What happens to colloid at isoelectric point?

At isoelectric point, colloidal particles become electrically neutral.

What does the isoelectric point indicate?

The isoelectric point (pI) is the pH value at which the molecule carries no electrical charge. ... The pI value can be used to indicate the global basic or acidic character of a zwitterionic molecule, and compounds with pI > 7 can be considered basic, and those with pI < 7 can be considered acidic.
