Why are alkalis dangerous

Proteins can be chemically denatured through both electron-donating and electron-accepting reactions. Therefore, both acids and bases can denature the proteins of your skin cells. If the burn is caused by an acid, then the denatured proteins remain in place and effectively form a protective barrier against deeper skin damage. Bases decompose fats triglycerides through a chemical reaction called saponification.

Below is a graphic of the chemical reaction which occurs. As you can see saponification shreds the fat triglyceride molecule into four separate pieces, which transforms them from solid to liquid. Saponification is the first step in the process used to render animal and vegetable fats into soaps and glues. As the fats are turned to liquids they flow away from the site of the burn which exposes new skin to further injury.

This s allows a chemical burn from an alkali to burrow deeply into the skin in a process known rather gruesomely as liquefaction necrosis and explains why chemical burns from a base are often far worse than from an acid. I am frankly quite surprised that it is permissible to use a product such as this in a public environment like an apartment complex.

Given that it is permissible, the residents of Pine Gate Apartments should have been given far better information on the hazards present to themselves and their pets. Better yet, a less hazardous paint removing approach should have been considered. I hope that it at least the new paint applied after stripping was completed looks nice. Have a comment or question?

Think that this column includes important points that others should consider? Both classified as Class 8 Corrosive Substances, they can eat away at other materials, causing damage to stone, metal and even human skin when coming into contact. As mentioned, both acids and bases are Class 8 hazardous waste substances, but they do differ slightly.

The pH scale ranges from 0 to 14, with a pH of 7 considered neutral. Acids, which neutralize bases, have a pH level of less than 7. Bases, which neutralize acids, have a pH level higher than 7.

The strength of each is based on this scale. The simple answer is that both acids and bases can be dangerous depending on their pH level, or how strong they are. Bases and alkalis Bases v alkalis A base is a substance that can react with acids and neutralise them. Bases are usually: metal oxides, such as copper oxide metal hydroxides, such as sodium hydroxide, or metal carbonates, such as calcium carbonate Many bases are insoluble - they do not dissolve in water.

The table shows two examples of bases: Copper oxide Sodium hydroxide Can it neutralise acids? Yes Yes Is it a base? Yes Yes Can it dissolve in water? No Yes Is it an alkali? No Yes All alkalis are bases, but only soluble bases are also alkalis Bases in the laboratory Household cleaning products contain strong bases, such as sodium hydroxide solution.

Bases in the home Bases react with oils and fats, so they are often used in household cleaners.
