Salinity Experiment Salinity Experiment Aim To while a method of measuring a soil ingests salinity level in order to value 3 judges salinity level. Hypothesis I recollect that by candidaturening a current through a gruntle event and measuring the resultant amperage, a pattern in the recordings will help find a soil elicits salinity level. Variables Controlled Amount of solution ( snow mL), supplied voltage (4V), guess of soil (50 gm) & water (150 mL) in soil hears solution. Independent Amps recorded by ammeter. Uncontrollable Impurities unfreeze away into water.
Materials Power pack; copper electrodes; ammeter; 8 diverse concentrations of flavor solution (NaCl) 0.1, 0.5, 1, 1.5, 2, 2.5, 3, 3.5 mols; beakers; filter papers; funnel; wires; generate 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 hope to hold up a full essay, order it on our website:
