Latex is a colloidal solution of rubber particles which are:A. Positively chargedB. Negatively chargesC. NeutralD. Can be negatively and positively charged

To determine the charge of the rubber particles in latex, we can analyze what latex is and its properties.

Explanation:

What is Latex?

Latex is a colloidal suspension primarily made up of rubber particles (usually polyisoprene) dispersed in water. It is commonly derived from the sap of rubber trees (Hevea brasiliensis).
Charge of Particles:

In colloidal systems, particles can carry different charges based on their surface properties and the medium they are in. For latex, the rubber particles are typically negatively charged. This is due to the presence of specific functional groups and the nature of the particles in an aqueous environment.
Interactions in Colloids:

The negative charge on the rubber particles helps to stabilize the colloid by preventing the particles from aggregating. This electrostatic repulsion between similarly charged particles keeps the colloidal suspension homogeneous.
Based on the above explanation, the correct answer is:

B. Negatively charged.
