HW: p.491(1-7) 1. Compare the general properties of acids with the general properties of bases. Acids: Aqueous solutions of acids have a sour taste. Acids change the color of acid-base indicators. Some acids react with active metals and release hydrogen gas‚H2. Acids react with bases to produce salts and water. Acids conduct electric current. Bases: Aqueous solutions of bases taste bitter. Bases change the color of acid-base indicators. Dilute aqueous solutions of bases feel slippery

INTRODUCTION: The purpose of this experiment is to measure the formation constant of the tetraamminecopper(II) ion by colorimetry. Anhydrous copper sulfate (CuSO4) is white‚ which means that it does not absorb light in the visible region of the spectrum. The hydrated copper sulfate (CuSO4 - 5H2O) is blue. The structure of the compound can be represented more accurately as Cu(H2O)4 SO4 - H2O where four water molecules are bound to the copper ion and the fifth is a water of crystallization. The
