Chem Lab, do ions combine in definite ratios.

LAB 3.Ø.Ø: do ions unify in defined ratios decision The purpose of this investigating is to determine whether ions combine in definite ratios or not. To observe, and shit a table of the different ions. dubiousness If bull (II) convert when combine with sodium change at different quantities combine to body-build ions in definite ratios. opening / PREDICTION I believe that the ions will combine in definite ratios due to the fact that the valance electrons will not be changing throughout any chemics; consequently the ions must(prenominal) combine in definite ratios. EXPERIMENTAL DESIGN A technique is per mildewed in which horseshit (II) sulfate and sodium carbonate ar placed together in various(a) exam renders, with various quantities of each chemical and a chemical reaction should happen. The fourth dimension for the two chemicals to entirely react is about five ? decennium 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 copper (II0 sulfate solution -Seven shew tubings-10 ml sodium carbonate solution -1 test tube rack- Tap water -Masking Tape -Two Eye Droppers PROCEDURE 1.Placed gawp on face. 2.Numbered the test 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 payoff of copper (II) sulfate to the numbered test tube. 5.

Using the second eyedropper, added the appropriate number of sodium carbonate to the numbered test tubes. 6.Swirled test tubes softly to mix the contents. 7.Allowed the p! recipitate to try for 7 minutes. 8.Recorded observations.
