given Solution using Titration Morphy Kuffour Mrs. Langlis‚ AP Chemistry C-D 9/24/2017 Purpose: Determining the precise concentration of vinegar through titration using a standard solution of Potassium Hydroxide (KOH) (aq) Background: Vinegar is a solution of acetic acid (CH3COOH) in water. The concentration of acetic acid in Vinegar is written as a Molarity (mol/L). In this experiment‚ titration is used to determine the concentration of acetic acid in vinegar. Titration is an experimental technique

Qualitative vs Quantitative analysis Qualitative analysis: Richness and Precision The aim of qualitative analysis is a complete‚ detailed description. No attempt is made to assign frequencies to the linguistic features which are identified in the data‚ and rare phenomena receives (or should receive) the same amount of attention as more frequent phenomena. Qualitative analysis allows for fine distinctions to be drawn because it is not necessary to shoehorn the data into a finite number of classifications

Soft drinks‚ also called as sodas‚ are one of the most popular beverages that are drunk worldwide. Several brands of sodas‚ mainly from the brands The Coca-Cola Company‚ Pepsi‚ and Dr. Pepper-Snapple‚ are competing in their sales. As of 2012‚ the leading brand of food beverages is Coca-Cola. Statistics show that more than a billion Coca-Cola products are consumed daily worldwide. That means that we are consuming more sodas than ever before‚ and many health issues are showing up‚ including teeth problems

Soda Tax: The Beginning of the End The government plans to tax sugary drinks to lower consumption and reduce obesity rates. It is a tax that is justified‚ because a high majority of its consumers are obese and our government believes they should step in and do something about it. There are positive aspects of a soda tax‚ but it would also be a violation of freedom of choice‚ with many other red flags as well. The government simply‚ has too much involvement with our personal lives. Placing a

Vinegar Titration Lab Procedure: 1.) Obtain ~100 mL of NaOH. Record the molarity on the data table. 2.) Set up a ring stand with a buret. 3.) Place 5mL of vinegar in a 125 mL Erlenmeyer flask. Dilute the vinegar with 25 mL of water and add two drops of phenolphthalein. 4.) Fill the buret with NaOH. Record the initial volume of the buret in your data table. 5.) Titrate the vinegar sample until the first faint pink color does not disappear. 6.) Record the final volume of the buret in your data

Soda Consumption There are many studies today that show a link between obesity and regular soda consumption. Our study is about how regular pop consumption is more popular with young‚ nonwhite‚ low-income Americans. “Half of Americans aged 18 to 29 say they drink regular soda‚ making them the most likely to do so across not only age groups‚ but also across all major demographic and socioeconomic groups.” (galloppoll.com) Two groups known in America most likely to be obese according to studies

The acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration

Question 1: What is the difference between a leading performance indicator and a lagging performance indicator? Why is each type important? Leading indicators are activities that should be trended as they predict the outcomes (i.e.‚ lagging indicators). Quotas or goals should only be placed on lagging indicators and never on leading indicators. Placing a goal on a leading indicator will result in gaming and generate the wrong results. Advantages: Predictive in nature and allows the organization
