In the form of what particles are weak electrolytes predominantly present in the solution? Are insoluble substances present

In the form of what particles are weak electrolytes predominantly present in the solution? Are insoluble substances present in the solution – precipitates or gases? How are weak electrolytes, precipitates and gaseous substances written in ionic reaction equations?

Weak electrolytes in solution are present mainly in the form of molecules. Insoluble substances – precipitates and gases – are not present in the solution. Weak electrolytes, precipitates and gaseous substances are recorded in undissociated form, i.e. in the form of molecules.
