जब परिक्षेपण माध्यम जल हो तो कोलॉइडी तंत्र को कहते हैं
1 सॉल
2 एरोसॉल
3 ऑर्गेनोसॉल
4 एक्वासॉल
Explanation:
A colloid is a heterogeneous system in which one substance is dispersed (dispersed phase) as very fine particles in another substance called dispersion medium. Thus when the dispersion medium is water, it is known as "Aquasol".

जब ताजे अवक्षेपित पदार्थ को कोलॉइडी विलयन में तीसरे पदार्थ की सहायता से बदला जावे, तो यह क्रिया कहलाती है
1 स्कन्दन
2 पेप्टीकरण
3 विद्युत परिक्षेपण
4 अपोहन (Dialysis)
Explanation:
Peptization or Deflocculation is the process responsible for the formation of converting precipitate into colloid by shaking with it an electrolyte.

\(A{s_2}{S_3}\) कोलॉइड के लिये निम्नलिखित में से किसकी स्कन्दन क्षमता सबसे अधिक होती है
1 \(PO_4^{ - 3}\)
2 \(SO_4^{ - 2}\)
3 \(N{a^ + }\)
4 \(A{l^{3 + }}\)
Explanation:
Arsenious sulphide is negatively charged saol, hence it will be coagulated be positive ion having maximum amount of charge hence, \(Al ^{3+}\) have maximum coagulating power.
