1. bleaching

   Bleach is the generic name for any chemical product that is used industrially or domestically to remove color (whitening) from a fabric or fiber or to clean or to remove stains in a process called bleaching. It often refers specifically to a dilute solution of sodium hypochlorite, also called "liquid bleach". Many bleaches have broad spectrum bactericidal properties, making them useful for disinfecting and sterilizing. They are used in swimming pool sanitation to control bacteria, viruses, and algae, and in many places where sterile conditions are required. They are also used in many industrial processes, notably in the bleaching of wood pulp. Bleaches also have other minor uses like removing mildew, killing weeds, and increasing the longevity of cut flowers.Bleaches work by reacting with many colored organic compounds, such as natural pigments, and turning them into colorless ones. While most bleaches are oxidizing agents (chemicals that can remove electrons from other molecules), some are reducing agents (that donate electrons). Chlorine, a powerful oxidizer, is the active agent in many household bleaches. Since pure chlorine is a toxic corrosive gas, these products usually contain hypochlorite, which releases chlorine. "Bleaching powder" usually means a formulation containing calcium hypochlorite. Oxidizing bleaching agents that do not contain chlorine are usually based on peroxides such as hydrogen peroxide, sodium percarbonate, and sodium perborate. These bleaches are called 'non-chlorine bleach,' 'oxygen bleach' or 'color-safe bleach.'Reducing bleaches have niche uses, such as sulfur dioxide used to bleach wool, either as gas or from solutions of sodium dithionite; and sodium borohydride. Bleaches generally react with many other organic substances besides the intended colored pigments, so they can weaken or damage natural materials like fibers, cloth, and leather, and intentionally applied dyes such as the indigo of denim. For the same reason, ingestion of the products, breathing of the fumes, or contact with skin or eyes can cause health damage.

Examples of Bleaching in a Sentence

1. Dr James Kerry:

   The central section of the reef is now displaying the same extent of bleaching as in the north, going over those reefs this year, you can tell how low the coral cover was. It was shocking to see the fallout from last year's event.

2. Jodie Rummer:

   Even the most robust corals require nearly a decade to recover. So we're really losing that window of recovery, we're getting back-to-back bleaching events, back-to-back heat waves. And, and the corals just aren't adapting to these new conditions.

3. Jodie Rummer:

   The bleaching now is not just restricted to the hard corals. There’s also extensive bleaching in the soft corals, and it is also affecting anemones and giant clams.

4. Marie Strader:

   We intended this paper to serve as a humble blueprint for how researchers can use this technology to study the functions of coral genes, we are currently conducting experiments investigating how specific genes regulate coral skeletal formation, or calcification, for example. However, we expect this technique could be useful to identify genes involved in many other ecologically important traits such as thermal tolerance or coral bleaching.

5. Terry Hughes:

   This has been the saddest research trip of my life, almost without exception, every reef we flew across showed consistently high levels of bleaching, from the reef slope right up onto the top of the reef. We flew for 4000 kilometers (2,485 miles) in the most pristine parts of the Great Barrier Reef and saw only four reefs that had no bleaching. The severity is much greater than in earlier bleaching events in 2002 or 1998.
