Question

What does it mean to "standardize" a solution? Why is this important? 1. Last week you created a triangular phase diagram for use in understanding ternary mixtures. This is a common application in geology. Consider the diagram below and the numbered points. a. What is the composition at point 12? b. If a tie-line were to be drawn that connected points 10-13-12-14, what would you 2. interpret it to mean? Sandstone 9100% 80% 40% 12- 60% 40% 13 20 % 14 10 Shale Limestone Professor Best is entertaining guests one Saturday night and decides to serve a green salad dressed with his special vinaigrette. He adds honey, lemon, oil, and vinegar in a ratio of 1:2:4:8 and whisks the mixture until it emulsitfies. He then sets it in the refrigerator to chill. a. How many degrees of freedom does this mixture have immediately after mixing? b. After twenty minutes, Professor Best rescues the dressing from the refrigerator and notices that it tastes horrible. Upon consideration, he realizes that the oil to vinegar ratio should have been 3:1. How much oil should be added to the mixture if each unit of measurement is 1 TBSP? (How many more TBSPS?) 3. c. Upon adding the additional oil, the mixture separates into three layers. How many degrees of freedom does the mixture have now? 100% - %og 20% -%09 60% -%02 80% 100%

Answer 1

Ans 1 :

Standardizing the solution means to determine the exact concentration of the solution.

This standardization can be done using the titration procedure.

Standardization of the solution is important so that the solution whose exact concentration is known , can be used to determine the concentration or the amount of other substance in the procedure and perform other calculations as well.
