LAB 3.Ø.Ø: do ions flow in definite ratios PURPOSE The purpose of this study is to determine whether ions blend in in definite ratios or non. To observe, and progress to a table of the contrasting ions. QUESTION If bull (II) convert when combine with sodium change at different quantities combine to formulate ions in definite ratios. HYPOTHESIS / PREDICTION I c any up that the ions will combine in definite ratios due to the point that the valance electrons will not be changing passim any chemics; consequently the ions must(prenominal) combine in definite ratios. EXPERIMENTAL DESIGN A proficiency is performed in which horseshit (II) convert and sodium change are lay outd together in mingled exam renders, with various quantities of each chemical and a chemical action should happen. The clock for the two chemicals to entirely react is about five ? go minutes. The temperatures of the solutions, the quantities of the solutions are in all controlled variables. The chemicals are known to form a precipitate. MATERIALS -Safety glasses-10 ml fuzz (II0 sulfate solution -Seven demonstrate thermionic tubes-10 ml sodium carbonate solution -1 scrutiny tube rack- Tap water -Masking Tape -Two ticker Droppers PROCEDURE 1.Placed goggles on face. 2.Numbered the strain tubes from 1 ? 5 and place in test tube rack. 3.Washed the test tubes with tap water. 4.Using the eyedropper, added the get number of copper (II) sulfate to the numbered test tube. 5.
Using the second eyedropper, added the take over number of sodium carbonate to the numbered test tubes. 6.Swirled test tubes quietly to mix the contents. 7.Allowed the precipitate to cause for 7 minutes. 8.Recorded observations. OBSERVATIONS Table 1.1 Test Tube #(Column 1) Copper (II) sulfate Drops (column2) Sodium Carbonate Drops (Column 3) General Observations- ColourPrecipitate (column4) 119Light BlueLittle 237Medium BlueMedium 355Dark BlueLarge 473Medium BlueMedium 591Light BlueLittle Double Displacement: CuSO4 (aq) + NaCO3...
