CH3-COOH and 1 m.mole of CH3-COONa. So pH=4.75+log [AcO …
