Chapter 3, Problem 3.17P
Interpretation Introduction

(a)

Interpretation:

Plot a calibration curve using given data.

Concept introduction:

100 g of pure water and different weighed quantities of amino acid L-isoleucine (Ile) were added to six flasks to prepare aqueous solutions. Then the densities of solutions were measured using densitometer, with the following results.

r (g Ile/100 g H2 O) 0 0.8821 1.7683 2.6412 3.4093 4.2064
Ρ (g solution /cm3) 0.98803 0.98984 0.99148 0.99297 0.99439 0.9958

A calibration curve, r=aρ+b can be drawn using above data. Where, a = slope, b = intercept, Ρ = density and r = concentration

Interpretation Introduction

(b)

Interpretation:

Using the calibration curve calculate the mass flow rate of the given stream.

Concept introduction:

100 g of pure water and different weighed quantities of amino acid L-isoleucine (Ile) were added to six flasks to prepare aqueous solutions. Then the densities of solutions were measured using densitometer. Using observed data, a calibration curve was drawn and given by the formula,

r=545.5ρ539.03

Where, Ρ = density and r = concentration

In addition, it is given as,

Density = 0.994 g / cm3, Volumetric flow rate = 150 L/h

Interpretation Introduction

(c)

Interpretation:

If the thermocouple is poorly calibrated. Would the mass flowrate estimated in section (b) be too high or too low?

Standardization of a sodium hydroxide (NaOH) solution against potassium hydrogen phthalate (KHP) yielded the following results: Mass of KHP, g Volume of NaOH, mL 0.7987 38.29 0.8365 38.96 0.8104 38.51 0.8039 38.29 MM KHP: 204.22 MM NaOH: 40.00 a. Calculate the mean molar concentration of sodium hydroxide. (First, compute the concentration of NAOH in each titration then compute for its mean/average value.) b. Calculate the standard deviation. Please provide solutions for your answers. If you have used your calculator for calculating for mean and standard deviation, you can just provide the formula with the values indicated.
A solution is prepared by dissolving 40.00 g of MgCl2 (f.w. = 95.211 g mol–1), a non-volatile solute, in enough water (m.w. = 18.02 g mol–1) to result in exactly 2 L of solution at 25 °C. Assume the density of the solution is that of pure water (dsolution = 1.000 g mL–1). The ebullioscopic constant (Kb) for water is 0.513 °C m–1. The cryoscopic constant (Kf) for water is 1.86 °C m–1. The vapor pressure of pure water is 0.0313 atm. Determine the freezing point of the solution.
