    corrodes and eventually crumbles when reacted with acid rain(H2SO4). Not only is the Taj Muhal suffering‚ but also other historic landmarks across the world. This is a metathesis (Double Replacement) reaction where (CaSO4”s”) is a produced as cations(+) and anions(-) exchange partners and pair such as the following: CaCO3+H2SO4 CaSO4+ H20+CO2. In general terms‚ this is the simplest form of what’s going on in a metathesis reaction: AX + BY AY + BX. A metathesis reaction will result in one or more of

    An atom is a neutral particle containing an equal number of protons and electrons Molecule: a group of two or more atoms held together by chemical bonds Ion: an atom that has a positive or negative charge cation: lost electrons; takes on a positive charge (more protons than electrons) anion: gained electrons; takes on a negative charge (more electrons than protons) Chemical Bonds: form between atoms because of the interaction of their electrons electronegativity: the ability of an atom to attract

    Introduction The experiment is testing for the formation of precipitates caused by different limiting reactants. A precipitate results in a solid formed by an ionic compound. Calcium nitrate and copper sulfate will be added to separate beakers with approximately half of the solutions from the Büchner funnel system of each trial to test for the formation of precipitates. The limiting reactant is the reactant that will run out first in the chemical reaction. It is important to recognize which chemical

    FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

    modern theory‚ the loss of electrons is called oxidation. * The total number of electrons gained in a reaction must equal the total # of electrons lost. Oxidation States * Metals and monatomic anions tend to lose electrons (become oxidized)‚ whereas non-metals and monatomic cations tend to gain electrons (become

    Experiment 5 COMMON ION EFFECT MALUBAY‚ Justin Damian PADRILLAN‚ Hazel Rose CD2‚ Group 5 Ms. Sarah Sibug 6 April 2013 ------------------------------------------------- ------------------------------------------------- I. ABSTRACT The common ion effect occurs when a given ion is added to an equilibrium mixture that already contains that ion‚ and the position of equilibrium shifts away from forming more of it. This paper is a follow-up of the experiment which aims to determine the common-ion effect

    H2O R-SO31- ‚ H3O+ (1) R represents the large insoluble resin molecule to which a sulfonic acid group is chemically bonded‚ H3O+ represents acid hydronium ion bound to the resin sulfonate ion. This particular type of resin is called a cation exchange resin for reasons described later‚ and the chemical form of the resin represented in Equation 1 is called the acid form for obvious reasons. When a slurry of the resin in water is poured into a vertical glass or plastic column equipped with

    The band gap value of the DBAP molecule was calculated as 5.60 eV‚ which indicates that the DBAP molecule has stable molecular structure and the value is comparable with the band gap energy value of the reported bio-active molecules [16]. The higher hardness and lower softness value indicates the stability of the DBAP molecule. The obtained lower chemical potential and electrophilicity index values are comparable with the potential bioactive molecules [14‚ 16]. DOS spectrum was also simulated by
