The standardization of KMnO4 solution, if the magnetic stir bar was dropped into the flask, and some FAS solution splashed out, how would the calculation for the molarity of KMNO4 be affected? The calculated molarity of KMnO4 would be: Lower. Less FAS would need less MnO4-, therefore, the reduced volume would result in a smaller M. Unchanged. Lower. More FAS would need less MnO4-, therefore, the increased volume would result in a smaller M. Higher. Less FAS would need less MnO4-, therefore, the...
