Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held

commonly defined as a serum sodium concentration ≤135 meq/L [2]. An overview of the causes of hyponatremia will be presented here (table 1). Most of the individual disorders are discussed in detail separately‚ as are issues related to diagnosis and treatment [1‚3]. (See "Diagnosis of hyponatremia" and "Overview of the treatment of hyponatremia".) It should also be emphasized that‚ in selected patients‚ multiple factors may contribute to the fall in the plasma sodium concentration. Symptomatic

We also looked for precipitants that were formed from the mixing of the different substances. We used barium nitrate‚ potassium hydroxide‚ sodium sulfate‚ magnesium nitrate‚ aluminum sulfate‚ and iron (III) chloride in set one. In set two we used potassium chloride‚ sodium hydroxide‚ magnesium nitrate‚ barium chloride‚ sodium sulfate‚ and magnesium sulfate. For each set‚ we mixed two drops of one compound in five wells of a spot plate. We then added two drops of all the other substances to the compound

aqueous solutions of calcium chloride and sodium carbonate. These solutions will be prepared from 2.01 g of calcium chloride and 1.06 g of sodium carbonate . Materials: 3 beakers 100 mL graduated cylinder rubber policeman funnel filter paper Procedure: 1. Put on your safety goggles. 2. Obtain two clean beakers. Rinse the inside of the beakers with a small amount of distilled water. 3. Obtain the correct amounts of calcium chloride and sodium carbonate. Enter these masses in your

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

Experiment 4: To recover cyclohexanone from the oxidation of cyclohexanol by hypochlorite Experiment 6: To recover adipic acid from the oxidation of cyclohexanone CHEMICAL REAGENTS Cyclohexanol Acetic Acid Chlorine (Bleach) Thymol Blue (indicator) Sodium Hydroxide These reagents were all used during experiment 4. APPARATUS USED Simple distillation apparatus 250mL round bottomed flask PROCEDURE: Experiment 4 8 mL of cyclohexanol was placed into a 250 mL Erlenmeyer flask‚ and then a thermometer

Experiment: Reaction of distilled water and solid sodium hydroxide RESEARCH QUESTION How does the heat released during the reaction between distilled water and Group 1 elements (lithium‚ sodium and potassium) vary as one goes down the group? OBJECTIVE The objective of the experiment is to measure the heat change during the reactions with minimal heat loss to the surroundings. MATERIALS The materials to be used in this experiment are: • Lithium‚ sodium‚ and potassium metal are the three Group 1 elements
