The sodium benzoate can be converted to benzoic acid, C6H5COOH, by the addition of dilute hydrochloric acid. Reaction II C6H5COONa + HCl C6H5COOH + NaCl Method • Place 4.5 g of ethyl benzoate in a flask and add an excess of sodium hydroxide solution. • Heat the mixture under reflux for fifteen minutes. • Distil off the ethanol formed.

A soap is a sodium or potassium salt of some long chain carboxylic acids (fatty acid). Sodium salts of fatty acids are known as hard soaps and potassium salts of fatty acids are known as soft soaps. Hard soaps are prepared from cheap oils and fats and sodium hydroxide. They contain free alkali and are used for washing purposes.

The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.

B. Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide? Aqueous sodium hydroxide is a very strong base. By using a very strong base, it can cause the reaction to proceed with the E mechanism and gives us undesirable alkaline products. 2. Some 2-methyl-2-butane may be produced in the reaction as a by-product.

Crude oil coats the water's surface in the Gulf of Mexico after the Deepwater Horizon oil rig sank following an explosion. The leak was a mile below the surface, making it difficult to estimate the size of the spill. One liter of oil …

View this answer. It is not advised to wash crude halide products with the help of aqueous sodium hydroxide. This is because aqueous sodium hydroxide is a strong base.... See full answer below.

Aqueous sodium bicarbonate was used to wash the crude n-butyl bromide.. a. What was the purpose of this wash? Give equations. b. Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide?

Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide? Aqueous sodium hydroxide is a very strong base. By using a very strong base, it can cause the reaction to proceed with the E2 mechanism and gives us undesirable alkene products. 2. Some 2-methyl-2-butene may be produced in the reaction as a by-product.

Because any water contaminating the alkyl halide, will likely also contaminate the distillate. Water often azeotropes with organic compounds, sometimes at much lower temperatures than 100 ""^@C. Thus, it makes sense to dry the alkyl halide before distillation, especially if the halide is going to be used for say a Grignard or lithium reagent reaction.

Drilling muds are usually classified as either WBMs or OBMs, depending upon the character of the continuous phase of the mud. However, WBMs may contain oil and OBMs may contain water [].OBMs generally use hydrocarbon oil as the main liquid component with other materials such as clays or colloidal asphalts added to provide the desired viscosity together …

Draw the structures of these by-products and give mechanisms for their formation. 4. Aqueous sodium bicarbonate was used to wash the crude n-butyl bromide. (a) What was the purpose of this wash? Give equations. (b) Why …

Aqueous sodium bicarbonate was used to wash the crude n-butyl bromide. a. What was the purpose of this wash? Give equations. b. Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide? 5. Look up the density of n-butyl chloride (1-chlorobutane). Assume that this alkyl halide was prepared instead of the bromide.

1. What is the purpose to wash the crude t-pentyl chloride with sodium bicarbonate. Why would it be undesirable to wash the crude halide with aqueous sodium hydroxide? 2. Why must the alkyl halide product be dried carefully with anhydrous sodium sulphate before the distillation? POST-LAB QUESTION . 1.

Give equations. Aqueous sodium bicarbonate wash is to neutralize the trace amounts and present in solution due to hydrolysis of alkyl halide. The bicarbonate is a weak base that will react and neutralize the HCl. The equation is HCL + NaHCO 3 H 2 CO3 + NaCl-Why is it undesirable to wash the crude halide with aqueous NaOH?

In a substitution reaction, the halogen atom is replaced by an -OH group to give an alcohol. For example: Or, as an ionic equation: In the example, 2-bromopropane is converted into propan-2-ol. The halogenoalkane is heated under reflux with a solution of sodium or potassium hydroxide. Heating under reflux means heating with a condenser placed ...
