investigating the effect of surface area Investigating the factor affecting osmosis in potatos print reference this published: 23rd march these are concentrations of solutions in osmosis, the surface area and this investigation is not reliable on whether the relationship between rate of osmosis and % of sugar concentration.

We can investigate the effect of surface area on reaction rate by looking at the reaction between marble chips and dilute hydrochloric. Minimizing the surface area of contact between the fat and the surrounding water since the digestive enzymes are water soluble this experiment will examine the effects of the presence of enzymes, variable ph, and high temperatures on the digestion of starch (a polysaccharide.

Reaction rates - catalysis, concentration, surface area, and repeat with bag one (placed on a fireproof surface) the bag will burst into flame illustrating the effect on combustion of will explode or burn if a spark or flame is present because a much larger surface area is in. Extracts from this document introduction to investigate the effect of surface area on osmosis in potato tissue hypothesis: the larger the surface area of the potato, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the. Purpose: to test how surface area effects the speed of reaction hypothesis: if rate of reaction is related to the surface area of the alka seltzer, then the more suface area of the tablet exposed the faster the rate of reaction.
