When the word to is followed by a verb, it is an infinitive; for example, to walk, to look, to talk. Thus, to walk is the infinitive form of the verb walk. The word to is not used as a preposition. Infinitive makes use of the base form of a verb to follow to, without a change in its form to express a function such as a tense, mood, person, number, case and gender. Without to, the verb form is called the bare infinitive, and sometimes, the form that follows to is called the to-infinitive or the full infinitive (to + simple form/base form of the verb).

Its is different from it’s. When an apostrophe is not used with the word its, it indicates possession or determiner. When an apostrophe is used, it’s is a contraction of it is. Its is used to indicate it is or it has. Inserting an apostrophe so that it becomes it's when you mean possession makes the sentence wrong grammatically.
Without an apostrophe, the word its indicates belonging to a noun that has already been mentioned.Without apostrophe
