A solution made from pure barium hydroxide contained 2.74g in exactly 100cm3 of water. Using phenolphthalein indicator, titration of 20.0cm3 of this solution required 18.7cm3 of a hydrochloric acid solution for complete neutralisation.(Atomic masses: Ba =137, O=16,H=1). (a) Write the equation for the titration reaction. (b) Calculate the concentration of the barium hydroxide solution. (c) Calculate the moles of barium hydroxide neutralised.(d) Calculate the moles of hydrochloric acid neutralised. (e) Calculate the concentration of the hydrochloric acid.
