    Introduction A complex ion consists of a metal ion with Lewis bases attached to it. These Lewis bases form strong coordinate covalent bonds with the central complex ion in which both electrons of the bond are donated by the Lewis base. The Lewis bases that form this complex are referred to as ligands and they are typically either neutral molecules or anions. Polydentate ligands have multiple lone pairs of electrons that enable them to bond multiple atoms to the central metal atom. The stability

    width of the specimen. The tests were performed at a 2 mm/min. The samples were connected to the clamps of the machine from the both sides. Afterwards‚ the tensile forces were applied from the ends and the overload failure mode was examined. Furthermore‚ the test results were measured as the area under the load-displacement curve up to the peak load. The failure mode was determined from the failed samples. 2.3 Metallography The macroscopic examination also termed as macro test were used to assess the

    UNKNOWN SAMPLE #97 COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS DR. BUDRUK CHM 152 LL SEAN MARKIS 4 FEBRUARY 2015 Introduction Using a Lewis base neutral molecule to donate electron pairs (ligands) to a Lewis acid metal ion center to form a single cluster (complex) ion. When the complex ions forms with a metal ion (chelation) the ligand used is called the (chelating agent). EDTA acts as a great chelating agent due to the Nitrogen and Oxygen donating an electron pair to the

    Alana Rogers Date of experiment:11-20-13 Date submitted: 11-23-13 Determination of Water Hardness Using a Titrator Purpose: This purpose of this experiment was to determine the hardness of the local water supply. Be familiar with using a titrator. To tell wether your water is hard or soft. Hard water however does not create a threat‚ but is bad for your pipes causing them to crust. To measure water’s “softness” you are truly measuring the amount of CaCO3 in the water. Procedure: Assemble
