Assertion: Isoelectric point ispHpHat which colloidal can move towards...
Assertion: Isoelectric point is the pH at which colloidal particles can move towards either electrode.
Reason: At the isoelectric point, colloidal particles become electrically neutral.
Explanation:
The isoelectric point (pHpHat) is the pH at which the net charge on the colloidal particles is zero. It is an important parameter that determines the behavior of colloidal particles in an electric field. The movement of colloidal particles towards either electrode depends on their charge.
Assertion is false: At the isoelectric point, colloidal particles are not attracted to either electrode. This is because they have no net charge and are electrically neutral. As a result, they do not experience any electrostatic forces that would cause them to move towards either the positive or negative electrode.
Reason is true: At the isoelectric point, the colloidal particles lose their surface charge and become electrically neutral. This occurs when the pH of the solution is such that the surface of the particles is neither positively nor negatively charged. The loss of surface charge leads to the formation of a stable equilibrium between the particles and the surrounding medium.
Explanation of the reason: The reason given is correct in stating that at the isoelectric point, colloidal particles become electrically neutral. This is because the surface groups on the colloidal particles, which are responsible for their charge, are either protonated or deprotonated depending on the pH of the solution. When these surface groups are neutral, the colloidal particles have no net charge.
However, the assertion is false because at the isoelectric point, colloidal particles do not move towards either electrode. In fact, they tend to remain dispersed in the solution without any significant movement. This is because the absence of a net charge means that there is no electrostatic force to drive the particles towards either electrode.
Therefore, the correct answer is option 'B' - Assertion is false but the reason is true.
