Lab Report For Ph Solutions

Aspen Wilson Lab Report: pH Solutions September 26, 2014 Introduction: In this lab we measured pH using a variety of methods and materials. After the solutions we tested them with an indicator. By using the indicator we developed a concept of how each solution differed in relation to the pH scale. Material/Methods: Water: We used indicator paper to determine its pH. When tested by placing the indicator paper in the water, we found out that water has a neutral pH because it turned the indicator…

Standardizing A Solution Of Sodium Hydroxide

Standardizing a Solution of Sodium Hydroxide PURPOSE: To determine the concentration of sodium hydroxide. OBJECTIVES: ● ∙ Prepare an aqueous solution of sodium hydroxide to a target molar concentration. ● ∙ Determine the concentration of your NaOH solution by titrating it with a solution of potassium hydrogen phthalate, abbreviated KHP, of precise molar concentration. MATERIALS: LabPro or CBL 2 interface solid sodium hydroxide computer or handheld…

Titration Of Sodium Hydroxide Solution

of the Sodium Hydroxide? Hypothesis: A large volume of Oxalic acid will neutralise 20ml of Sodium Hydroxide. Dependant Variable: Concentration of 20ml Sodium Hydroxide solution. C_NaOH=n/V Therefore, [NaOH] is directly proportional to it number of moles, and inversely proportional to its volume. Independent Variable: Average volume of Oxalic Acid solution titrated against the 20ml Sodium Hydroxide solution. Controlled Variables: The volume of Sodium Hydroxide solution; only 20ml of Sodium Hydroxide…

How To Neutralise Aspirin

The coated aspirin took less drops of sodium hydroxide than the uncoated aspirin because to neutralize an acid you need a base and the coated aspirin was covered in a base compound that partially neutralize the acidity of the acetylsalicylic acid making it not need as many drops of sodium hydroxide. For someone who must take Aspirin on a regular basis the acid-reduced Aspirin is a better choice because regular Aspirin is more acidic than the acid-reduced Aspirin and can cause painful ulcers. The…

Irresistible Lab Report Chem 109 Essay

Abstract A buffer is a solution that resists changes in pH when H+, OH-, or H20 is added. By using standard lab equipment, a lab pro diagnostic tool, and acidic and basic solutions, the pH can be found. By recording the pH while adding a base or an acid gradually to a buffer solution you can find the capacity of each buffer to resist drastic changes in pH. The best buffers will keep a solution from becoming either too acidic or basic with the addition of a strong base or acid. Introduction The…

they are strong acids and alkalis). You use it to figure out how many moles you have in an acid or alkali, you need to know how many moles there are in the other for this to be of any use. You add the acid into the alkali using the burette until the pH is 7 this is when the titration normally ends if you are using acids and alkalis of equal strength. The endpoint of the titration is reached when there is an equal concentration of the titrant and the solution of unknown concentration. How is this…

test. In this test, we will be burning the unknown substance to get a color in the flame. Some of the colors that could be emitted are red, orange, or it can also be colorless. We finalize that by using the flame test, solubility test, and finding the pH to give us the factors to match with an element or compound.…

Pectin Lab Report

In this investigation pectin was modified using pH and heat. Initially the low methoxyl citrus pectin was dissolved in water at a ratio of 1.5g in 100ml. As the modification process was carried out three times, I began by dissolving 4.5g of low methoxyl pectin in 300ml of MilliQ deionised water in a laboratory glass bottle over a magnetic stirrer. The first step in modifying pectin is to increase its pH using 3N sodium hydroxide. This quantity would ensure there is enough modified pectin for further…

Osmosis: Acid and Ph Essay

Common Foods and the pH Scale Background: Acids and Bases The Bronsted-Lowry definition of acids is that acids are compounds that give off H+ ions when they react with another compound. Likewise, this definition says that bases are compounds that accept H+ ions from other compounds. The Arrhenius definition of acids says that they’re compounds that give off H+ ions in water and that bases are compounds that give off OH- ions in water. These definitions are the same. Basically…
