Question: A funnel containing a relatively wide nozzle (opening), used to deliver solids without making a mess, essential in precise preparation of solid-liquid solutions. Which of the following options is the best match for this tool?
Final answer: Among the given options, a Powder Funnel is the best match for the described tool. It helps in efficient and mess-free delivery of solids into solid-liquid solutions due to its wide nozzle.
Explanation:
Powder Funnel: The tool described in the question is known as a Powder Funnel. It is specifically designed with a wide nozzle to allow for the efficient and mess-free delivery of solids, often used in the creation of precise solid-liquid solutions in a laboratory setting.
Filtration Funnel: Filtration involves the use of HEPA or Membrane Filters to physically separate substances, especially microbes from samples, rather than aiding in the preparation and delivery of solutions.
Separation Funnel: Although used to separate liquids with different densities, a Separation Funnel does not directly relate to the precise delivery of solids into liquid solutions.
Buchner Funnel: Primarily used in vacuum filtration, a Buchner Funnel is not designed for the specific task of delivering solids into liquid solutions without causing a mess.
Distillation: Distillation is a process used to extract and purify substances through heating and cooling but does not directly involve the use of a funnel.
Therefore, among the given options, a Powder Funnel is most fitting. It is the ideal tool for the described use due to its large bore and capacity to limit spillage, making handling of solids easier and helping in managing precise quantities in solid-liquid solution preparation.
