Conjunctions are words that have the function of joining two clauses in a single sentence, promoting fluidity and transition between clauses. Regarding the conjunction "so" we can say that it is used to demonstrate that the second clause is a outcome of the information presented in the first clause, especially when the two clauses are independent.
As an example, we can use the sentence: I drink a lot of water every day, so I am very hydrated.
