One of the following statements is incorrect Select one: O Back-titration is required when the rate of the reaction slow. O A standard solution should react completely with the analyte without a definite chemical equation. Standardization is required when the titrant solution molarity is approximate. O A primary standard should be highly pure, has atmospheric stability and absence of hydrated water. O Titration error is the difference between equivalence point volume and end point volume.

A sample may contain NaOH, NazCO3 and NaHCO3, alone or in some combination, along with inert material. A samplewitha mass of 857.6 mgwas dissolved and titrated with0.1163 M HCI. The volume of HCl used from 0 to methyl red endpoint (Phenolphthalein endpoint was not monitored here) was found to be 36.54 mL. Another 228.8 mg portion of the sample was titrated to the phenolphthalein endpoint and 10.82 mL was used up for this titration. a. What is the composition of the sample? b. Calculate the percentage of each of the component present.
Advantages of potentiometric titrations over 'classical' visual indicator methods: (select the correct statement(s)). Can be used for colored, turbid or fluorescent analyte solution. Can be used if there is no suitable indicator or if the color change is difficult to visualize. Both answers 1 and 2 are correct

5. A 300.0 mg sample containing Na,CO3, NaHCO3 and NaOH and inert material either alone or in some combination was dissolved and titrated with 0.1000 M HCI the titration required 24.41 mL to reach the phenolphthalein endpoint. And an additional 8.67 mL to reach the methyl red endpoint. Determine the composition of the sample and calculate the percent of each titrated component.
