Interpretation Introduction
Interpretation:
The flow diagram for the following points is to be drawn-
First point is that the solvent peak is separated from the two analyte which has the lower volatility in comparison of the solvent.
Second point is that the solvent peak should not reach to the analytical column.
Third point is that the analytes which are different in polarity should be separated and determined quantitatively.
Concept introduction:
The flow diagram is depicted as the representation of workflow which includes the step-by-step approach to solve the complete task or to fulfill the given requirements.

Briefly describe the principles for separating the components of a mixture by solvent extraction.
25 ml of pickled brine was taken from an apple pickled with vinegar and diluted to 500 ml, 25 ml of this was taken and acidity was determined with 0.2 N (Factor: 1.05) NaOH. In the main trials, 6.3 ml - 6.5 ml - 6.9 ml, respectively, 0.1 ml base was used in the analysis without using the sample.For example, how many ppm is its acidity?

- You find that for your analysis, your response factor (adjusted for internal standard) for a particular analyte was 0.0104 ppm. When you run a sample mixture, the integration for that component is 2,186, and the integration for the internal standard is 14,139. What is the concentration of the component in ppm? (Enter the numerical value without units.)arrow_forwardIntroductlon In Part (a) of this experiment you will prepare a primary standard. Potassium hydrogen phthalate (KHP) is a monoprotic acid with the formula KHC,H.O. In this experiment KHP is used as the primary standard. A standard solution is one whose solute concentration is accurately known. If a solute can be obtained in a very pure, stable, weighable form, a primary standard solution of it can be prepared directly. You will then use the standardized sodium hydroxide solution to determine the acetic acid content of a dilute unknown solution. Procedure (0) Preparation of a Primory Standard Potassium hydrogen phthalate (KHP) is a primary standard. Weigh accurately by difference, approximately 0.8 g of KHP in a clean, dry weighing bottle and transfer it into a 250 ml conical flask. Add 75 ml of distilled water. Swirl gently. Cover the flask and leave to dissolve, swirling periodicaly. Cautlon: KHP is not highly soluble and care must be taken to ensure it is all dissolved before you…arrow_forwardBriefly explain the principles involved in the separation of the components of a mixture by solvent extraction.arrow_forward
- A student was careful to make and stir all of her standard solutions immediately before measuring their turbidity for her calibration curve. However, she let her tap water solutions sit for 10 minutes prior to measuring their turbidity. If she measured the top portion of the solution, would her experimental sulfate ion concentration be higher or lower than it should be?arrow_forward2.
