Glacial ethanoic acid is pure ethanoic acid CH3COOH. It is called glacial because on cooling it forms glassy crystals. Why must the concentrated sulphuric acid be added slowly and with cooling? The concentrated sulphuric acid on dilution gives out a lot of heat; the slow addition with cooling is necessary to avoid splashing if the mixture gets hot.
