Question

charge of solution particles whether positive or negative can determined by
​

Answer 1

Answer:

Surface charge is a two-dimensional surface with non-zero electric charge. These electric charges are constrained on this 2-D surface, and surface charge density, measured in coulombs per square meter (C•m−2), is used to describe the charge distribution on the surface. The electric potential is continuous across a surface charge and the electric field is discontinuous, but not infinite; this is unless the surface charge consists of a dipole layer. In comparison, the potential and electric field both diverge at any Point Charge or Linear Charge.

Electrophoresis method

Charge of solution particles whether positive or negative can determined by electrophoresis method.

• The electrophoresis phenomenon, in which colloidal particles flow toward oppositely charged electrodes under the influence of an electrical field, can be used to identify the presence of the charge on the sol particles and its composition.
• The electrophoresis method can be used to determine the charge on any sol particle. The analysis of DNA and the research of DNA fragments is one of the most significant uses of electrophoresis. DNA (or deoxyribonucleic acid) is impacted by an electrical current because of the consistency of the negative charge it carries.
• Colloidal particles that have a charge travel toward one of the electrodes in an electric field during electrophoresis.
• The charge of the molecule, viscosity, and atom radius all affect electrophoretic mobility. The applied electric field directly affects how quickly a particle goes; the stronger the field, the more quickly it moves. A separation technique known as electrophoresis relies on the movement of charged species in a supporting medium (a liquid or a hydrophilic gel) when they are subjected to an electric field.
