Dissolve and unite are opposites. Dissolve is for a solid to break down and disappear into a liquid, or for a body to be formally ended. Unite is to join parts or people into one for a shared cause. Dissolve breaks a body down or winds it up; unite joins people into one.
They act on a body in opposite ways. Dissolve, from Latin dissolvere 'to loosen apart', breaks a solid down until it vanishes, or ends an organization — a parliament or union is dissolved. Unite, from Latin unus 'one', joins people into a single body around a cause. A movement unites people; a government can later dissolve it, or the movement dissolve itself. One loosens a body apart until it is gone; the other binds scattered people into one.
dissolve
To dissolve is for a solid to break apart into a liquid until it disappears into it — sugar dissolves in water — or, by extension, for something to fade out or be formally ended (a marriage, a company, a parliament is dissolved). From the Latin dissolvere, 'to loosen apart', from solvere 'to loosen', the root of solve and solvent. A substance dissolves when its particles separate and spread evenly through the liquid — the reverse of what happens when droplets coalesce. Governments dissolve; tension dissolves; a crowd can dissolve into laughter.
unite
To unite is for separate people, groups, or parts to come together and act as one — from the Latin unus, 'one'. A crisis unites a divided nation; scattered rebels unite behind a leader; two kingdoms unite under one crown. The word carries a charge of solidarity: those who unite often stay distinct yet stand together, as allied armies do when they unite against a common enemy. To unify is to make one cohesive whole; to unite is to join forces — to combine strength while keeping your own name.

Watch whether a body is being loosened apart or bound together. Dissolve breaks a solid down until it vanishes, or ends a body outright — the sugar cube lost into the water. Unite draws scattered people into one closed ring for a cause. If a body breaks down or is wound up, that is dissolve; if scattered people are joined into one, that is unite.

For an organization dissolve and unite are near-opposites — people unite into a body, or a body is dissolved and ceases to exist. But dissolve also covers the chemistry sense (a solid breaking down in liquid) that unite never touches. Unite carries solidarity; dissolution is an ending or a breaking-down.
