A series of sulfate samples is to be analyzed by precipitationas BaSO4. If it is known that the sulfate contentin these samples ranges between 20% and 55%, whatminimum sample mass should be taken to ensure thata precipitate mass no smaller than 0.200 g is produced?What is the maximum precipitate mass to be expectedif this quantity of sample is taken?
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
