The correct answer is B. Two oppositely-charged ions
Explanation:
In chemistry, ionic bonds only occur between ions oppositely charged, this means one of the ions has to be positively charged and the other has to be negatively charged. This is because there is a natural attraction between particles with different charges and this leads to the formation of chemical bonds. Also, this bond implies the transfer of electrons between ions. In this context, this type of bond can only occur with oppositely-charged ions. Moreover, particles with the same charges either negative, positive, or neutral do not experience attraction and cannot form ionic bonds.
Water molecules will move from the side of higher concentration to the side de of lower concentration until both solutions are isotonic at this point the equilibrium will be reached.
