(a) Complete the instructions for Step 1. 1 (b) The equation for the reaction is: H2SO4 + 2NaOH Na2SO4 + 2H2O In the experiment 50cm3 of sodium hydroxide solution reacted with 20cm3 0·1 mol l–1 dilute sulphuric acid. Calculate the concentration, in mol l-1, of the sodium hydroxide solution. 2 2007 C 20 10. Indigestion is caused by excess acid in the stomach. Indigestion remedies containing calcium carbonate neutralise some of this acid.
