Chem Lab, do ions combine in definite ratios.

LAB 3.Ø.Ø: do ions shuffle in defined ratios point The purpose of this investigating is to determine whether ions combine in definite ratios or non. To observe, and shit a table of the different ions. disbelief If bull (II) convert when combine with sodium change at different quantities combine to body-build ions in definite ratios. scheme / 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 proficiency is per get toed in which horseshit (II) sulfate and sodium carbonate be placed together in diverse exam renders, with various quantities of each chemical and a chemical reaction should happen. The epoch for the two chemicals to entirely react is about five ? ex minutes. The temperatures of the solutions, the quantities of the solutions are in all controlled var iables. The chemicals are known to form a precipitate. MATERIALS -Safety glasses-10 ml copper (II0 sulfate solution -Seven present pipeworks-10 ml sodium carbonate solution -1 test tube rack- Tap water -Masking Tape -Two Eye Droppers PROCEDURE 1.Placed goggle 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 divert flesh 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 gently to mix the contents. 7.Allowed the precipitate to try for 7 minutes. 8.Recorded observations.
