Question

What is a density bottle? How is it used to find the density of a liquid?

Answer 1

Density bottles are mostly used to calculate the density of medium viscosity liquids. They aren't volumetric instruments, but they are calibrated 'to contain,' much as volumetric flasks are. A small glass bottle with a glass stopper at the neck is known as a Density bottle.

Complete step by step solution:
A small glass bottle with a glass stopper at the neck is known as a Density bottle. A fixed amount of liquid may be stored in the bottle. The bottle's volume is usually 25 ml or 50 ml. The stopper has a small hole in it. Excess Liquid rises through the hole and flows out when the container is full of liquid and the stopper is mounted. Density bottles are mostly used to calculate the density of medium viscosity liquids. They aren't volumetric instruments, but they are calibrated 'to contain,' much as volumetric flasks are.
When dealing with substances, relative density is used in many cases, such as specific gravity, in which the density of any mass (liquid or solid) such as oil or wood is compared to the density of water. It offers the following benefits:
Gives us a clearer idea of the substance's consistency, such as if it is heavier than the same amount of water.
When dealing with a binary mixture, where two substances communicate with one another, this tool provides valuable information. As compared to the density of water, the relative density of oak wood is 0.75 (important to remember that relative density has no units), so we can reasonably conclude that oak wood would float rather than sink.
Note: A density tube, also known as a Pycnometer, special gravity bottle, or pycnometer, is a measurement device that is used to determine the density of liquids. Glass is typically used to make a density bottle. Density bottle is also composed of high-density polyethylene or polypropylene.
