English हिन्दी

_____ is the determination of one or few constituents from the sample:

1. Partial analysis
2. Complete analysis
3. Proximate analysis
4. Ultimate analysis

नमूने (sample) से केवल एक या कुछ घटकों का निर्धारण करना कहलाता है:

1. आंशिक विश्लेषण (Partial analysis)
2. पूर्ण विश्लेषण (Complete analysis)
3. सन्निकट विश्लेषण (Proximate analysis)
4. चरम / मूल विश्लेषण (Ultimate analysis)
EXPLANATION Volumetric and Gravimetric Analysis, Acid-Base Equilibria and Buffer Systems

In analytical chemistry, chemical analyses are classified based on the extent of constituents measured:

  • Partial analysis: The determination of one or only a selected few constituents of interest in a sample.
  • Complete analysis: The determination of all the chemical constituents present in a sample.
  • Proximate analysis: The determination of groups of chemically related compounds or classes (e.g., moisture, ash, crude protein, crude fat).
  • Ultimate analysis: The determination of individual chemical elements (C, H, N, S, O) present in a substance.
Therefore, the determination of one or few constituents is Partial analysis.

रासायनिक विश्लेषण के प्रकार:

  • आंशिक विश्लेषण (Partial analysis): नमूने में से केवल एक या कुछ चुने हुए विशिष्ट घटकों का मात्रात्मक निर्धारण।
  • पूर्ण विश्लेषण (Complete analysis): नमूने के सभी घटकों का निर्धारण।
  • सन्निकट विश्लेषण (Proximate analysis): संबंधित यौगिकों के समूहों (नमी, राख, वसा आदि) का निर्धारण।
  • मूल विश्लेषण (Ultimate analysis): शुद्ध तात्विक संघटन (C, H, N, S आदि) का निर्धारण।
अतः सही उत्तर आंशिक विश्लेषण है।
