Dissolve and split both undo a whole, with a difference in how. Dissolve is for a solid to break down into a liquid, or for a body to be formally ended so nothing stands. Split is to break one thing along a line into two, often forcefully. Dissolve breaks a whole down until nothing stands; split breaks it sharply into two parts.
Both undo a whole, but dissolve breaks it down and split cleaves it in two. Dissolve, from dis- 'apart' and solvere 'to loosen', lets a solid lose its shape into a liquid, or ends a body so nothing stands. Split, an old word for a forceful lengthwise break, breaks one thing along a line into two. A company is dissolved and simply ceases to exist; a company splits into two firms that both carry on. One loosens a whole apart into nothing; the other cleaves it into two.
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.
split
To split is to break something apart along a line — a log splits under the axe, a plank splits with the grain, a party splits over a policy. It is more forceful and everyday than divide, and the break is not always equal. From an old Germanic root meaning 'to cleave'. Figuratively, couples split up, a bill is split, and a difference is split down the middle. As a noun, a split is the crack or division itself — a split in the party.

Ask whether a whole breaks down or cleaves into two. Dissolve loosens a whole apart until nothing stands — a sugar cube clouding away, a company ended. Split breaks one thing along a line into two that carry on — a log falling open, a firm into two. If a body breaks down or is ended, that is dissolve; if it breaks sharply into two, that is split.

Dissolve ends a whole — a body wound up, or a solid lost into liquid; split cleaves one thing into two that each carry on. A company can be dissolved (gone) or split (into two firms). The tell is the outcome — nothing standing (dissolve) versus two parts (split).
