Hydrogen chloride

If the substance clumps at the bottom, continue to stir until the mixture is dissolved completely. Take a clean volumetric pipette and set up five test tubes. Using the pipette, portion out 0.1 ml of the unknown solution and place it into each test tube. This will evenly divide the solutions for testing. pH Test Fig. 1 The purpose of the ph test is to determine whether the solution is acidic or basic. Next, taking a ph strip, dip the end of the strip into the solution to gauge the ph. Record your result. Based on this finding, you can begin to narrow down the list of possible solutions. Silver Nitrate Test Fig 2. Silver Nitrate is used to determine if the Chloride Ion, Cl-, is present in the solution. If the Chloride Ion is soluble, when Silver Nitrate is added, a white precipitate of silver chloride soluble in diluted ammonia will be produced (4). Taking a test tube, add 0.1 mL of silver nitrate to the solution and mix the mixture together.Record your result. Sodium Hydroxide Fig 3. Sodium Hydroxide will determine the presence of NH+. If a blue color shows on the litmus paper, the solution is positive for NH+ (5). Taking a second test tube, add 0.1 mL of Sodium Hydroxide to the solution. Mix well. Once the mixture is mixed thoroughly, take one strip of litmus paper and add it to the solution. this should present a blue color. If a blue color is present, NH+ is present in the solution. If litmus paper is not present, a regular ph strip will work, however, the…

Introduction The reaction of Hydro Chloric Acid with Aluminum is exothermic and very dynamic. The Hydrogen produced at such temperatures can easily explode by combining with the oxygen of the atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl =…

a scale of 7, by the data from Data table #2, the white liquid that contains Magnesium, Chlorine and Hydrogen start to release fumes. As time passed, the liquid start bubble, and the liquid start to become…

As it can be seen the concentration of the phenol compounds decreased as the hydrogen peroxide increases. The presence of the anions decreases the rates of the phenolic compounds, the sulfates influence in a smaller degree. For phenol and 2-nitrophenol the difference in slope or degradation rates for chloride and sulfate are 0.71 and 0.55, and only 0.16 for 2-chlorophenol. The presence of chloride inhibits in greater proportion the formation of hydroxyl radicals than the sulfate , this can be…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

Chlorine is the second to lightest member of the halogen elements. It is in Group 17 (Group VIIA) and period 3 of the periodic table. The element symbol for Chlorine is Cl. Chlorine is a greenish yellow gas that is corrosive, toxic and can be irritating to the eyes and respiratory system. Chlorine is a nonmetal that has the atomic mass of 35.45 amu. It has a melting point of -100.98 degrees Celsius and a boing point of -34.6 degrees Celsius. However, at room temperature it is a gas. Chlorine…

This experiment analyzed the dissolved ions in a certain sample of seawater that was collected all around Galveston Bay and allowed an understanding of the composition of saltwater. The students were separated into four groups, each received a sample of seawater from a different location, such as Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded…

Based on our observations from the Zinc and Hydrochloric Acid Lab, we concluded that the chemical reaction that occurred was exothermic and a single displacement reaction. The experiment consisted of zinc (Zn) and hydrochloric acid (HCl) being mixed in a test tube immersed in water. First of all, bubbles were produced during the reaction. Also, a white powdery substance was produced with properties different from those of any reactant. The bubbles suggest that the reaction was a chemical…

In the first step of the experiment, m-toluic acid reacted with thionyl chloride to form the acid chloride derivative of m-toluic acid. In this reaction, the carboxylic acid is first converted into an acyl chlorosulfite intermediate, replacing the –OH of the acid with a better leaving group. The acyl chlorosulfite then reacts with a nucleophilic chloride ion, at which point the chlorosulfite leaves in the form of sulfur dioxide and chloride ion. The remaining acid chloride then reacts with…

when put in water, as it produces hydrogen gas and alkaline solution (alkali metal hydroxide). The alkali metals reacts very fast and violent with water, as when you place the metals (lithium, sodium or potassium)…
