Question

what is a density bottle? Explain the procedure how to use it to measure the volume of the given liquid?​

Answer 1

Answer:

Density bottles are mainly used to determine the density of liquids of moderate viscosity. They are not volumetric instruments, however, they are calibrated 'to contain' as in the case of volumetric flasks. Density bottle with stopper.

Explanation:

• Determine the weight of the dry and empty density bottle.
• Fill the density bottle with liquid, avoiding bubbles. The ground neck should be covered to about 1/3.
• In a thermostatic bath, adjust the temperature of the bottle and contents to 20 °C.
• Align the stopper respectively, the thermometer of the density bottle according to the marking, and insert carefully. The capillary tube fills up and the displaced liquid comes out.
• Carefully dry the outer surfaces of the stopper (respectively, the side capillary) and the density bottle with tissue.

ATTENTION: Be careful not to remove any liquid from the capillary. The sample liquid must be exactly level with the upper end of the capillary.

Thank you.
