Experiment #2 “Density Determinations” Report The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt‚ to see how density changes as a function of concentration.” In experiment #2‚ part II‚ calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased‚ so would the density‚ because adding weight would increase the density of each solution. The density calculations

Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

Task 1c – M3: Glucose Solution Concentration (%) Absorbance (Arbitrary Units) 1 1.61 0.1 0.32 0.01 0.23 0.001 0.22 How to use a Colorimeter: • A Colorimeter measures the absorbance of particular wavelengths of light by a specific solution. • Firstly to use the Colorimeter you must switch it on 5 minutes before use to allow it to stabilize. Next select the most appropriate filter for the analysis and then anter it into the light channel or the selector depending on the type of Colorimeter you

Voices rise in the caves. They get jumbled into the air‚ but can be heard from miles back. Inside‚ people are yelling and screaming at each other‚ throwing stuff and kicking. FIghts erupt and get out of hand‚ with guys punching‚ and girls pulling each other’s hair. Turmoil‚ mayhem‚ chaos have all broken out into the hot air of the island. Unknowingly‚ a thud of thunder rumbles in the distance. ~ Catherine Tears fall down my face as I run through the tunnels and out towards the night. I cannot

Right to self-determination All of us have the right to self-determination. In a far view‚ right of self-determination simply means that all people have the right to freely determine their political status and pursue their economic‚ social and cultural development. This merely involves the freedom to acquire and dispose of property and wealth generally as the person choses. Right to self-determination is an unalienable right; the government can’t take the right away. The specific right applies

My – Health 350 Week 3 DB – Energy Drinks Something I learned in my last Health class is the ever-increasing use of today’s new “Energy Drinks.” Caffeine is the single most used drug in America. How many of us must have that morning cup of coffee before heading out the door? How many college students are staying up late at night preparing for a mid-term or final exam by drink these new‚ all natural‚ safe‚ energy drinks? You may want to read their labels and adjust your thinking. You

Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

Sports Drinks and Homeostasis Gail B. Wortmann Iowa Learning Online 2001 Iowa Teacher of the Year Teacher Notes: Sports Drinks and Homeostasis Personal notes from the author: If you want students to have a rich discussion about a topic‚ the topic has to be “on their agenda.” Students need to have something from their past experience to contribute to make the discussion truly engaging. Most students have tried sports drinks at some time in their life‚ and therefore‚ have experiences
