Beaker Used to hold and heat liquids. They quickly came up with the Bunsen burner which is still a critical piece of lab equipment today. If the acid has not been hot enough excess acid can co-exist with copper oxide.

A Bunsen burner is a type of gas burner that is used in many chemistry procedures in a laboratory setting. The Bunsen burner is named after German chemist Robert Bunsen. Bunsen and Kirchoff were able to work out that by using an external light source and a prism they could separate the wavelengths of emission spectra in these flames and so the spectroscope was born.

Study sets textbooks questions. It is used in the chemistry lab for mixing heating and stirring liquids. In late 1852 Bunsen became the successor of Leopold Gmelin at the University of HeidelbergThere he used electrolysis to produce pure metals such as chromium magnesium aluminium manganese sodium barium calcium and lithiumA long collaboration with Henry Enfield Roscoe began in 1852 in which they studied the photochemical formation of hydrogen.

If desired the experiment can be extended to isolate dry samples of sand and salt. It is not a large plume nor is it orange. It is used to heat substances to combust substances and to sterilize.
