Hydrochloric acid

all the different types of reactions because they often refer the reactions as being of one type or another. The first reaction is Acid-base (Neutralization) Reaction. A neutralization reaction occurs when an acid and base are mixed together. The compound formed by the cation of the base and the anion of the acid is called a salt. The combination of hydrochloric acid and sodium hydroxide produces common table salt. An example is…

ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

the other three liquids. It was expected that whichever combination of liquid and black solid formed a blue solution would be H2SO4 and CuO hence, CuSO4 in solution. On identification of sulphuric acid, the following tests were performed expecting the evolution of carbon dioxide on reaction of the acid with carbonates. Therefore, among the soluble solids, (10) exhibited effervescence and was suspected to be sodium carbonate due to its solubility. The powders and crystals were divided…

constant variable is the acid which is in the flask. When the solid acid dissolves to form ions, 1 mole of H+ ions are produced for every mole of acid being used. Molarity is used to calculate moles per liter of solution. The most dangerous part of this lab is the risk of getting…

either acid or base. Note: This activity may take more than one lessons. On the first lesson, students group, discuss and prepare their experiment. On the second lesson, students will have opportunities to carry out the investigation, then record, process, and evaluate their data. Preparing materials In the original experiment, hydrochloric acid and sodium hydroxide solutions have been used as acidic and basic solution, respectively. However, year 9 students might know that hydrochloric acid…

Also, we used acidic indicator phenolphthalein to determine the end point of experiment when the color turns from colorless into red or pink. Potassium acid phthalate is our primary standard and this huge molecule has molecular mass equal to 204.2 g/mol. (KHC_8 H_4 O_4 ) and it has abbreviation as KHP. Also KHP is monoprotic and will react in a simple one to one ratio: NaOH(aq) + KHC_8 H_4 O_4 (aq) →KNaC_8…

Introduction: Kidney stones are an extremely basic urinary issue. Also known as renal calculi, kidney stones are characterized by their high occurrence and a high repeat rate. This issue results from the arrangement of insoluble salt stores in the urinary tract and inside the kidney. The rate of this issue has expanded in the course of recent years for reasons that are not entirely known, but have caught the consideration of numerous scientists. There are different types of kidney stones, each…

Conclusion The empirical formula of the copper chloride hydrate compound is CuCl2 · 2H2O. Discussion of Theory The technique of gravimetric analysis can be used to find the empirical formula of a compound when the amount of it is known. By dehydrating the copper chloride hydrate sample and using it for an elemental copper-producing chemical reaction, one can isolate the masses of the water, copper, and chloride and determine their mole ratios. Since the Law of Definite Proportions states that a…

indigestion or symptoms of acid reflux. There are many types of antacids such as calcium, aluminum and magnesium. They’re many ways to consume antacids such as liquids, tablets and chewable tablets. The experiment will be tested with three different antacids which are: bismuth ($5.99) (picture 1&4), life brand milk of magnesia ($8.99) (picture 2&3) and Gaviscon ($11.99) (picture 5). Purpose The purpose of this experiment was to figure out the best brand of antacid…

alcohol while eating, or eating greasy, fried or spicy foods. Acid in the stomach helps digest food and prevents infection. Mucus lines the stomach, bowel and oesophagus and acts as a barrier against the acid. If the layer of mucous gets damaged, the stomach acid can aggravate and cause inflammation to the stomach; this leads to indigestion or heartburn. Antacids are medicines that can relieve symptoms of indigestion by neutralising the acid in the stomach. They are made up of bases and…
