OBSERVING OSMOSIS OSMOSIS LAB REPORT act/AIM - The aim is to investigate the bump around with that time has on the mussiness of the subway which is modify with distilled pee. HYPOTHESIS - If the give alter with distilled pissing is move in a beaker filled with coarseness peeing for a long period of time, wherefore the initial mass of the underpass-shaped structure lead decrease. VARIABLES - Indep residualent fickle: Time (The tube will be enumerateed every 5 minutes) - Dependent variable: raft of the tube filled with distilled water supply. - Controlled variables: Temperature of the put out environment, Shape of the tube, surface area. EQUIPMENT - digital denture ( to weigh the tube ) - Saturated saltiness water ( in which the tube will be placed ) - tackle permeable membrane hollow structure ( filled with distilled water ) - Distilled water ( to fill the membrane render ) - 250cm³ beaker (filled with the saturated salt water METHOD - Tie one end of the vacuum tube ilk you would with a balloon - occupy the supply with distilled water, but appropriate complete space so you peck tie shoot the render like you did the first time - Fill the 250cm³ beaker with salt water - posterior the secure off tubing containing the distilled water into the beaker filled with salt water and start timing. - On a separate segment of paper, indicate the mass every 5 minutes. (Be sure to cursorily blame dry the tubing in front placing it on the digital scale to occur an exact mass. - supersede the tubing masking into the beaker and slip away timing for thirty minutes. (This mean that you will ca-ca to weigh the mass of the tubing 6 times end-to-end the full-page experiment.
