Explanation:
Colloid consist of dispersed phase and dispersed medium here dispersed medium is gas consist of isobutane and isopentane (the volatile propellant) and the liquid is a dispersed phase Shaving cream produce foam which is colloidal system wherein a gaseous phase is dispersed within a liquid continuous phase. All whipped and shaving cream come under this category of colloid.

\(10\) लीटर सॉल को दो घण्टे में अवक्षेपित करने के लिये \(0.585 \) ग्राम सोडियम क्लोराइड लगता है, तो सोडियम क्लोराइड का फ्लोकूलेशन मान होगा
1 \(0.585\)
2 \(0.0585\)
3 \(0.1\)
4 \(1\)
Explanation:
The molar mass of \(NaCl\) is \(58.5\, g / mol\) no. of moles \(=\frac{\text { mass }}{\text { molar mass }}=\frac{0.585}{58.5}=10\, millimoles\) Flocculation value of \(NaCl =\frac{\text { millimoles }}{ \text {Vol of sol in litres }}=\frac{10}{10}=1\)
