Hydrochloric acid

physical properties of the elements that are interacting. As of the experiment, when the copper wire and copper (II) sulfate were put together, no physical change was observed. Moreover, copper is not an active metal and does not react with diluted acids. This leads to the conclusion that no reaction occurred between them.…

Hiking Hydration Packs Keeping yourself hydrated is a must while hiking, but toting around disposable water bottles in your backpack and trying to drink from them while walking can be a real juggling act. That’s why more and more hikers are strapping on hydration packs before trekking the backcountry. A top-quality hydration pack make carrying up to 3 liters of water on your surprisingly easy, and you can take sips from the shoulder-high tubing system as often as like without breaking your…

people take to help with an imbalance of the pH of their stomach acid because it neutralizes the gastric acid present (Antacids | Drugs.com). Although the is not just one brand of antacid that is available to people, and most people want to take the best antacid that will help with their acid imbalance. In our lab, we were given the question of which antacid out of the antacids provided to us was the “best” at neutralizing stomach acid. To answer that question me must first establish what makes…

The number of moles of hydrochloric acid neutralizes for the three trials (2,4,5) were calculated using stoichiometry. It was calculated for trial 2 by convert 4.88 mL NaOH to L by divide by 1000 mL. Then, to get to mol of NaOH the molarity of NaOH was multiplied by 0.00488. Then to get from NaOH to HCl, the mole ratio 2 HCl to 1 mol NaOH was multiplied by 0.00122. To get the amount of HCl per beaker, 100 mL of HCl was divided by 1000 mL to get 0.1 L. Then, the liters were converted to moles by…

on it which would have been removed with the stick. It is less clear why the benzoic acid was overproduced. Some of the organic layer may have been drawn off with it, but the vacuum filtration should have left only the benzoic acid. There could have been an error in weighing the filter paper before the procedure. There also could have been contaminants in the basic extract, causing more than just the benzoic acid to be filtrated. There is also the chance that too much starting material was…

This paper describes the process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end…

Antacids are essential in science and everyday life. They work to neutralize an acid in a reaction. Antacids are bases and the chemistry definitions of a base vary. A base is defined as a substance that produces OH- ions in solution in the Arrhenius definition. There is also the Bronsted Lowry definition and the Lewis definition. They are defined as the following respectively: a proton acceptor or H+ ion acceptor and an electron pair donor. These terms are used interchangeably to figure out if…

First, have a wire loop for the flame test and adjust the burner so it is blue and no-luminous. Then, clean the wear loop by dipping it in concentrated hydrochloric acid and heat the flame until it glows. Pour about 10 milliliters of 10% sodium chloride solutions into a small beaker and for unknown use 2mL of unknown solution instead of sodium chloride. Dip the clean wire loop into sodium chloride solution and…

and [HI] will decrease. 4. 20 grams of magnesium were placed in a conical flask. Which one of the following solutions, if added, would produce 100 mL of hydrogen gas the fastest? A. 100 mL of 4 M sulfuric acid B. 200 mL of 2 M sulfuric acid C. 400 mL of 1 M sulfuric acid D. 50 mL of 8 M sulfuric acid 5. Why does the rate of reaction increase when powdered calcium carbonate is used instead of marble chips? A. The powdered calcium carbonate acts as a catalyst. B. There is an increase of the…

experiment was to determine the percent by mass of acetic acid within a sample of vinegar using volumetric analysis with the titration technique. The theory is that if the volume and molar concentration of the standardized sodium hydroxide (NaOH) solution is known, then the percent by mass of the acetic acid (CH3COOH) in vinegar can be calculated after a titration.1 Within this experiment, a NaOH solution was standardized with a primary standard acid of potassium hydrogen phthalate (KHC8H4O4) in…
