Are you ready to discover 'photosynthesis in elodea lab'? You will find the answers here.
This lab involves the qualitative measurement of the changes fashionable carbon dioxide assiduity associated with some respiration and photosynthesis in the bracing water plant Genus Elodea. Bromthymol blue is used as AN indicator for the presence of CO2 in solution. When CO2 dissolves fashionable water, carbonic virulent is formed. A bromthymol blue result, acidified to pH by the accession of carbon dioxide produces a fearful color. The blue-blooded color is restored when the Carbonic acid gas is removed and the pH becomes higher than Data file Size: 235KBPage Count: 16
