- In electrochemistry, specific conductance is defined as (1000/N)* k, where N is the normality of the salt solution and k is the specific conductance. Current is carried by both anions and cations to a different degree. Thus, the equivalence of a salt is the sum of the ionic conductances of the cation and anion. If the ionic conductance of Na+ is 50.1 and that of Cl- is 76.6. What is the estimated concentration of NaCl in mg/L. The specific conductance of NaCl is 125x106.

This question is from my reviewer.Magnesium Chloride is available as magnesium chloride hexahydrate in an injectable solution that supplies 1.97 mEq of magnesium per milliliter. What is the percent strength of magnesium chloride hexahydrate in this solution?Analytical chemistry is a particular field within the broader spectrum of the chemical sciences, in which many times the focus of analytical experiments is to develop new methods to analyze compounds, either structurally or by determining concentrations of compounds. One of the processes analytical chemists use to determine the exact concentration of a working solution is called standardization. In your own words, describe the differences between a primary, secondary, and tertiary standard, and describe the underlying concept behind the standardization process. Why is it done?
- Some wastewater stream contains 0.015 M Hg22+. Some chemical engineer decides to remove it by precipitating it as Hg2CO3(s). He mixes 100.00 ml of the wasterwater with 100.00 ml of a 2.00 M solution of Na2CO3 and filters the result to remove the solid. How much residual Hg22+ should he expect to find still in the water? (Hint: it should not be 0) Ksp of. Hg2CO3 = 9.0 x 10-15. Also keep in mind that Hg+ is the only ion that exists in solutions as a dimer, i.e. Hg22+, not 2 Hg+ (Hg2CO3→ Hg22+ + CO32-)Mr. Roy, the principal of a reputed school organized a seminar in which he invited parents and principals to discuss the serious issue of diabetes and depression in students. They all resolved this issue by strictly banning the junk food in schools and to introduce healthy snacks and drinks’like soup, lassi, milk, etc. in school canteens. They also decided to make compulsory half an hour physical activities for the students in the morning assembly daily. After six months, Mr. Roy conducted the health survey in most of the schools and discovered a tremendous improvement in the health of students. After reading the above passage, answer the following: What are the values (at least two) displayed by Mr. Roy? As a student, how can you spread awareness about this issue? What are tranquilizers? Give an example. Why is the use of aspartame limited to cold foods and drinks?5.
