3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industria strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume o vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below.

How was Thin Layer Chromatography (TLC) used in organic synthesis reactions ? TLC is used to find the exact concentration of a catalyst in the reaction. TLC can speed up a reaction because silica gel is polar. TLC can separate components of a reaction mixture such as starting materials and products allowing the experimenter to identify what compounds are in the reaction mixture. TLC is used to find percentage yield of the reaction.

essayref Question Completion Status: QUESTION 3 Look at the Table of Reaction Mixtures at Room Temperature in the Lab Manual. Why do those solutions contain KNO3 and (NH4)2SO4? This is a case where reading the lab thoroughly could be most helpful. They are used in an effort to maintain the ionic strength of the solutions. The presence of these compounds is important to ensure the starch will turn blue-black in the presence of the iodine. The addition of those components speeds the reaction so that we can acquire the data in one two-hour lab period. The peroxydisulfate ion is unstable if the KNO3 and (NH4)2SO4 are not present. QUESTION 4 An important part of being able to do this experiment is the ability to handle dilution calculations. If a solution of concentration M1 and volume V1 is diluted to a new volume V2, the new molarity may be found by: M1V1=M2V2 Notice in this experiment that you are putting several components together to make your starting concentrations and it is…

QUESTION 1 Why do most living organisms have an enzyme decompose hydrogen peroxide? O Because often hydrogen peroxide is inhaled along with other gases in the air. O Because hydrogen peroxide is produced in the stomach and needs to be decomposed later. O Because hydrogen peroxide is too heavy to be helpful in most organisms. O Because hydrogen peroxide is a byproduct of metabolism.
