The correct spelling of "dis solves" is "dissolves" which uses the IPA phonetic transcription of /dɪˈzɒlvz/. The word is spelled with double letters 'ss' as it derives from the Latin word solvere, which means "to loosen." The prefix "dis-" is added to show negation or reversal of the action of dissolving. The correct spelling is important to ensure clear communication and understanding in written language.
