Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

Fact: Everyone has heard at least one Salt-N-Pepa song. Now‚ hear me out‚ I know you recognize these lyrics: “Let’s talk about sex‚ baby/let’s talk about you and me/let’s talk about all the good things/and the bad things that may be.” That song is appropriately titled “Let’s Talk About Sex‚” and it is a ballad about safe sex and sexual awareness as a whole.

learned about how salt affects the freezing point of water. In my science project I wanted to see if salt affected the freezing point of water. I started by doing some experiments. My first experiment was whether tap water or salt water would freeze first. I first started by mixing up the salt water warming it for one minute and warming the tap for one minute also. My second experiment was what ice cube would melt fastest. I started by getting two bowls. Two ice cubes‚ and salt. I began by sprinkling

Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

Socrates proposes a “myth of the metals” the ideal city’s citizens must acknowledge. These citizens accept their respective positions so as to maintain the social and political order‚ or‚ as Socrates articulates‚ to prevent revolution (422a). The “myth of the metals”‚ or the “noble lie”‚ emphasizes the importance of each individual fulfilling a specific function‚ which allows them to practice what Socrates and his peers have defined as justice (346d). Socrates propositions this “necessary falsehood”
