    CHM152LL LAB MANUAL COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS Complexometric Determination of Water Hardness Introduction Complex ions When a neutral molecule or anion (a Lewis base) donates electron pairs and attaches itself to a metal ion center (a Lewis acid)‚ the resulting cluster‚ or complex‚ of atoms becomes a single complex ion. When such complexes form‚ the electron donating groups (called ligands) form coordinate covalent bonds through empty orbitals on the metal ion. An example

    example the presence of salt greatly enhances the rusting of metals. This is due to the fact that the dissolved salt increases the conductivity of the aqueous solution formed at the surface of the metal and enhances the rate of electrochemical corrosion. This is one reason why iron or steel tend to corrode much more quickly when exposed to salt (such as that used to melt snow or ice on roads) or moist salty air near the ocean. [pic] salt will speed up rusting. The more salt you

    an unknown soluble salt sample through a gravimetric method known as precipitation gravimetry. The objective was to accurately and precisely convert the unknown sample containing the chloride analyte to another known solid‚ silver chloride. Once the mass of the known solid is measured‚ the percentage of chloride analyte can be calculated using stoichiometry. The chemical reaction occurring in this particular experiment involved the mixing of silver nitrate and the soluble salt in water containing
