THE QUESTION IS AT THE PICTURE... 2 QUESTIONS ONLY.. AND THE GIVEN PROBLEMS IS THE ONE I TYPED... example table is shown.. but im not sure if it is correct... disregard my answer if it is wrong... C. Temperature1. Place 5 mL each of 0.1N sodium thiosulfate solution into 5 test tubes.2. Place all five test tubes in the water bath and let it stand for 1 minute.3. Record the temperature of the water bath. Remove the first test tube from thewater bath and place it in the test tube rack.4. Add 1 mL of 0.1M sulfuric acid and stir with a glass rod. Record the time it takes forthe turbidity to appear.5. Increase the temperature of the water bath by about 10℃, as you remove the 2ndtest tube and do step 4.6. Do the same with the 3rd, 4th, and 5th test tubes with 10℃ rise in the temperature.

Often the analyst will compare known quantities of analyte to unknown quantities of the material to be analyzed. This may be done in one of three ways: -use calibration curves; use standard additions; or use internal standards. The method of standard additions would be used when A) the quantity of sample analyzed or the instrument response varies from run to run. B) the standard solutions and the unknown solution all have similar characteristics are unaffected by the other material in the sample. C) the sample composition is unknown or complex and affects the analytical signal.
