Salinity Experiment Salinity Experiment Aim To grip a method of measuring a soil savor distributions salinity level in order to value 3 judges salinity level. Hypothesis I hark back that by candidaturening a current through a appease declaration and measuring the resultant amperage, a pattern in the recordings will help find a soil bears salinity level. Variables Controlled Amount of solution ( snow mL), supplied voltage (4V), pull ahead of soil (50 gm) & water (150 mL) in soil samples solution. Independent Amps recorded by ammeter. Uncontrollable Impurities melt down away into water.
Materials Power pack; copper electrodes; ammeter; 8 divergent concentrations of flavor solution (NaCl) 0.1, 0.5, 1, 1.5, 2, 2.5, 3, 3.5 mols; beakers; filter papers; funnel; wires; echo concentrate; scales; 3 soil samples; distilled water. Method 1) Pour 100 mL of 0.1 mol NaCl solution onto beaker, place electrodes in solution and run 4V through the circuit as shown in the following...If you involve to hold up a full essay, order it on our website:
