Acetyl chloride‚ CH3COCl‚ also known as ethanoyl chloride or acyl chloride‚ is an acid chloride derived from acetic acid. It belongs to the class of organic compounds called acyl halides. It is a colorless liquid. Acetyl chloride does not exist in nature‚ because contact with water would hydrolyze it into acetic acid and hydrogen chloride. In fact‚ if handled in open air it gives off white smoke owing to the hydrolysis from the moisture in the air. The "smoke" is actually small droplets of hydrochloric

Signed_________________________________________ Abstract A common road salt‚ magnesium chloride‚ was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a deicer. To determine the Van’t Hoff factor‚ the difference of temperatures of freezing water and a solution of magnesium chloride was determined. A Van’t Hoff factor average of 2.88 was found‚ which

An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve sodium chloride. Sodium chloride is an ionic compound. 4. Some drinks like tea are consumed hot or cold‚ whereas others like Coca-Cola are consumed only cold. Why? For taste reasons‚ these drinks can be drunk if the user likes It but having coca cola like tea would

In the experiment‚ we tested a sodium chloride solution. Along with the tested solution‚ control groups (water and sodium phosphate) were used to be help understand whether or not NaCl was a buffer. Water was the negative control group and sodium phosphate was the positive control group. If NaCl was a buffer than the pH would be stabled as the sodium phosphate buffer. If NaCl was not a buffer than the pH would fluctuate like the negative control‚ water. During the first trial and prior to the drops

Making Sodium Chloride Equipment: Method: 1. Firstly‚ safety measures were taken by putting on laboratory coats‚ wearing safety goggles and tying long hair back. This was to protect clothing‚ eyes and to avoid burning as the experiment included dealing with open flames. 2. The equipment needed (as shown and labelled in picture A) was collected. 3. Using a measuring cylinder for each‚ to be exact with measurements‚ we measured out 10cm³ of HCl and 10cm³

Title: Prep of t-Butyl Chloride via SN1 Reaction Purpose: The purpose of this experiment is to synthesize tert-butyl chloride via an SN1 reaction. t-Butyl Chloride was synthesized from t-Butyl Alcohol using hydrochloric acid in separatory funnel; isolation of t-Butyl Chloride was done under distillation conditions. The experiment resulted in 8.29grams of purified compound‚ which is a 66.27 percent yield. Procedure: As per handout with changes Equation: Mechanism: Results: (Scan

energy lost by Calcium Chloride and gained by Ammonium Nitrate when dissolved in Water. Theory: Exothermic reactions are when net energy is lost in process of reaction. When solid calcium chloride (chemical formula CaCl₂) is placed in water‚ the calcium chloride dissolves and liberates heat in the process. Calcium chloride is one of the ingredients in instant "hot packs" sold in retail stores. Some concrete mixes incorporate calcium chloride to decrease drying time. Calcium chloride is also used as a

The halides in unknown solution were identified as iodide and chloride based on their experimental E°(Ag/AgX) values‚ -0.16 ±0.01V and 0.22 ±0.02V respectively. These results were both accurate with percent error of 5.96% for iodine and 0.9% for chloride. The literature value of E°(Ag/AgI) and E°(Ag/AgCl) were -0.151V and 0.222V respectively (1). In addition‚ the literature vales lay within the 95% confidence interval for both halides therefore the results were accurate. These results were precise
