MODULE 8 UNIT 2 Assignment Part C 1.
Calculate the volume of lithium hydroxide at 0.12 M. required to neutralize 25 mL of sulphuric acid at 2.5 M. 3 marks 2. A sample of 2.5 g of solid NaOH will neutralize 125 mL of sulphuric acid. Calculate the molarity of the sulphuric acid. 3 marks 3. Lactic acid, HC3H5O3, is the acid, which forms when milk sours. As its formula indicates, this acid has an acid hydrogen ion.
It requires 22.4 mL of NaOH at 0.156 M to neutralize the acid in a sample of 25.0 mL of lactic acid. Calculate the mass of lactic acid contained in the sample. 3 marks 4. Vinegar is a dilute solution of acetic acid. What is the concentration of acetic acid in the vinegar if 26.5 mL of NaOH at 0.250 M are required to
