Distillation is a technique that is to purify liquid compounds. Explain how distillation is used to separate the target product from any residual unreacted starting material. [2.0 Marks] Upon completion of the reaction (before filtration), an additional 4.0 mL of 1.0 M NaOH/EtOH was added to the reaction. What was the purpose of this step? Include a chemical reaction as part of your answer. [1 Mark] The term “side reactions” refers to any chemical reaction that can occur that form...

1. Discuss the applicatoin of distillation as a separation and purificatoin technique. Are there limits due to sample size, initial purity and final purity desired? 2. Discuss the applicatoin of gas chromatogrpahy as a separations and identification technique. Are there limits due to purity, sample size, phase of sample?

Steam distillation lab? One can prepare homemade lavender perfume by steam distillation,one of the main components in the lavender oil is linalyl acetare (MM 196 g/mol), which has a vapor pressure of 20 mm Hg at the boiling point of the mixture with water. If one collect 500 g of lavender from a garden and performs a codistillation with water, what would be the compositions of the distillate? This is all that was given??

The following diagram shows a distillation process. Distillation is a technique used in chemistry to purify water from dissolved impurities, mainly salts.

The following diagram shows a distillation process. Distillation is a technique used in chemistry to purify water from dissolved impurities, mainly salts. An example is the conversion of sea water to fresh water as is done in many countries including Oman. Temperature plays an important role in distillation process and the various steps involved are as follows. Step1: Heating impure water to produce steam in the distillation flask. Step2: Steam passes through to the Liebig condenser where it is condensed. Step3: Condensed water...

Q4: Distillation columns are the most commonly used technique for separation purpose in industries. The operating conditions such as temperature, pressure and flowrates are the main factors to ensure that proper separation is taking place inside the column. From your study of distillation column: A. Explain the effects of sudden change, increasing and decreasing of these factors in separation processes. B. Explain the relationship between partial pressure and vapor pressure.

As a reminder, PCR is the technique used to replicate DNA in the lab. PCR is based on the way DNA is replicated in cells. During PCR template DNA plus other ingredients are placed in a test tube and the solution goes through repeated cycles of heating and cooling. The 'ingredients' of a basic PCR reaction are: DNA template, primer, nucleotides, DNA polymerase, and any salts required for polymerase function (buffer). No ligase is required in PCR but it is...

Distillation post lab: 1-why was the temperature of the heater probe so much higher than the distillation temperature? 2-what is the same comparing separation by distillation to separation by TLC? 3-even if you heated the boiling flask until it was dry, not all the highest boiling compounds will be condensed and collected. why? 4-describe 2 ways in which the distillation set up could break and describe how to avoid that.
