Reacted 1g of charcoal with water 20ml and 0.5M of CH3COOH 30ml and allow to equilibrate. And for the stock solution 5ml of 0.5M CH3COOH was titrated against 0.1M NaOH to get a stock concentration of 0.5M. Upon equilibrium, 10ml CH3COOH aliqout was titrated againt 0.1M NaOH. How do can I obtain the moles added, moles used and the mole adsorbed by the charcoal. Please can any one help
