What Are Beakers and How to Use Them?

Introduction to Beakers

• The video introduces beakers, explaining their purpose and usage in chemistry. Beakers are vessels of various volumes, typically made of glass or plastic, with graduated markings and a spout for pouring.

Characteristics of Beakers

• Beakers are transparent, allowing visibility of the contents at all times. The graduation marks provide an approximate volume measurement but are not exact due to temperature changes affecting accuracy over time.

• The spout on top is designed to facilitate pouring liquids, minimizing spills and material loss.

Types of Beakers and Their Uses

• Short beakers are primarily used for transferring liquids and preparing solutions. They simplify the introduction of solids, stirring, and pouring processes.

• Long beakers are preferred for decantation as they clearly show phase separation. They also aid in electrolysis since the electrode is more submerged in the solution, making color change during titrations easier to observe.
