There is no such thing. A sacrament is an outward sign of inward grace; a sin is a transgression; sin as a state or status is a defect, specifically estrangement from God, or an absence of grace. It does not necessarily have any outward manifestation. So, sin and sacramental objects, actions, or words are opposites. A "sacrament of sin" would be like saying the "blackness of white."
Catholics believe that the Sacrament of Baptism forgives Original Sin and all personal sin.
You can receive the sacrament of Penance if you have any sin including not only mortal sins but venial sins as well. If you have sin, it is recommended but not necessary to receive the sacrament (Except for mortal sins where you must confess it)
The sacrament of Penance (Confession) cleanses us, so does Annointing of the Sick as well. Also, baptism in a way cleanses us too since it removes our original sin but it is not listed as a sacrament of healing.
If you are absolved in the sacrament of penance.
Sin entered the world.
Reconciliation
No. Only baptism washes away original sin.
No! sacrament is only a system that administered us and the sacramentals is the things that made the man pure without stain of sin.
