WebFor gases that are not particularly soluble in water, it is possible to collect the evolved gas by displacement of water from a container. The setup for the collection of a gas over water involves a container in which the reaction takes place and a gas collection container filled with water and inverted in a reservoir of water. WebDetermining the gas constant "R" by measuring the properties of hydrogen gas collected in a gas buret is well suited for comparing two approaches to uncertainty analysis using a single data set. The brevity of the experiment permits multiple determinations, allowing for statistical evaluation of the standard uncertainty u[subscript "R"] within a laboratory … Web18 sep. 2024 · Suppose we now collect hydrogen gas, H2(g), over water at 21 C in a vessel with total pressure of 743 Torr.
