      - Testing for purity
        
        color (absorbance) - Light intensity (lux)
        
        Simply point Light sensor at Solution
        
        Make sure to keep the same distance
        
        Dont use absorbance, advice by student
        
        Viscosity
        
        Measure density of sphere
        
        Measure Density of oil
        
        Measure Distance the sphere travelled
        
        Viscosity = n = 2(deltap)ga^2 / 9v
        
        g = acceleration due to gravity (9.8m/s^2)
        
        deltap = density of sphere - density of fluid
        
        a=radius of sphere
        
        V= velocity (cm/s)
