What is your suggested way of working?When standardizing two liters of a potassium permanganate solution, approximately 0.0100 M, with a primary standard solution of sodium oxalate, it was planned to use between 30.00 and 45.00 ml of the titrated reagent. In which mass range (in grams) the primary standard should be weighed?A sample containing BTEX What is the appropriate quantitative and qualitative analysis method for it in the laboratory?

Express the anwer in mgmg to three significant figures.f the mass of the KHP is 0.550 g and the average volume of the prepared NaOH solution consumed in the titration is 33.0mL, what is the standardized concentration of NaOH?How many milligrams of MgI2 must be added to 275.0 mL of 0.0788 M KI to produce a solution with [I−] = 0.1000 M?
- You are required to standardize a dilute solution of sulphuric acid, and undertake the following steps:(i) 4.805 g of solid sodium tetraborate (Na2B4O7) are added to a 250 mL volumetric flask, and the solution made up to the mark with distilled water.(ii) 25.00 mL aliquots of the stock solution from (i) are transferred to conical flasks, for titration against the sulphuric acid solution in the burette.(iii) You perform titrations using two different indicators: bromocresol green, and phenolphthalein.With bromocresol green, the average titre volume is 22.50 cm3, while with phenolphthalein, the average volume is 9.50 cm3.(a) Write the balanced equation for the reaction between Na2B4O7 and sulphuric acidThe chloride ion content of a 250.0-mL seawater sample was titrated against 0.1102 M silver nitrate, requiring 13.56 mL to reach end point. How many moles of chloride ion is present in the sample?Titration of a 25.00 mL sample of acid rain required 12.4 mL of 0.009879 M NaOH to reach the end point.

- Explain the three process of gravimetric analysis1. This is the mass of the substance that is chemically equivalent to a cubic centimeter (cc) of the standardsolution2. This is a solution used in the titrimetric analysis expressed in its known Molarity or Normality concentration.3. This is the solution, or the substance being determined by the chemical analyst through titration.4. This is the theoretical chemical point at which both solutions have equally reacted resulting to the end ofthe chemical reaction5. This is the point at which the reaction of the chemicals causes the production or change in the color of thesolution.6. The analysis involving the slow addition of the standard solution to the analyte.7. A chemical added to the titration process that causes an observable change in color its color when equalamounts of the two chemicals have reacted or near the equivalence point.The concentration of CO in air is determined by passing a known volume of air through a tube that contains I2O5, forming CO2and I2. The I2 is removed from the tube by distilling it into a solution that contains an excess of KI, producing I3-. The I3-is titrated with a standard solution of Na2S2O3. In a typical analysis a 4.79-L sample of air is sampled as described here, requiring 7.17 mL of 0.00329 M Na2S2O3 to reach the end point. If the air has a density of 1.23 × 10–3 g/mL, determine the parts per million CO in the air
