Salinity Experiment Salinity Experiment Aim To take in a method of measuring a soil samplings salinity level in order to measure out 3 judges salinity level. Hypothesis I hypothecate that by candidaturening a current through a while resolving and measuring the resultant amperage, a pattern in the recordings will help find a soil come ups salinity level. Variables Controlled Amount of solution ( coke mL), supplied voltage (4V), fare of soil (50 gm) & water (150 mL) in soil proves solution. Independent Amps recorded by ammeter. Uncontrollable Impurities expire away into water.
Materials Power pack; copper electrodes; ammeter; 8 various concentrations of flavor solution (NaCl) 0.1, 0.5, 1, 1.5, 2, 2.5, 3, 3.5 mols; beakers; filter papers; funnel; wires; take back 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 indispensableness to hold up a full essay, order it on our website:
