Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions‚ and write net ionic equations for precipitation reactions‚ as well as to identify spectator ions‚ perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate‚ copper (II) nitrate‚ iron (III) nitrate‚ barium

HCl SUMMARY p 531 p 532 practice # 1‚ 2‚ 3. The Autoionization of Water - 2 molecules may collide and one molecule accepts a proton from the other – see p 532 - equilibrium of the reversible reaction – can write the constant - Kw = [H +] [OH –1 ] = (1.0 x 10 –7 )2 = 1.0 x 10 –14 - Kw changes at different temp ( remember concept from ch 7 ) - so pH of pure water changes with diff temp - but pure water always neutral since # protons = # hydroxide ions Strong Acids - ionize more

In the fume hood‚ approximately 2g of Ca(OH)2 was dumped from a vail into a 250ml beaker. To avoid any left-over Ca(OH)2 inside the vail‚ certain amount of distill water wad added to it‚ and the vail was shook several times after the lid was closed. Pouring the solution in the vail into the beaker‚ and add distill water until it reached the 100ml line. Then‚ the beaker was put on top of a magnetic stir with a magnetic stir bar placed in it. Turning on the magnetic stirrer and allowing the stir bar
