WebFill the tube to about 2 cm from the top with the universal indicator solution. Then clamp the tube vertically. It is important to leave a space above the liquid in the tube so that there is an air bubble – this helps the mixing in step 8. Add 3-4 drops of the hydrochloric acid solution. The top few centimetres of the liquid should turn red. WebMar 17, 2015 · Measuring Apparatus A number of pieces of chemistry glassware are used to accurately measure volumes; the most obvious being the graduated cylinder, or measuring cylinder, which can come in a variety of sizes. For measuring volumes of solutions more precisely, a volumetric pipette can be used. WebThe relationship between the volume of a gas and the pressure it exerts can be studied by adding mercury to a J-tube until the height of the mercury is equal on both sides and a sample of gas is trapped. The pressure in the closed portion of the tube now equals atmospheric pressure. formation chu bordeaux
