In the reaction $SO_{2(g)} + 2H_2S_{(g)} \rightarrow 3S_{(sol)} + 2H_2O_{(l)}$,which method is used to obtain the sulfur sol?

The critical micelle concentration $(CMC)$ of a soap solution is $5 \times 10^{-4} \ mol \ L^{-1}$. Identify the correct statements about this solution.
$I$. The micelle is stable if the soap solution concentration is $10^{-7} \ mol \ L^{-1}$
$II$. The micelle is stable if the soap solution concentration is higher than $5 \times 10^{-4} \ mol \ L^{-1}$
$III$. Micelles are also known as associated colloids.

$A$ peptising agent is

$A$ $42.12 \% (w/v)$ solution of $NaCl$ causes precipitation of a certain sol in $10 \, hours$. The coagulating value of $NaCl$ for the sol is $.....$
[Given : Molar mass : $Na = 23.0 \, g \, mol^{-1} ; Cl = 35.5 \, g \, mol^{-1}]$

On adding $AgNO_3$ solution into $KI$ solution,a negatively charged colloidal sol is obtained when they are in:

Draw the diagram showing micelle formation by the following detergent.
