Summary Researchers typically use a batch reactor to study reaction kinetics under ideal conditions. This experiment was carried out in other to study effect of temperature on reaction rate constant and also to study the effect of the reaction rate constant in a batch stirred tank reactor its important in chemical industry because it is used to determine the effect of temperature on reaction rate constant; it is also used in chemical and process industry for solids dissolution‚ product mixing‚ chemical

Sodium Bromide which is slightly toxic if inhaled or ingested may cause serious eye damage if in contact. Sodium Iodide may cause serious eye damage‚ corrosion or irritation causes skin irritation. Silver Nitrate may cause skin corrosion or irritation also may cause severe skin burns and eye damage‚ very flammable keep away from heat‚ sparks‚ open flames‚ and hot surfaces

atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic compound Covalent: nonmetal & nonmetal Covalent bonds are shared; Ionic bonds are distributed Covalent bonds are stronger than Ionic bonds Ionic Compounds: Ionic compounds consist of positive and negative ions. The ions are held together by strong attractions between the oppositely charged ions‚ called ionic bonds Properties of ionic Compounds: The physical and chemical

association of molecules of a solvent with molecules or ions of a solute. As ions dissolve in a solvent they spread out and become surrounded by solvent molecules. Example: As an ionic compound dissolves‚ such as NaCl‚ the ions become surrounded by the solvent‚ say H2O(water) molecules. The ions are said to be ’solvated’ as they become surrounded by the solvent‚ similar to a hoard of bees surrounding a nest. The solvation process helps stabilize the ions in solution and prevents cations and anions from

positive electrode is called the anode and the negative electrode is called the cathode. d) For electrolysis to occur the electrolyte must be in liquid form so that the ions are free to move. e) In electrolysis the negative ions move towards the anode. When they get there they lose electrons to form neutral atoms. The positive ions move towards the cathode. When they get there they gain electrons to form neutral atoms Electrolysis is the process by which ionic substances are broken down into simpler
