A3. answer each of the following: a student dissolved 1.3g of ba(oh)2 (molar mass = 171.34 g/mol) in 250 ml of water and reacted it with 0.125 m hno3 until the solution was neutral. (i) write a balanced chemical equation to describe the reaction. [4 marks] (ii) how many ml of hno3 are required to react completely with the ba(oh)2 solution? [7 marks] (iii) calculate the molarity of the ba(oh)2 solution. [3 marks] (iv) suggest a suitable indicator for the reaction. [3 marks] (v) if instead 150 ml of 0.125 m hno3 was reacted with the ba(oh)2 solution, calculate the ph of the solution. [8 marks]
