student found that 37.6 cm' of 0.500 mol/dm sulfuric acid was needed to neutralise 25.0 cm' of potassium hydroxide solution. How many moles of sulfuric acid were needed to neutralise the potassium hydroxide? (2 marks) The equation for this reaction is H,SO, 2KOH → K,SO, 2H20 Calculate the concentration of the potassium hydroxide solution in this experiment.
