    Saccharimetry is the practical application of

    • Acidimetry

    • Alkalimetry

    • Potetiometry

    • Polarimetry

    • Aquametry

    Correct Answer
    A. Polarimetry
    Explanation
    Polarimetry is the practical application of saccharimetry. Polarimetry is a technique used to measure the rotation of plane-polarized light as it passes through a sample. In saccharimetry, polarimetry is used to determine the concentration of sugar in a solution by measuring the rotation of polarized light caused by the presence of sugar molecules. Therefore, polarimetry is the correct answer as it directly relates to saccharimetry and its practical application.

    In which of the following titration “oxidation-reduction ‘(Redox) step can be expected

    • Acid-base titrations

    • Ceriometry

    • Gay-lussac method

    • Aquametry.

    • Kjeldhal titration

    Correct Answer
    A. Ceriometry
    Explanation
    Ceriometry is a titration method that involves the determination of cerium ions in a solution. In this method, the oxidation-reduction (redox) step can be expected because cerium ions can exist in different oxidation states, such as Ce3+ and Ce4+. The redox reaction occurs between the cerium ions and the titrant, which is usually a reducing or oxidizing agent. This reaction allows for the determination of the concentration of cerium ions in the solution. Therefore, in the process of ceriometry, the oxidation-reduction step is involved.

    Formality is a term for expressing the concentration and used in

    • spectrophotometric reactions

    • acid-base reactions

    • argentometric reactions

    • precipitation reactions

    • Redox titrations

    Correct Answer
    A. precipitation reactions
    Explanation
    Formality is a term used to express the concentration in various types of reactions. In this case, it is specifically used in precipitation reactions. Precipitation reactions involve the formation of a solid product from the reaction of two aqueous solutions. The formality of a solution in a precipitation reaction refers to the number of formula units of the solute present in one liter of the solution. Therefore, the correct answer is precipitation reactions.

    CO2 not identified by IR spectroscopy it’s due to

    • CO2 has no dipole moment although C=O is polar

    • CO2 has no dipole moment since C=O is non-polar

    • Optical activity of the system

    • Both (a) and (c

    • Both (b) and (c)

    Correct Answer
    A. CO2 has no dipole moment although C=O is polar
    Explanation
    The correct answer is "CO2 has no dipole moment although C=O is polar." This is because although the C=O bond in CO2 is polar due to the difference in electronegativity between carbon and oxygen, the molecule as a whole is linear and symmetrical, resulting in the dipole moments of the two C=O bonds canceling each other out. As a result, CO2 does not have a net dipole moment and cannot be identified by IR spectroscopy, which relies on the detection of molecular vibrations associated with a changing dipole moment.

      which of the following is volumetry

    • Potentiometry

    • Voltametry

    • Gravy metry

    • Gasometry

    • Amperometry

    Correct Answer
    A. Gasometry
    Explanation
    Gasometry is the correct answer because it refers to the measurement of the volume or quantity of gases. Potentiometry, voltametry, gravy metry, and amperometry are not related to the measurement of gas volume.
