  "text": "According to the sample's carbonate content, weigh a portion of the sample as shown below:\n0,5 g for products containing from 50 % to 100 % of carbonates, expressed as calcium carbonate,\n1 g for products containing from 40 % to 50 % of carbonates, expressed as calcium carbonate,\n2 to 3 g for other products.\nPlace the portion of the sample in the special flask (4) of the apparatus, fitted with a small tube of unbreakable material containing 10 ml of hydrochloric acid (3.1), and connect the flask to the apparatus. Turn the three-way cock (5) so that the tube (1) connects with the outside. Using the mobile tube (2), which is filled with coloured sulphuric acid (3.3) and connected to the graduated tube (1), bring the level of the liquid up to the zero mark. Turn the cock (5) in order to connect up tubes (1) and (3) and check that the level is at zero.\nRun the hydrochloric acid (3.1) slowly over the portion of the sample, tilting the flask (4). Make the pressure equal by lowering the tube (2). Shake the flask (4) until the release of carbon dioxide has stopped completely.\nRestore pressure by bringing the liquid back to the same level in tubes (1) and (2). After a few minutes, when the volume of gas has become constant, take the reading.\nCarry out a control test in the same conditions on 0,5 g of calcium carbonate (3.2).",
