(a) A solution of higher surface tension is capable of sustaining droplets oflarger sizes. Methyl ethyl ketone has a lower surface tension than neatwater. For iron solutions of the same concentration in both solvents, whichone will give rise to a higher absorbance? Explain.
(b) A calibration is performed with a standard solution of iron in water. Aniron solution in methyl ethyl ketone is analysed based on this calibrationfunction. Is it likely to yield an accurate result? or would the result be toohigh or too low? Explain.
