In a beaker containing colloidal solution of sodium thiosulphate and a drop of con. sulphuric acid, light observed from side of beaker is:

Q. Why is Sodium thiosulphate and sulfuric acid used in the experiment of scattering of light in colloidal solution ?

Q. The sulphuric acid solution present in three different beakers in the lab is given below.

Beaker A	$2L324ml$
Beaker B	$1.585L$
Beaker C	$0.878L$

Evaluate the following expression.

(Volume of sulphuric acid in beaker B $+$ Volume of sulphuric acid in beaker C) $-$ Volume of sulphuric acid in beaker A

Q.

The above diagram shows the arrangement for observing scattering of light in colloidal solution, why does the beaker appear blue?

Q. You put identical cells into three beakers X, Y, and Z. Beaker X contains distilled water, beaker Y contains a normal saline solution, and beaker Z contains saturated salt solution. All beakers contain the same amount of solution. Identify the correct observation from the following:
