sodium chloride = sodium nitrate + lead chloride Neutralization is the reaction between an acid and alkali/base/carbonate . One example of neutralization is Sulphuric acid + magnesium oxide = magnesium sulphate + water Sodium hydroxide is a corrosive metallic base‚ and it is also called caustic soda. Nowadays‚ it is made along with hydrogen and chlorine‚ using the chloralkali process (any process that produces chlorine or a related oxidizer ) Electrolysis of a solution of sodium chloride (common

part 1 ‚ we observed the shift in equilibria of two aqueous solutions of Copper and Ammonia then Nickel and Ammonia. In part 2‚ we focused on cobalt ions in the presence of chloride ions as well as the precipitation of silver nitrate and sodium carbonate. In the last part of the experiment we utilized a solution of Cobalt chloride and compared the color at room temperature and then again in a container of boiling water. Physical Data: No physical Data was applicable to the experiment. Chemical Equations:

Chemistry Abstract This experiment was performed to determine the rate constant k‚ for hydrolysis of tertiary butyl chloride to tertiary butanol. The solvent system for this reaction is 45% isopropyl alcohol and 55% water. The rate of hydrolysis of t-butyl chloride is measured by the decrease in the concentration of this reagent with time. The rate of decomposition of t-butyl chloride must be equal to the rate of formation of hydrochloric acid. The rate of hydrochloric acid formation was measured

Reaction of acids with metal: Acids give hydrogen gas along with respective salt when they react with a metal. Example:- Hydrogen gas and zinc chloride are formed when hydrochloric acid reacts with zinc metal. Hydrogen gas and sodium chloride are formed when hydrochloric acid reacts with sodium metal. Hydrogen gas and iron chloride are formed when hydrochloric acid reacts with iron. Hydrogen gas and zinc sulphate are formed when zinc metal reacts with sulphuric acid Test for

counterparts‚ require reactive electrophiles with significant carbocation character. One of the most common ways to alkylate an aromatic ring is to use an alkyl chloride electrophile that is activated by the addition of aluminum or iron trichloride. The metal chloride serves as a Lewis acid‚ accepting electron density from the alkyl chloride. This has the effect of magnifying the carbon-chlorine dipole‚ making the carbon end more electropositive - and thus more electrophilic – even to the point where

components in a mixture‚ specifically sodium chloride and silica‚ and find the correlating percent composition of each. Abstract: This experiment consisted of the separation of sodium chloride and silica. The mixture was separated by extracting the sodium chloride with water and drying both substances. Adding water to the mixture‚ stirring‚ then decanting the resulting liquid twice extracts the dissolved sodium chloride from the silica. Heating both sodium chloride and silica separately provides the mass

and our reactions to it. Since sodium-chloride is nontoxic our response to the dosage was measured by taste. This same method can be seen in medical studies for new drugs. Instead of students the doctors use mice and they test for the mice’s reaction to the medicine. Instead of testing the mice’s taste‚ they look for negative/positive side effects the mice might have Intro Different salts can elicit all five basic tastes‚ e.g.‚ salty (sodium chloride)‚ sweet (lead diacetate‚ which will cause

In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are based on the mass of a product‚ this procedure is classified
