This is for my biodiesel lab- This is a biodiesel synthesis... we are using vegetable oil in a trans-esterification reaction. 100%pure vegetable oil + CH3OH --> biodiesel (NaOH) is above the reaction arrow. We stir 2mL of methoxide solution in a beaker for 20 minutes. The reaction has CH3OH as reactant and NaOH as condition (written on the top of the arrow). This step uses sodium methoxide. WHAT IS THE RELATIONSHIP? Also, for glycerol and methyl ester (biodiesel)- WHAT PROPERTIES...

Suppose you add a solution of calcium hydroxide to a solution of sodium carbonate and a precipitate forms. You measure the total amount of the precipitate (in g) as a function of time. At time 0, 20.0 s, 40.0 s and 60.0 s you get a cumulative weight of 0.00 g, 4.82 g, 6.33 g and 8.49 g of the precipitate, respectively. What is the average rate of reaction between 40 and 60 seconds in mol/s? Enter a numerical value...

sodium bicarbonate 10 g sodium carbonate 12.72 g, add-50 ml of deionized water to the beaker and stir until all of the weak acid or weak base has dissolved. Carefully and slowly pour the weak acid or weak base solution into the volumetric flask. preparation of Buffer pour your weak acid and your weak base together into a bottle. How many grams of sodium bicarbonate (M.W.= 84.01 g/mole) would you have had to weigh out to make up 500ml of...

Post-‐Lab to Accompany the Grignard Synthesis of Triphenylmethanol You were instructed to add the bromobenzene in increments during the Grignard preparation to prevent an unwanted side reaction. What would the product of that reaction be (show structure also)? How was it removed during work-‐up from the triphenylmethanol product?

These questions are based on the Synthesis of Methyl Orange lab using p-Sulfobenzeneazo-4-dimethylaniline sodium salt. 1. What is the need of adding NaOH during coupling reaction (here)? Write necessary equation. 2. Based on pKa of MO (3 4), what will be the color of MO in regular water? 3. Identify active electrophile(s) and nucleophile(s) during coupling reaction with necessary structures.

LAB Discussion: Why is it important to add a solevent to a solid during recrystalization and not the other way around? Why is the melting point of a mixture of two different compounds lower and broader than the melting point of a pure compound? Why would a percent recovery be lower when measuring the weight of the recrystalized over the impure ratio? I got 73 perecent recovery

In the caffeine extraction from an energy drink lab: a. Why was it necessary to extract the caffeine from the energy drink? Why could we not have sublimated the energy drink directly as a solution? b. Why did we extract the energy drink with dichloromethane, specifically, and not another organic solvent such as methanol or hexane?
