H3PO3 (फॉस्फोरस अम्ल) की क्षारकता है

Last Updated:

यह SSC CGL रसायन प्रश्न पूछता है: “H3PO3 (फॉस्फोरस अम्ल) की क्षारकता है” सही उत्तर 2 है। H3PO3 में 2 P-OH समूह हैं इसलिए इसकी क्षारकता 2 है। विश्वसनीय उत्तर के लिए पहले पहचानें कि प्रश्न परमाणु संरचना, रासायनिक बंधन, आवर्त प्रवृत्ति, स्टॉइकियोमेट्री, अम्ल-क्षार, रेडॉक्स, वैद्युत रसायन, कार्बनिक नामकरण, धातुकर्म या दैनिक उपयोग के पदार्थों में से किस विषय पर है। अम्ल की basicity ionisable proton की संख्या है, केवल सूत्र में लिखे सभी hydrogen की नहीं।

A1
B2

FAQ

SSC CGL रसायन विज्ञान FAQs

Common questions and clear answers for this topic.

How many chemistry questions typically appear in the SSC CGL exam?

Chemistry usually contributes a handful of questions within the General Awareness section, generally covering basic concepts rather than calculation-heavy problems.

Which chemistry topics are most important for SSC CGL preparation?

Atomic structure, periodic table trends, acids-bases-salts, metals and non-metals, and carbon compounds are the areas that appear most consistently across past papers.

Is NCERT chemistry enough to prepare for SSC CGL?

NCERT textbooks from classes 9 and 10 cover most of the conceptual base needed, though supplementing with general knowledge about everyday chemical compounds helps too.

What is the best way to remember chemical reactions and formulas for SSC CGL?

Linking reactions to real-world examples, like rusting or antacids, makes them easier to recall than memorizing formulas in isolation.

Does the SSC CGL chemistry syllabus overlap with the school board syllabus?

Yes, a large part of the syllabus mirrors class 9 and 10 science, making school-level revision a practical starting point.
