the effect of concentration of acid on the rate of diffusion in agar blocks? Aim: To investigate how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement of molecules

#55 Affects of Osmosis and Diffusion Introduction: Perfume spreads in a room‚ hands bloat when left in water for too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute‚ the higher the mass of the solution

Maximum Cell Size & Diffusion – Ferris Shaw Research Question: How does the surface area to volume ratio affect the diffusion rate in agar cubes? Hypothesis: The rate of diffusion in directly related to the surface area to volume ratio of cells and is responsible for the efficiency of absorbing nutrients‚ oxygen‚ minerals etc. in the cell. This ratio is specific to cells as they require a ratio that isn’t big enough to take too long to receive the nutrients and oxygen or too small to
