The objectives in this laboratory were to explore the titrations of several known acids and bases as well as observing the mole reactions of the chemical reactions that each compound undertook. The four following acids and bases were used to predict when a set amount of reactant would reach equilibrium: Hydrochloric Acid (HCl), H2SO4 (Sulfuric Acid), NaOH (Sodium Hydroxide), and Ba(OH)2 (Barium hydroxide). An unbalanced equation of each reaction was given so the balanced equation was then able to be calculated. These are as follows including the theoretical ratio between the acid and base:
HCl + NaOH → H2O + NaCl 1:1
H2SO4 + 2NaOH → 2H2O + Na2SO4 1:2
H2SO4 + Ba(OH)2 → 2H2O +BaSO4 1:2
2HCl + Ba(OH)2 → 2H2O +BaCl2 1:1…
• To investigate the effects of on the rate of reaction of magnesium with different concentrations of Hydrochloric acid (HCl).
• To investigate the effects of different surface areas of magnesium in its rate of reaction with hydrochloric acid (HCl).
The rate in which reactions occur between chemicals, such as Magnesium and Hydrochloric Acid, are effected by four main factors. These factors are temperature, concentration, the presence of a catalyst and the surface area of…
of approximately 0.25 M Hydrochloric Acid
The aim of the study was to standardise a solution of hydrochloric acid with an approximate concentration of 2.5 M against sodium carbonate solution. The main steps of this experiment were preparing the sodium carbonate solution, transferring the solution into a conical flask by using a pipette, adding the bromophenol blue indicator and titrating with hydrochloric acid until the first green colour appeared. The concentration of hydrochloric acid…
The life of hydrochloric acid in our stomach
Chapter 14 section 1
Ms. Sara Kassem
Sharjah American International School
Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produced.
Hydrochloric acid (HCl) is a clear, liquid. Which is produced in…
Bradford for protein determination was used in the lab in order to determine the concentration of the unknown 2 and the previously purified protein. This protein dye complex is the reason for a shift in the dye absorption with maximum between 465 to 596 nm. This derived amount of absorption does not require dilution and can be used for both microassays and standard solutions. The analysis provides a linear response with concentrations of Bovine Serum Albumin (BSA) from 1 to 140 microliters. The…
Hydrochloric acid is a clear is a highly corrosive, strong mineral acid with many industrial uses.
Major production started in the Industrial Revolution, hydrochloric acid is used in the chemical industry as a chemical reagent in the large-scale production of PVC plastic, and MDI/TDI for polyurethane. It has numerous smaller-scale applications, including household cleaning, production of gelatine and other food additives, descaling, and leather processing. About 20 million tonnes of…
temperature affects the rate of reaction between hypo and dilute hydrochloric acid?
How does temperature affect the rate of reaction between hypo and dilute hydrochloric acid?
The kinetic particle theory explains the properties of different states of matter. The particles in solids, liquids or gases have different amounts of energy. As they are arranged differently and move in different ways. Solids vibrate on the spot and also are close together and are formed in a regular pattern. Liquids…
How does the increase of concentrated hydrochloric acid affect the rate of the chemical reaction with sodium thiosulphate?
Background to the Research question
Chemical reaction involves the chemical change of atoms and molecules, it will occur when two or more molecules interact with each other and the molecule will change. Thus, bonds between atoms are broken down and then new molecules are formed.
Hydrochloric Acid and Sodium thiosulfate are both colourless and clear…
In this experiment, two cations in an unknown solution were found using qualitative analysis. For Part A, the solution was to contain either silver or lead, while in Part B, the solution that was set on the side form Part A was identified to contain either calcium or barium. Part C explored a different method through the use of cation flame tests to observe colored flames from six metal chloride solutions.
In Part A, the initial step was to add HCl to the unknown sample. This was necessary…
and produce different products including copper (II) chloride and sodium sulfate (Na2SO4). The two above reactions require certain industry equipment and should not be done in a lab that is why those synthesis methods are completed in the industrial area. But there are other reactions that can be done in a laboratory setting. The next method is used most of the time because it is likely the easiest way in the laboratory to produce CuCl2. It begins with copper (II) oxide (CuO) and two…
