Page 10: ...r This works on the principle that a float will sink further into a liquid of low specific gravity than of high specific gravity because the latter is denser and provides greater support USING THE HYDROMETER From one of the cells draw acid into the barrel until the hydrometer float moves freely Now read the specific gravity at the point where the scale emerges from the acid Afterwards make sure th...
