Question

demonstrate Tyndall effect for milk and salt solution
​

Answer 1

$\huge\red{Answer}$

Milk is a colloidal solution. The particles of a colloidal solution are large enough to scatter a beam of light through it which makes it's path visible. This shows that milk shows Tyndall Effect.

Answer 2

Colloidal Solution shows Tyndall effect

Explanation:

• Tyndall effect is nothing but the effect of scattering of light in colloidal dispersion that shows no light in a true solution. The light collides with the colloidal particles and gets scattered (deviated) from its normal trajectory direction which is a straight line.
• In short, the scattering of light by the colloid particles is known as the tyndall effect. Therefore, it can be concluded that colloids show tyndall effect due to their particles are big in size enough to scatter the beam of light passing through them.
• Milk and starch solution are colloidal solutions, hence due to which it show tyndall effect.
• This type of effect is shown by those mixtures which are colloids and the salt water is a solution. Hence, salt water doesn't show Tyndall effect.
