determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong base‚ sodium hydroxide (NaOH). In order to do so‚ we prepared NaOH solution‚ prepared a buret‚ and standardized this solution by performing a colorimetric titration of the KHP with the solution until a color change was present. The color change was introduced

The most chivalrous knight that I know of is William Thatcher. Over the past few weeks I have learned about what it takes to be a chivalrous man. There’re more than a couple quick reasons on why the peasant boy William Thatcher is the most chivalrous knight that I know. For one reason‚ William is protecting the weak. He puts his life on the line so that his fellow peasants and him eat and are well clothed. William pretends to be a Nobel man‚ which is lying about his real ideality‚ but

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor. Any

I never had much of an interest in my safety classes and solely chose the major based off good things people had told me. After college I would like to work in an elementary school; currently I think I would like to teach any grade from first through third. I believe ageism can be prevalent in the teaching profession

Base Details In the poem‚ “Base Details‚” Siegfried Sassoon expresses his great disgust towards the majors in the military. He is disgusted and appalled at the way the majors act while men are dying out in the battlefield. Sassoon is angered by the fact that the majors are living a life of luxury while sending young men “up the line” out into the battlefield. The title of the poem suggests these ideas. “Base” indicates a military installation‚ but another meaning is morally low; and the word “details”

Good Wives‚ Laurel Thatcher Ulrich contends that unlike some historians would come to believe‚ Puritan women lived neither in a state of submissiveness or autonomy. Rather these women served as a complementary secondary function to the husband responsible for performing a variety of duties. In her “role analysis”‚ Ulrich structures her argument based three different characters from the Bible‚ a fitting organization due to the supremacy of the Church in early New English society. Her three prototypes
