(1) Solute per mol/dm3 1 of 11 Concentrated solutions contain more what in the same what? (2) More solute in the same volume of solution 2 of 11 What is added to dilute a solution? (1) Water 3 of 11 Give an example of a strong acid (1) Hydrochloric acid 4 of 11 Give an example of a weak acid? (1) Citric acid 5 of 11 Strong acids do what in solution and this reaction is what? (2) Ionise completely; non-reversible 6 of 11 Weak acids do what in solution and this reaction is what? (2) Ionise partially; reversible 7 of 11 A stronger acid therefore has what? (1) Higher concentration of H+ ions 8 of 11 As H+ ion concentration decreases by a factor of 10, what happens to pH? (1) Increases by 1 unit 9 of 11 0.1 H+ per mol/dm3 equals what pH? (1) 1 10 of 11 0.01 H+ per mol/dm3 equals what pH? (1) 2 11 of 11
