Hard Chemistry Chapter 01: Solutions Class 12 Level 7

किसी ठोस को बहुत बारीक पीसने से घुलने की गति क्यों बढ़ सकती है?

Why can grinding a solid into fine powder increase its rate of dissolving?

Explanation opens after your attempt
Correct Answer

A. सतह क्षेत्र बढ़ जाता है / Surface area increases

Step 1

Concept

Fine particles have larger total surface area.

Step 2

Why this answer is correct

Larger surface area increases contact between solute and solvent.

Step 3

Exam Tip

Grinding affects rate, not the saturated solubility limit. चरण 1: बारीक कणों का कुल सतह क्षेत्र अधिक होता है। चरण 2: अधिक सतह क्षेत्र से विलेय और विलायक का संपर्क बढ़ता है। चरण 3: बारीक पीसना गति को प्रभावित करता है, संतृप्त विलेयता को नहीं।
