WebThe solvent molecules (water in this case) surround the ions removing them from the crystal and forming the solution. As the dissolving process proceeds, the individual ions … WebTranscribed Image Text: Metal ions in aqueous solutions are solvated, or hydrated, by water molecules. Typically this primary hydration sphere is composed of six water molecules. The hydrated metal ion acts as a weak acid, undergoing a stepwise hydrolysis in which it donates an H+ ion from its water ligands to the surrounding free water … grants and trusts fundraising
