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 along

LabMr.P/Pd. 63/17/14 Osmosis and Diffusion Lab Osmosis is a process where molecules pass through a semi permeable membrane from a less concentrated solution into a more concentrated one‚ equalizing the concentrations on each side of the membrane. Diffusion is the spreading of something more widely.During the osmosis and diffusion lab I tested what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The
