Title: To what extent does strong and weak acids differ in affecting the course of titrations. Introduction: The real life application that comes from this experiment links to agriculture. In the past decade, industrial dumping has become a controversial topic. Dumping hazardous wastes into river, ocean, and soil has resulted in a dramatic change in pH of the non-renewable resources and leads to a destruction in the ecosystem. Specially in agriculture, crops cannot grow in acidic soil, so it is…

triprotic acid, with different volumes of sodium hydroxide. Introduction When looking at the coefficient of balanced equations, stoichiometry is seen. Coefficients represent the number of moles, equivalent to the mass of an atom, of the products and reactants. Stoichiometry was demonstrated in this experiment to determine the relationship between the testing agents. A polyprotic acid or base is used because it is able to react with varying molar equivalents of sodium hydroxide. In…

Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…

What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

ANALYTICAL METHODS Determination of λ max Gemifloxacin mesylate λ max is determined by preparing one standard concentration of 10μg/ml and scanning should be done. Preparation of 0.1N HCL 8 ml of hydrochloric acid is taken in 1000ml volumetric flask and dissolved with distilled water and then make up to 1000ml with distilled water. Standard graph of Gemifloxacin mesylate: The λmax of Gemifloxacin mesylate in 0.1N HCL was scanned in UV-Visible Spectrophotometer and found to have maximum…

Chemistry plays a vital role in everyday life even though it may not seem like it. One of these things include firearms, which exhibits chemistry throughout the whole entire process. They show chemical and physical properties ranging from the gunpowder to the actual process of firing a bullet. Gunpowder is what makes the whole reaction occur. Without the use of chemistry throughout a firearm, would make it useless and it wouldn't work. These uses of chemistry occurs so fast that you may not…

How To Pass A Hair Follicle Drug Test Used by employers, corporations, law enforcers, and even parents, hair drug testing is one of the growing methods for drug testing. With it, someone can be tested for drug use as far as 90 to 120 days ago. And unlike urinalysis, there’s no way to adulterate or dilute the hair samples to mislead the results. Now, you might be worried and asking: “How do I pass a hair drug test test!?” First off, know that this isn’t a fool-proof method, but many have had…

concentration of the sodium hydroxide solution in part one of the experiment. It was known that the potassium hydrogen phthalate and sodium hydroxide should have had a 1:1 stoichiometric molar ratio. Potassium hydrogen phthalate was used as the primary standard because it is a very pure concentrated substance that can be predicted. However, the sodium hydroxide is too difficult to be measured because of its tendency to absorb water vapor. This is one area where error can be noted; at times the…
