Question

(A) Calorimeter
(B) Geiger counter
(C) Burette
(D) Funnel
(E) Bunsen Burner

Answer 1

In order to answer this question, to know which one can be lined with moist filter paper to catch insoluble solids, we will explain why that instrument satisfies the given statement of the question, and we will also explain more about it.

Complete answer:
Funnel can be lined with moist filter paper to catch insoluble solids. A funnel is a pipe with a wide, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, spillage would occur.
A funnel is a tube or pipe that is wide at the top and narrow at the bottom, used for guiding liquid or powder into a small opening.
Funnels are usually made of stainless steel, aluminium, glass, or plastic. The material used in its construction should be sturdy enough to withstand the weight of the substance being transferred, and it should not react with the substance. For this reason, stainless steel or glass are useful in transferring diesel, while plastic funnels are useful in the kitchen. Sometimes disposable paper funnels are used in cases where it would be difficult to adequately clean the funnel afterwards.
There are many different kinds of funnels that have been adapted for specialised applications in the laboratory. Filter funnels, thistle funnels (shaped like thistle flowers), and dropping funnels have stopcocks which allow the fluids to be added to a flask slowly. For solids, a powder funnel with a wide and short stem is more appropriate as it does not clog easily.

So, option D is correct.
