Gothika

Gothika is a 2003 supernatural horror film directed by Mathieu Kassovitz and written by Sebastian Gutierrez. Halle Berry plays a psychiatrist in a women's mental hospital who wakes up one day to find herself on the other side of the bars, accused of having murdered her husband.

The film was first released on November 21, 2003 in the United States. At the time of its release, Gothika was the most successful film from Dark Castle Entertainment with $141.6 million.

Plot

Psychiatrist Dr. Miranda Grey (Halle Berry) works at a mental hospital and has a car accident after trying to avoid a girl (Kathleen Mackey) on a road during a stormy night while driving back home. She rushes to try to help the girl. The girl turns out to be a ghost and possesses Miranda's body by burning her after she extends her hand to the girl. Miranda loses consciousness. Miranda next wakes up in the very hospital she works for, but as a patient treated by her co-worker, Dr. Pete Graham (Robert Downey, Jr.). Drugged and confused, she remembers nothing of what happened after the car accident. To her horror, she learns that her husband Douglas (Charles S. Dutton) was brutally murdered and that she is the primary suspect. While Miranda copes with her new life in the hospital, the ghost uses her body to carry out messages (most noticeably, she carves the words "Not Alone" into Miranda's arm), which leads her former colleagues to believe Miranda is suicidal and is inflicting the wounds on herself.

Oxidizing agent

In chemistry, oxidizing agent has two meanings. In one sense, an oxidizing agent is a chemical species that removes an electron from another species. It is one component in an oxidation-reduction (redox) reaction. In the second sense, an oxidizing agent or an oxidizer is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. Combustion, many explosives, and organic redox reactions involve atom-transfer reactions.

Electron acceptors

Electron acceptors participate in electron-transfer reactions. In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor. A classic oxidising agent is the ferrocenium ion [Fe(C₅H₅)₂]⁺, which accepts an electron to form Fe(C₅H₅)₂.

Extensive tabulations of ranking the electron accepting properties of various reagents (redox potentials) are available, see Standard electrode potential (data page).

Mechanism

Of great interest to chemists are the details of the electron transfer event, which can be described as inner sphere or outer sphere.
