Q10) A tablet that contained 500 mg of vitamin C (Molar Mass = 176 g/mol) was titrated with 20.15 mL of KIO, to the blue end point. The same KIO, solution was used to titrate 12.1 mL of a commercial juice blend. The juice blend required 2.40 mL of KIO, to reach the end point. How many milligrams of vitamin C are in the sample of juice blend a) 0.047 mg b) 0.05956 mg c) 47.0 mg d) 59.56 mg Q11) The following symbol indicates a) Toxic chernicals b) Oxidizing reagent c) Harmful iritant d) Flammable material Q12) The primary standard must satisfy one of the following criteria a) Available in pure form b) Unstable c) hygroscopic d) Has Low molecular weight Q13) During the titration technique, the titration process is stopped at a) Equivalence point b) Stoichiometric point c) Initial point d) End point Q14) During vitamin C analysis, the indicator tums into blue in presence of a) I b) I, c) IO, d) HCI Q15) A piece of solid material was immersed in 5 mL water in graduated cylinder. If the volume of water increased to 10 mL and the mass of solid material is 1 g. the density of the solid material is a) 2 g/mL b) 0.01 g/mL c) 0.2 g/ml d) 0.1 g/mL
