Osmosis Essays

Hypothesis: The potato will lose weight and become shrank when they are put in salt solutions. The higher concentrated the solution, the more the potato shrinks. Osmosis is the passage of water at a cellular level from an area of low solute concentration to an area of high solute concentration …

1. Design 1.1 Defining the problem Research Question Have you ever accidentally cooked a solanum tuberosum (potato) in high sodium chloride (salt) concentrated water? What was the result? This experiment is to consider how salinity influences osmosis in potato cells. By changing the concentration of salt (0%, 0.2%, 0.4%, 0.6%, …

Osmosis is the transport of water molecules from an area of their high concentration (hypertonic solution) to an area of their low concentration (hypotonic solution) through a semi-permeable membrane1 such as cell membrane. This tendency, when water molecules move from one region to another is called the water potential. Osmosis …

Defining problem and selection variables Purpose: The purpose of the experiment is to show how varying the concentration of salt solution affects osmosis in a potato piece. Background: * Osmosis: Diffusion of water molecules across a membrane from high concentration to low concentration. (Biology, Sixth edition – Campbell, Reece) * …
