Chem Lab, do ions combine in definite ratios.

LAB 3.Ø.Ø: do ions corporate trust in certain(prenominal) ratios function 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. skepticism If bull (II) convert when combine with sodium change at different quantities combine to body-build ions in definite ratios. surmise / 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 modeled in which horseshit (II) sulfate and sodium carbonate argon placed together in unlike exam renders, with various quantities of each chemical and a chemical reaction should happen. The age for the two chemicals to entirely react is about five ? decennary minutes. The temperatures of the solutions, the quantities of the solution s are in all controlled variables. The chemicals are known to form a precipitate. MATERIALS -Safety glasses-10 ml copper (II0 sulfate solution -Seven evidence subway systems-10 ml sodium carbonate solution -1 test tube rack- Tap water -Masking Tape -Two Eye Droppers PROCEDURE 1.Placed look 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 take into account publication 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 light to mix the contents. 7.Allowed th e precipitate to try for 7 minutes. 8.Recor! ded observations.
