The effect of varying molecular weights on the rate of diffusion essay

How Does Molecular Weight Affect the Rate of Diffusion?

Partial rate is computed by deducting the diameter of coloured country instantly di-1 before the diameter of coloured country at a given clip d1 divided by the clip when d1 was measured t1 minus the clip instantly before t1 ti — 1.

The values of the entire distances and ratios were calculated so. The higher the difference between the two concentrations, the faster the rate of diffusion. Inhis work was subsequently published in the Philosophical Magazine. If the entire force per unit area in the chamber is besides decreased.

The distances in cm form both ends of the glass tubing until the position where it was marked, were measured. While methylene blue had the smallest, potassium permanganate had the largest diameter of 18 mm then potassium dichromate of 16 mm after 30 minutes. After a fixed three minute interval within the 30 proceedingss.

Diffusion is the procedure by which substances spread from parts of high concentration to the parts of low concentration until there is equilibrium.

We must bear in head that K permanganate KMnO4 had the lowest molecular weight while methylene blue had the highest molecular weight ; nevertheless.

The molecular weight of NH4OH Time besides had an consequence to the rate of diffusion because in the first few proceedingss. This relationship is presented in Figure 4. This is because a bigger molecule requires greater force in able to move such particle, unlike the smaller particle which merely needs a lesser force for it to move Meyertholen, Table 2 The table2 shows result of how fast Potassium permanganate, Potassium dichromate and methylene blue diffused after thirty minutes with the interval of three minutes per measurement.

These values were then plotted, evaluated and construed. NH4OH have the opposite situation. The H2O agar-gel apparatus was made up of a petri dish incorporating the gel with three Wellss. After the 30 minute mark, methylene blue had the smallest diameter of 9 mm, potassium dichromate with 16 mm and potassium permanganate with 18 mm had diffused the slowest with its are methylene blue rate of diffusion of 0.

The rate of diffusion has a direct relationship with the concentration gradient, pressure and temperature. During the process of diffusion, the substance moves from an area of higher concentration to an area of lower concentration. A two pess glass tubing was placed horizontally on a ring base as shown in Fig.

Afterwards, it was observed that a white smoke appeared in the glass tubing and the position was marked. The calculated data were organized into table. Both cotton balls were plugged at the same time on both ends of the glass tube.

Methylene blue has the greatest molecular weight consistently appears to have the slowest diffusion rate. Specifically, it aimed to: Two cotton balls of the same size was obtained. A two feet glass tube was placed horizontally on a ring stand as shown in Fig.

Hydrochloric acid HCl has a molecular weight of Molecular weight could so be defined as the mass of a molecule that is comparative to the mass of atom.

The information was so recorded into a tabular array. This may then serve as one of the factors that affect the rate of diffusion. The Brownian gesture, recognized for the first clip by the Scots phytologist Robert Brown, was elucidated decennaries subsequently by Albert Einstein, the celebrated German-Jewish physicist.

The data was then recorded into a table. Three bottles with dropper incorporating the substances and a petri dish with agar — H2O gel were given to each group. A two pess glass tubing was placed horizontally on a ring base as shown in Fig.

There are inconsistencies that are present.

The H2O agar-gel apparatus was made up of a petri dish incorporating the gel with three Wellss. This survey aimed to find the consequence of molecular weight on the rate of diffusion of sbustances via the agar-water gel trial.

New hampshire4OH with the lower molecular weight at Methylene blue which has the greatest molecular weight of the three shows a trend that is very inconsistent and very slow when it comes to the rate of diffusion.

The pattern concerning the rate of diffusion could not be exactly determined, yet there was continuous change. The diameter at 0 minute was then measured and recorded. After the 30 minute grade.

Consequently, gas diffusion coefficients are directly proportional to the 3/2 power of temperature and inversely proportional to the square root of molecular mass. Diffusion in Liquids Molecules in a liquid almost immediately stop moving after collisions because of viscosity, a liquid’s resistance to motion.
