exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl ̄→AgCl+NO3 ̄+Na+ Net: Ag+ (aq)+Cl ̄ (aq)→AgCl(s) Ions present in the solution but

Ocean County College Department of Chemistry Identification of Metallic Ions Purpose: The purpose of this lab exercise was to perform and observe the flame tests of some alkali and alkaline earth metal ions. When electrons in metallic ions are grounded‚ their configuration is stable. In other words‚ the loosely bound electrons in the valence shell of the atom are satisfied at their “low” energy state. They do not require to be balanced by emitting any type of radiation or receiving any

WHAT IS HARM REDUCTION? Harm reduction is a set of practical strategies intended to reduce the negative consequences of high risk behavior such as over drinking or drug abuse. Harm reduction is a non judgmental approach that attempts to meet people where they are at with their drinking or drug abuse. Instead of demanding perfect abstinence‚ this pragmatic approach is supportive of anyone who wishes to minimize the harm associated with a high risk behavior such as drinking or drug abuse. Harm

experiment of making borneol from camphor (FIGURE-3) is performed in two different methods‚ Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction‚ to compare the relative product ratio of borneol to isoborneol. The concept of reduction and also oxidation‚ the opposite procedure of reduction‚ deals mostly with electron transfer between atoms. It will not be elaborated here‚ but the reduction procedure involved in this experiment is basically adding hydrogens and losing the carbon-oxygen double
