How can I investigate whether iron(II) sulphate tablets get significantly oxidised depending on whether the tablets are crushed or whole?
• I am doing my A2 practical investigation for OCR Salters on the amount of iron in iron tablets. I have decided to use three different methods and compare different brands of iron tablets. I have already identified 2 methods – titration and colorimetry. However, I cannot think of the third and last one. Also what are the three best brands of iron tablets to use and compare as I have heard that not all iron tablets work in the titration experiment? • How do you find the percentage of MgCO3 in an indigestion tablet using a) thermal decomposition b) reaction with an acid Plus could you include relative equations and safety precautions to help me with my question. • Hi. I am doing my advanced higher chemistry project on finding the best procedure to do a weak acid/weak alkali titration. Could you please tell me how I would know if my results were correct. The solutions I am using are: Calcium hydroxide Barium hydroxide Ammonia Citric acid Ethanoic acid and finally Oxalic acid. • Hi, I am
