Chromotography Study guides, Class notes & Summaries

This is my Unit 2 assignment, it contains part D of assignment unit 2 Practical Scientific Procedures and Techniques of BTEC applied science. i gained a DISTINCTION for this assignment, the assignment includes: Self-evaluation of each of the required practicals that i undertook, these include: Titration, Colorimetry, Calorimetry, Chromotography, for the self evaluation i had to evauluate my skills on how i went about the practical,also including any improvements that would have further improved...

volumetric flask - ANSWER used to accurately prepare solutions of various concentrations often used in titrations erlenmeyer flask - ANSWER can be used for mixing, transporting, and reacting, but are not appropriate for accurate measurements repippette - ANSWER hand operated pump that dispenses solutions beakers - ANSWER can be used to measure mass or dissolve a solvent into a soulte graduated cylinder - ANSWER used for precise measurements and are more accurate than erlenmeyer fl...

Experiment for Diffusion? - Correct Answer 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? - Correct Answer 1) Put a coloured substance in a solvent e.g food colouring in water. 2) Over the time, the colour levels out but is weaker than the origi...

What are the 5 steps in the Scientific Method? - ANSWER 1. Identify a problem or pose a question based on an observation. 2. Formulate a hypotheses. 3. Conduct experiments or tests the hypotheses. 4. Observe and record the results. 5. Draw a conclusion (was the hypothesis correct?). * peer review is also important. Metric Unit deca (da): - ANSWER x 10^1 Metric Unit hecto (h): - ANSWER x 10^2 Metric Unit kilo (k): - ANSWER x 10^3 Metric Unit mega (M): - ANSWER x 10^6 Metric ...
