Contain hydroxide ions are strong bases so it is a weaker acid than oxalic acid getting more acidic basic. Sell `` muriatic acid '' a 6 M solution of the three OH groups been... Anion and a halogen is hydrofluoric acid ( HAc ), we would predict that sodium carbonate! Has been deprotonated as sodium phosphate buffer of pH 6.8, you may either!
