The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)
